Top Reasons for Low Fill Rate Issues in Google AdExchange

Top Reasons for Low Fill Rate Issues in Google AdExchange

Introduction: Understanding Fill Rate in Google AdExchange

If you’re a publisher using Google AdExchange and noticing that many of your ad requests aren’t converting into served ads, you’re likely facing a low fill rate issue.

This can be frustrating especially when you know your content attracts traffic but your monetization isn’t matching up.

Fill rate is a critical metric for digital publishers. It directly impacts how much revenue you make from your ad inventory.

Understanding the root causes of low fill rates is the first step toward improving your monetization strategy. In this article, we’ll dive deep into the various reasons behind low fill rates in Google AdExchange and how you can fix them.

What Is Fill Rate and Why It Matters 

Definition of Fill Rate 

In simple terms, fill rate refers to the percentage of ad requests that result in actual ad impressions. It shows how effectively your ad space is being utilized. 

Fill Rate Formula 

Here’s the basic formula: 
Fill Rate = (Ad Impressions / Ad Requests) × 100 
For example, if you had 1,000 ad requests and only 700 impressions, your fill rate would be 70%.

Impact on Revenue and User Experience 

A low fill rate means a lot of your inventory is going unsold. This doesn’t just lower your ad revenue; it can also lead to poor user experiences, like blank ad slots or layout shifts.

Common Reasons Behind Low Fill Rate in Google AdExchange

1. Geo-Targeting Mismatches

If your site attracts users from countries where advertisers are less active, you may struggle with low fill rates. Advertisers typically bid more aggressively in markets like the US, UK, or Australia.

2. Ad Unit Misconfiguration

Even minor errors in ad unit setup—such as incorrect sizes, invalid placements, or missing targeting criteria can cause fill issues.

3. Low Bid Density from Buyers

Sometimes, there simply aren’t enough bids for your inventory. This can be due to market conditions or low-quality content that doesn’t attract premium advertisers.

4. Policy Violations or Ad Restrictions

Google has strict policies. If your content violates any of them (e.g., adult themes, illegal content, etc.), your ad units may get limited or blocked, reducing fill rate.

5. Inappropriate Ad Sizes or Formats

Some advertisers only buy specific sizes or formats. If you’re using uncommon ad units, the pool of potential buyers shrinks.

6. Inventory Oversaturation

Too many ad units per page can lead to lower competition for each slot, resulting in some ad requests going unfilled.

7. Floor Price Too High

If your floor price is higher than what buyers are willing to pay, your impressions may not be served at all.

Technical Factors Contributing to Low Fill Rate

1. Latency Issues and Slow Page Load

When your site loads slowly, ad calls may timeout before they reach Google’s servers. This can prevent ads from rendering in time.

2. Header Bidding Conflicts

Header bidding setups can interfere with Google AdExchange if not configured correctly, affecting fill rates negatively.

3. Incorrect Ad Tags Implementation

Malformed or outdated ad tags can break the connection between your site and the adserver.

4. Limited Demand from Google Demand Partners (GDPs)

If you’re not enabled for certain GDPs or Open Bidding partners, your ad inventory may have fewer buyers competing for it.

How Ad Mediation and Header Bidding Affect Fill Rate

  • Fill Rate vs. Coverage: What’s the Difference?

Coverage refers to the percentage of ad units with at least one bid, while fill rate is about actual impressions. Don’t confuse the two.

  • Unified Pricing Rules Impact

Google’s unified pricing rules can restrict fill rates if they’re set too conservatively, especially with high minimum CPMs.

Optimization Strategies to Improve Fill Rate

  • Adjusting Floor Prices and Soft Floors

Lowering your floor prices or using soft floors can attract more bids without significantly sacrificing CPMs.

  • Expanding Geo-Targeting and Device Support

Open up your targeting to include more regions or devices to increase demand.

  • Optimizing Ad Sizes and Formats

Stick to standard IAB sizes (like 300×250 or 728×90) for maximum competition from advertisers.

  • Improving Site Speed and Reducing Latency

Use tools like Google PageSpeed Insights to identify and fix performance issues.

  • Using Passback Tags Effectively

Set up passbacks to other ad networks when Google fails to fill an impression. This ensures minimal lost revenue.

Tools to Monitor and Analyze Fill Rate in Google AdExchange

  • Google Ad Manager Reports

Create custom reports to track fill rate trends by device, geo, and ad unit.

  • Real-Time Bidding (RTB) Analytics

RTB insights help you understand why bids aren’t being placed and what’s causing fill gaps.

  • Third-Party Monitoring Solutions

Platforms like Adomik, PubGuru, and AdButler provide deeper insights and automation to improve fill rates.

Case Studies: Publishers Who Solved Low Fill Rate Issues

  • Case Study 1: News Publisher

By reducing their floor prices and enabling more device formats, a major news site saw a 25% improvement in fill rate.

  • Case Study 2: Mobile App Developer

Maximizing Revenue from CTV Inventory: Key Strategies for Publishers

Maximizing Revenue from CTV Inventory: Key Strategies for Publishers

As Connected TV (CTV) consumption grows, so do the revenue opportunities for publishers.

But more screens don’t always mean more money especially if your monetization setup isn’t built for today’s CTV environment.

If you’re a publisher looking to get more out of your CTV inventory in 2025, this blog breaks down what’s working, what’s hurting fill rates, and where the real revenue potential lies.

Why CTV Monetization Isn’t Just Plug and Play  

CTV might sound like this great opportunity. More viewers, longer watch times, and higher CPMs. But in reality, many publishers are leaving revenue on the table.

  • CTV doesn’t work the same way as web or mobile. The tech setup, how people watch content, and the type of formats used it’s all different.

  • Advertisers come in expecting more. They’re looking for top-tier inventory with high viewability, precise targeting, and measurable outcomes.

  • But a lot of that inventory ends up going unused mostly because publishers either don’t have the right setup or aren’t using the best strategy to connect with demand.

Don’t Skip These CTV Setup Essentials in 2025

Let’s start with the fundamentals. Here are a few things every publisher should lock down:

1. Ensure Accurate Ad Declarations

Google and other platforms now require detailed, transparent labeling of your inventory types and placements. If these aren’t clear, demand sources may avoid your inventory.

2. Use the Right VAST Setup

Make sure your VAST tags follow platform specific rules. If ads don’t render properly or if measurement doesn’t work, you’re going to lose out on revenue.

3. Avoid Serving Ads When No One’s Watching

Don’t refresh or serve ads when screens are inactive or the content isn’t actually being viewed. This can lead to policy issues and reduce trust with buyers.

4. Display Ads Without Delay

For DOOH and similar formats, ads must show immediately after the request not minutes later. Ad delays can result in missed impressions and wasted opportunities.

The Real Challenges Publishers Face with CTV Fill Rates

Even when the setup is right, fill rates can fall short. Here’s what we’re hearing from publishers:

1. Mismatch between inventory and demand

Not all demand partners are built for CTV. If you’re relying on partners who primarily buy web traffic, you’re going to have unfilled spots.

2. Poor segmentation

Advertisers want to target by device type, content category, and viewing time. If your data is too general, they’ll skip bidding.

3. Inconsistent performance metrics

Buyers expect viewability, completion rates, and engagement metrics. If those aren’t being passed back correctly or if your video player isn’t optimized you’ll miss deals.

4. Pricing that scares buyers off

Many publishers set price floors too high, hoping to keep CPMs up. But if the floor is unrealistic, buyers don’t bid and inventory stays unsold.

CTV Monetization Strategies That Are Working in 2025

1. Commercial breaks

Breaking long-form content into structured ad pods (like TV commercial breaks) works well. But adding frequency capping and mixing skippable/non-skippable units increases user tolerance.

2. Contextual Targeting at the CTV Level

Without cookies, contextual data is becoming more important. Publishers who categorize shows by genre, mood, or audience type are seeing higher fill rates and CPMs.

3. Interactive Video Ads

Shoppable ads, QR codes, and remote-controlled interactions are delivering better engagement and higher bids from brands that want to drive direct response.

4. Partnering with CTV-Focused SSPs

Not all supply-side platforms are built for CTV. Publishers working with SSPs that specialize in video and OTT are getting more demand and better matching.

How to Keep Your CTV Revenue Growing

Things change fast in CTV, so staying sharp is key:

  • Check your inventory setup often to fix issues and spot new chances to improve.

  • Look at how each demand partner is performing don’t hesitate to try others if things feel slow.

  • Make sure your ad tech is giving you clean, useful data. Buyers want transparency.

  • Organize your content clearly so it’s easier for advertisers to target the right audiences.

  • Watch for updates from Google and major DSPs rules shift, and staying informed helps you avoid surprises.

Final Thoughts 

CTV monetization is no longer just about filling ad slots. It’s about creating a structured, transparent, and performance ready environment that buyers want to invest in.

If you’re not seeing the revenue you expected, you might wanna change your strategy.

Ad Refresh Strategies: Do They Really Boost Revenue?

Ad Refresh Strategies: Do They Really Boost Revenue?

Publishers are constantly looking for ways to make more revenue out of their existing ad inventory without affecting the user experience. Ad refresh is one of the easiest strategies that often comes up in terms of doing that.

The idea is instead of showing a single ad when a user visits you refresh the ad every 30, 60, or 90 seconds. More impressions, more revenue right at least in theory. But is it effective?

Let’s talk about what exactly an ad refresh is, how it can affect revenue and user experience, and whether or not it’s worth adding to your monetization strategy.

What Is Ad Refresh?

Ad refresh is reloading an ad slot after a set amount of time while the user remains on the same page. Instead of the ad staying static, a new ad is served periodically, giving advertisers more chances to show their creatives and publishers more chances to earn.

There are different types of ad refresh:

 Time-based refresh: Ads reload after a fixed time (e.g., every 30,60 seconds).

● Event-based refresh: Ads are refreshed whenever a user clicks or scrolls.

● Active View-based refresh: Ads refresh only when they meet viewability standards.

While the ad refresh can increase the no of impressions the important question is whether or not ad refresh actually results in an increase in revenue and if so, at what cost.

But not all ad impressions are treated the same. Advertisers care about viewability not just the number of impressions.  

If ads are refreshed too quickly or are not actually seen or interacted with they may get lower bids over time hurting your CPM and affecting user experience.

Does Ad Refresh Really Increase CPM?

Yes, but only when done right. When ads are refreshed strategically, publishers can increase viewable impressions and overall revenue.

But if it’s overused or not optimized, it can backfire by reducing CPMs, lowering viewability scores, and even pushing advertisers away.

When Ad Refresh Helps:

● High Page Time

If users stay on your page for a long time like articles, forums, or live scores, refreshing ads after 30-60 seconds can make sense. You are making better use of the screen space because the user is engaged.

● Viewability Based Refresh

Refreshing ads only when they are viewable (e.g., 50% of the ad is on screen for 1 second or more) helps maintain advertiser trust. These impressions are more likely to be monetized at higher rates.

● Demand from the Programmatic Market

When there is a lot of demand from the Programmatic Market, ad refresh can help fill more impressions without making CPMs too low.

When It Hurts:

● Low Viewability

If ads are refreshing in areas users don’t scroll to, or refreshing too quickly, it can lower viewability scores. This is noticed by advertisers.

● Ad Fatigue

Refreshing ads too many times will hurt user experience and lead to higher bounce rates or lower session times.

A good rule of thumb? Keep refresh rates reasonable 30 seconds or more, non-viewable ads should not be refreshed, and the content should remain the primary focus.

● Invalid Traffic Risks

Poorly implemented ad refresh can trigger invalid traffic filters, which can lead to lost revenue or even account suspension.

Google Ad Manager has rules around ad refresh. Not all ad types can be refreshed, and if you’re refreshing ads that shouldn’t be, you risk policy violations or losing access to demand sources.

Data Behind Ad Refresh: What the Numbers Say

According to data from industry platforms, publishers using smart ad refresh (viewability-based, time-controlled) have seen 10% to 30% increases in revenue without major drops in CPM. However, aggressive refresh (e.g., every 20 seconds regardless of viewability) can result in lower fill rates and CPMs by 15%.

According to Ad Manager reports, advertisers value viewable impressions more than volume. Even with fewer total impressions, ads with a high viewability (above 70%) tend to earn higher CPMs.

Best Practices for Ad Refresh

If you’re thinking about trying or optimizing ad refresh, here’s what actually works:

● Refresh Only Viewable Ads

Active View or viewability triggers can be used to refresh ads that are in view. This protects your CPM

● Reasonable Intervals

30 to 60 seconds is a safe zone for most content types. Anything faster increases risks.

● Track Metrics

Pay close attention to metrics like viewability, CPM, and fill rate. If bounce rates go up or CPMs drop, reassess your settings

● Watch User Behavior

Are users leaving faster after Ad refresh is enabled? That’s a red flag.

● Test and Adjust

What works for one site might not work for another. Do A/B tests to discover the optimal balance between revenue and user experience.

● Communicate with Demand Partners

Some advertisers or platforms don’t allow refreshed impressions. Always check policies, especially with premium demand.

● Stay Compliant

Follow Google’s ad refresh policies carefully. Violations can hurt your monetization.

So, Is Ad Refresh Worth It?

It can be if done right. The mistake many publishers make is thinking ad refresh is a magic button for more revenue. It’s not. You need to be strategic, test results, and prioritize user experience.

Publishers who use smart refresh strategies are more likely to see consistent gains, while those who use aggressive or careless settings might see short-term spikes followed by long-term drops.

If your goal is sustainable revenue growth, focus on quality impressions, not just more impressions. Ad refresh is a tool and like any tool, it works best when used with purpose.

How AI is Changing Video Ad Targeting and Monetization

How AI is Changing Video Ad Targeting and Monetization

● Viewing: What types of videos are users engaging with, for how long, and when are they most active?

● Relevance: AI scans the video content so that ad themes align with what the viewer is watching.

● Engagement: It can adjust ad delivery in real time based on actual user engagement with the content to optimize for ad frequency and placement for best results.

Monetization Strategies

AI does not only assist with targeting but also assists publishers with video content monetization, increasing revenue in several key ways:

1. Automated Buying

Manual bidding and campaign adjustment are the things of the past. AI-powered ad platforms Analyze market trends, competition, and historical performance to automatically adjust bids and placements in real time to get that high ROI for advertisers while boosting revenue for publishers.

2. Dynamic Placement

Not all ad placements perform the same. AI helps to determine the best placements for video ads based on real-time tracking of user attention and engagement.If an ad break causes viewers to drop off, AI has the means to adjust placements dynamically to improve retention and revenue.

3. Real-Time

The Growing Role of AI in Ad Buying

AI is taking control of almost every aspect of programmatic advertisement. Ad platforms like Google, Meta, etc are now using machine learning to automate targeting, bidding, and optimization.

While this makes buying ads much more efficient, it certainly introduces several other concerns:

Less control

Since AI will be making decisions, advertisers and publishers will have less control over where ads appear and how budgets are spent.

Transparency issues

Some AI platforms act like “black boxes,” providing few insights into why one ad works better than another.

Privacy regulation

while AI is dependent on working with vast amounts of data, privacy laws such as GDPR are shaping how this technology can be used in advertising.

Despite these challenges, There’s no doubt that AI-based buying is proving itself to be more effective when compared to traditional methods.

It allows for real-time, data-based decisions instead of relying on outdated assumptions.

What’s Next for AI in Video Ads?

AI keeps getting smarter, and everything points to a much more automated and personalized future for video advertising. Here is a few things you can expect:

Hyper-personalized ads

AI will deliver ads that are tailor-fitted to individual users, adjusting everything from messaging to visuals based on their past interactions.

More interactive video ads

Interactive and shop-able ads enabled by AI allow viewers to directly interact with products without leaving the video.

Deeper integration into CTV and streaming

As more switch to Connected TV (CTV), AI will enhance optimizing ad placements and viewer experiences.

Ad agencies are already investing in AI-driven creative tools. For example, WPP has collaborated with Stability AI in an effort to introduce generative AI into ad production allowing brands to develop highly personalized ad content at scale.

Final Thoughts

Video ad targeting and monetization with AI will become more targeted and profitable. With automated media buying, real-time optimization, and smarter ad placements, publishers and advertisers can reduce wasted spend and improve engagement.

Although AI does face some challenges, the benefits far outweigh the risks. The key is to stay informed, experiment with AI-powered tools, Adapt as technology is in a constant state of evolution.

Those who embrace the advances AI has in store for video advertising will find themselves in the best position to drive revenue growth and improved ad experience.

Ad Serving Limits in 2025: What Publishers Need to Know

Ad Serving Limits in 2025: What Publishers Need to Know

If you’re a publisher monetizing content through AdSense or ad platforms,

You likely have come across ad limit at some point. These ad limits can make a difference in your revenue especially if it’s your main revenue source.

We will deep dive into what ad serving limits are why they happen and so much more   

What Are Ad Serving Limits? 

Ad serving limits the number of ads that can be shown on your website or app within a given period. These limits can come from Google AdSense, AdMob, Ad Manager, ad exchanges, or even set by publishers themselves. 

The goal is to keep the user experience smooth and to avoid too many or low-quality ad placements that can annoy users or trigger policy violations. Limits typically focus on things like:

  • Frequency: How often an ad is shown to a single user.
  • Device Based: Ads may be restricted on desktop vs mobile. 
  • Publisher-specific: Some publishers enforce their own stricter controls.

Ad serving limit are designed to protect users from getting bored with ads, stop spamming, and make sure that advertisers get quality impressions.

Why Do Ad Serving Limits Happen?

Google’s systems apply limits for several reasons, especially if there are concerns about invalid traffic, policy violations, or poor user experience. The most typical causes are as follows: 

1. Invalid Traffic

This is the biggest reason for ad limits including any traffic that doesn’t come from real users- bots, accidental clicks, click fraud. If Google detects suspicious traffic patterns, your ad serving may be limited.

2. Policy

If your content or ad placement violates Google’s policies for example, too many ads on a page, misleading content, or interfering ad formats you could face limits.

3. Quality

Google wants to ensure that your content is useful, the site isn’t slow and has clear navigation for users and having too little content can lead to limits.

4. User Experience

If your site is overloaded with ads, or if they’re placed in ways that affect user experience if engagement drops, so does your ability to serve ads.

Ad Serving Limit Types

Account Being Assessed

Google is examining your content and traffic. This could be temporary, and your revenue might decrease during that time.

Invalid Traffic

Google has limited your ad serving after detecting IVT. Until the issue is fixed, these limitations remain in place. 

Placement Limits

Google places restrictions on how many and where advertisements can appear on your pages.

Account Level Restrictions

Google may restrict your entire account from serving ads. This happens when there are repeated or severe policy violations.

How to Handle Ad Limits Effectively

1. Identify the Issue

Check your AdSense dashboard for any alerts. Google typically explains why a limit was imposed. Analyze your traffic sources, check ad placements, and review your content.

2. Address the Cause

  • For IVT: Use tools to block fake traffic, like Traffic Cop or similar services.
  • For policy violations: Fix the problem areas poor ad placement, bad content, or slow load times.
  • Don’t delete and recreate ad units this will not solve the issue.

3. Improve Site Quality

Focus on original, engaging content. Optimize site speed, especially on mobile. Make navigation easy and ads less intrusive.

4. Monitor and Test

Use tools like Google’s Ad Review Center to manage which ads run on your site. Adjust your ad balance settings and avoid placing too many ads on low-content pages.

5. Request a Review

Once changes are made, request a review through your AdSense dashboard. Be concise and provide proof that the issue has been resolved.

Proactive Tips to Avoid Limits

  • Stick to Policy: Always follow AdSense guidelines for ad placement and content.
  • Audit Regularly: Do manual checks of your site for user experience, content quality, and ad implementation.
  • Track Traffic Sources: Know where your visitors are coming from. Sudden spikes from low-quality sources can trigger flags.
  • Improve Content: The better your content, the more likely you’ll attract real, engaged users not bots.
  • Site Performance: Make sure your site loads fast and is mobile-optimized.

Recovering from Ad Limits

If you do hit a limit, stay patient. Resolution times vary. Focus on improving quality and be ready to explore alternate revenue streams in the short term.

Estimate potential losses and take steps to prevent future disruptions. Remember, managing ad serving limits isn’t just about avoiding penalties it’s about maintaining trust with users and advertisers.

If you need help navigating ad monetization, smart strategies, and compliance, working with a team that understands the space can save you a lot of headaches.

Why Some Publishers Earn Higher CPMs and How You Can Too

Why Some Publishers Earn Higher CPMs and How You Can Too

Cost Per Mille has long been one of the most relevant advertising metrics, and it helps to measure the publisher’s revenue from digital advertising. 

While some publishers are able to get consistently higher CPMs, others will find it difficult to get similar rates. Why? This isn’t just luck other things impact the amount advertisers are willing to spend for ad slots.

If you want to increase your CPM, understanding the factors affecting the CPM and using the right strategies can make a big difference. Let’s break it down 

What Affects CPM Rates?

1. Audience Matters More Than You Think

Advertisers are willing to pay premium rates to be able to reach the right audience.

If you have high-earning users, decision-makers, or engaged readers converging in a premium niche like finance, tech, or healthcare, you’ll likely see higher CPMs. Broad, untargeted traffic generally spells lower ad rates.

2. Content Quality & Relevance

Not all content can be equally treated. High-quality, niche-specific content will get better-paying advertisers. 

For example, a website about cybersecurity or an investment strategy has greater value for advertisers than a general entertainment site. If your content targets high demand industries, advertisers will pay more to show their ad.

3. Ad Viewability & Placement

CPMs are dependent on whether your ads are seen by the users. Your CPMs will suffer if ads are placed at the bottom of the page, or if users scroll past them too fast, your CPM will be affected.

Ads that are placed above that fold close to engaging content and in areas where users spend more time, giving ads better visibility and, as a result, higher CPMs.

4. Choosing Your Ad Format

Some ad formats simply pay more. Video ads, rich media, and interactive ads earn higher CPMs than regular display ads and even within display ads, larger and more impactful formats, such as 300×600 or 970×250, outperform smaller banner ads.

5. Geography

The CPMs are determined by the geographic location of your audience.

Traffic from the U.S., Canada, the U.K., and other countries with high GDP will yield a greater return for advertisers than traffic from low-income areas.

If your audience is global, try segmenting your high-value users and optimizing ad delivery for them, boosting your CPMs.

6. Market Trends

The CPMs fluctuate based on demand from advertisers.

For example, in the fourth quarter (holiday season), advertisers spend more which increases your CPMs. Knowing when demand peaks within your industry allows you to adjust your content strategy to maximize the opportunity.

How to Increase Your CPMs

Now that we know what affects CPMs, let’s talk about what you can do to improve yours

1. Improve User Experience & Engagement

Longer session durations and lower bounce rates result in better-performed ad performance.

Make sure to optimize your website for speed, readability, and navigation. If users stay on the website longer, ads will likely get more attention, improving your average CPM.

2. Use Header Bidding

Head Bidding promotes competition for ad inventory by allowing many demand sources to real-time bid for ad space.

This leads to higher CPMs because advertisers are forced to compete rather than being prioritized in a traditional waterfall setup.

3. Experiment With High-CPM Ad Formats

If you are only running display ads, start testing different ad types like video ads, interstitials, or native ads.

These ad types usually have better CPMs, and many advertisers prefer them because of their engagement factor.

4. Optimize Ad Placement 

Place ads in locations that balance both viewability and user experience.

Ads should be visible but not intrusive like in-content placements, sticky ads, and above-the-fold positions that do not interfere with readability. 

5. Diversify your traffic sources

If the majority of traffic comes from low-CPM regions, focus on attracting users in high-CPM countries.

SEO, targeted content marketing, and paid traffic strategies are some of the ways to draw those premium users in.

6. Focus on first-party data and direct deals

With third-party cookies out, the value of first-party data increased for advertisers more than ever.

If you are collecting audience insights (like user interests or behavioral data), you can negotiate direct deals with advertisers who are looking to reach that particular audience.

7. Analyze and optimize 

The ad market is constantly changing what worked a few months ago may not work so well now.

Regularly review your analytics, test different strategies, and make changes based on performance. Small tweaks can add up to significant revenue increases over time.

Final Thoughts

If you want higher CPMs, it’s not just about increasing traffic it’s about getting the right traffic, optimizing the ad placements, and utilizing high-paying ad formats. 

Publishers who focus on audience quality, strategic ad implementation, and continuous optimization will see better CPMs than those who dwell on generic content and outdated monetization strategies. 

Try these strategies today, and you will see the outcome in your CPM rates and overall ad revenue.

Interstitial vs Banner Ads: Which Earns Higher CPMs?

Interstitial vs Banner Ads: Which Earns Higher CPMs?

In digital advertising selecting the right ad format can play a very important role in maximizing revenue from various options to choose from interstitial and banner ads are two common ad formats with their features and effects on user experience and earnings. 

We will be doing in-depth interstitial and banner ad breakdowns to find out what formats generate more revenue and how publishers can use them to maximize revenue.

Understanding Interstitial Ads

These are full screen ads that appear at points, such as between game levels or while navigating between content sections.

Compared to standard ad formats these ads are immersive and are designed to engage users and capture their full attention.

Features of Interstitial Ads:

  • These ads are full screen, removing all other distractions and keeping user attention only on the advertisement.
  • By aligning with the user’s navigation flow during transitions, like in between games or content they aim to minimize disruption.
  • These can be in images, videos, or interactive content, offering a rich media experience.

Understanding Banner Ads

These are static or animated ads that appear on either the top, bottom or next to the content but these ads are less effective in capturing user attention they can blend in without interfering with user experience.

Features of Banner Ads:

  • These ad sizes are 728×90 and 300×250 pixels These are responsive ads that work with different screen sizes.
  • You can place them between content this lets users engage without interrupting their experience.
  • Simple to create and easy to place making them a popular choice for publishers and advertisers.

Comparison of CPMs: Interstitial vs Banner Ads

Cost Per Mille (CPM) is the revenue per 1,000 ad impressions.

The CPM between interstitial and banner ads differs in price because they have different engagement levels and responsiveness based on the user experience offered.

Interstitial Ads CPM:

Based on studies interstitial ads have higher CPM than banner ads.

Research shows that interstitial ads outperform banner ads by an average of more than 4,000%.

The difference is that fullscreen interstitials command better engagement from users and higher click-through rates. 

Banner Ads CPM:

Banner ads have lower CPMs because they are less intrusive and one disadvantage of these is users either consciously or subconsciously ignore banner ads.

The average CPM for banner ads in the US is around $0.60 for Android and $0.27 for iOS.

Factors that Affect CPM

Many factors are responsible for impacting the CPM rates of interstitial and banner ads.

1. Engagement:

These ads are more immersive with a higher engagement rate leading advertisers to pay premium rates

2. Placement and frequency:

Higher CPM for interstitials, but the user experience suffers if too many ads appear on the user feed which could lead to uninstalling apps or leaving websites.

Whereas banner ads can be shown more frequently and are less intrusive they earn less per impression.

3. Location:

CPMs vary based on location. The USA and Europe generally offer a higher CPM because of increased competition for ad space.

4. Quality:

High-quality, relevant ads to the target audience can command better CPMs, regardless of format.

Strategies for Maximizing Revenue

1. Use both Ads:

Find a balance so you take advantage of both ad formats.

Use interstitial ads at natural transition points to maintain user experience, and use banner ads so you can still maintain ad visibility without affecting user experience.

2. A/B Testing:

Test different ad placements, frequency, and formats to find the right combination of both ad formats ensuring a good user experience.

Analyse user engagement and revenue metrics to make informed decisions. 

3. Focus on user experience:

Prioritize user experience ahead of any aggressive ad rollout; ensure that interstitial ads have exit options and that your banners do not obscure content.

4. Optimize Location:

Adjust ad strategies based on regional performance data, allocating premium ad formats to high-CPM regions to maximize earnings.

5. Focus on Quality:

Focus more on delivering high-quality ads that align with user interests, increasing the chances of interaction and conversion.

Conclusion

Interstitial and banner ads have different benefits and challenges. Interstitial ads provide higher CPMs due to immersive transitions but must be used in a way you don’t affect user experience.

Banner ads provide steady revenue without affecting user experience but have low CPM.

Publishers could maximize user engagement and ad revenue by combining both ad formats and continue to optimize for performance

Should You Use Waterfall or Header Bidding? Choosing the Best Ad Strategy for 2025

Should You Use Waterfall or Header Bidding? Choosing the Best Ad Strategy for 2025 

With the changes in the digital advertising landscape, the way publisher sells their ad space is continuously changing and choosing the right strategy is key to maximizing revenue.

Two common methods are Waterfall Bidding and Header Bidding. 

Publishers need to understand these methods in detail as they look into maximizing their ad monetizing strategies.

Understanding Waterfall Bidding

Waterfall vs. Header Bidding

A method where the ad inventory is offered to different ad networks in a fixed order allows publishers to prioritize ad networks that have delivered the highest yield in the past. 

If the top-tier network cannot fill the inventory, it moves to the next, and so on, until the ad space is filled or all options are exhausted. 

Advantages 

Simplicity: The waterfall model is easy to implement, making it easier for publishers with limited technical resources to use.

Control: Publishers can choose which ad networks to prioritize, giving them some control over which advertisers appear on their platforms.

Disadvantages 

Revenue: If a low-tier ad network offers a higher bid, it will be discarded because the requests never reach them.

Loading Time: Since the process moves one step at a time it ends up delaying ad loading and impacting user experience.

Understanding Header Bidding?

It’s more advanced than the waterfall bidding instead of sending one request at a time, all ad networks get to bid at the same time and the highest bid wins leading to higher CPM. 

This allows publishers to maximize their ad revenue by only accepting the highest bid.

Advantages

Revenue: By having multiple bidders at the same time, Publishers can get the highest bid, maximizing their ad revenue.

Transparency: Publishers see all bids and know how much their inventory is worth.

Higher Fill Rates: Having more bidders means ad spaces are more likely to be filled.

Disadvantages 

Technical Setup: Header bidding demands technical expertise, such as implementing JavaScript code into the website and managing several demand partners.

Slow Page Speeds: Header bidding will increase the average revenue per ad impression but if not optimized too many bids at once can affect page loading speed.

Waterfall vs Header Bidding: Which One Is Better?

Which Ad Strategy Should You Use in 2025?

Choosing between waterfall and header bidding depends on a few things

If you have a technical team and you’re looking to maximize your revenue header bidding is a better option.

If you want a method that’s easier to set up and requires less technical expertise waterfall method is a better option.

If page speed is a concern, optimize your header bidding setup for better performance.

Final Thoughts

In 2025, header bidding is becoming the method of choice due to higher revenue potential and efficiency, but small publishers or those who do not have a tech team may still prefer waterfall bidding due to its ease of use. 

The key is to test both to find out which method performs best for your ad inventory.
