6 CTV Monetization Mistakes That Are Holding Back Your Revenue
The small issues you’re ignoring could cost you serious revenue this year.
If you’re already monetizing Connected TV (CTV) at scale, here’s the hard truth: the landscape is shifting fast and most publishers aren’t keeping up. What worked even a year ago from timeout settings to platform targeting might already be limiting your CTV monetization potential.
This post breaks down the most common setup issues holding back revenue and what high-performing teams are doing differently.
Here’s a tactical breakdown of the biggest performance killers we’re seeing right now across CTV stacks and what advanced publishers should fix next
Why Most CTV Advice Falls Short
The average CTV “how-to” still focuses on macro trends: growing viewership, cord-cutting stats, or vague promises of high CPMs. That’s not useful if you’re already running inventory through Google Ad Manager, using Prebid, or managing line items across multiple platforms.
The questions that actually matter look more like this:
- Why is Roku performing 20% better than Fire TV on the same demand stack?
- Why do your mid-roll ads only fire on 60% of eligible streams?
- Why is your GAM report showing high CPMs but stagnant overall revenue?
These are the questions we’ll answer here and they all point back to weak spots in your CTV monetization strategy.
1. Short Timeout Settings Are Hurting Your Fill Rate
What’s happening:
CTV isn’t mobile. Many publishers still apply short ad timeouts (1–2s) across their CTV inventory — too short for many DSPs to respond, especially on slower devices.
Example:
An Android TV app using a VAST tag in GAM with a 2s timeout. Bidders respond in 2.5s. Result? No fill, no revenue.
Fix it:
- In Google Ad Manager, set VAST timeout = 3.5–4s
- In Prebid Video config, set timeout: 4000ms
- Use Chrome DevTools or Charles Proxy to measure partner response times
For a full list of supported tag settings and parameters, see Google’s VAST ad tag guide.
This simple change can improve fill rate without adding any new demand sources and significantly help your CTV monetization performance.
2. Tracking All Platforms as One? You're Missing Device-Level Problems
What’s happening:
Roku, Fire TV, and Android TV all behave differently. But many publishers still track them under one line item or placement.
That gives you blended data, which hides problems.
Example:
Your Roku fill rate is 85%, but Fire TV is dragging it down to 64%. Your GAM average looks fine but you’re under-serving Fire TV and missing demand.
Fix it:
- Break out your ad units in Google Ad Manager by platform
- Use custom key-values like platform=roku, platform=firetv via your SDK
- Segment your reports by device and platform not just by content or channel
This gives you more control over platform-level optimization a crucial factor in accurate CTV monetization reporting.
3. Mid-Rolls Keep Getting Skipped? Here’s What’s Really Happening
What’s happening:
Your player logs say mid-rolls are scheduled. But in practice, half of them don’t fire. This isn’t always a demand issue it’s a playback issue.
Example:
Mid-roll set at 5:00. User buffers at 4:55, resumes at 5:02. Mid-roll cue missed. No ad served.
Fix it:
- Switch to dynamic cueing based on actual playhead time, not static markers
- Use players like Bitmovin or THEOplayer with reliable ad event tracking
- Monitor ad cue firing through player logs or Logcat on Android TV
Even with available demand, missed mid-rolls = lost revenue.
4. Your Header Bidding Stack Isn’t Built for CTV
What’s happening:
Prebid.js works great for web. But many CTV wrappers don’t support video ad types properly or fail to fire on native CTV environments.
Fix it:
- Use Prebid Server or an updated Prebid.js build with CTV support
- Ensure config includes: mediaTypes.video.context = “instream”
- Run Charles Proxy to check that all bidders are receiving valid CTV video bid requests
- Check OpenRTB fields: placement=2, minduration, maxduration, and skip
If your bidding logic isn’t firing correctly, you’re just filling with the fastest not the highest and that directly impacts CTV monetization.
5. Why You’re Seeing Unfilled Impressions Despite Available Demand
What’s happening:
Google Ad Manager doesn’t always prioritize fill. It optimizes for yield. Sometimes it will skip filling an impression entirely if expected CPMs don’t meet a threshold even if there was demand.
Fix it:
- Create house fallback line items with guaranteed delivery to backfill missed impressions
- Monitor your Unfilled Impressions report and sort by Line Item Priority
- Avoid setting aggressive floor prices unless you have the bid data to justify them
Unfilled impressions aren’t always due to lack of demand they’re often a configuration issue affecting your CTV monetization bottom line.
6. Missing Fields in Your Bid Request? That’s Blocking Demand
What’s happening:
Some DSPs won’t even enter an auction unless specific fields are included in your bid request and many SDKs don’t send these by default.
Example:
A major DSP requires ifa, app.bundle, and device.make. You’re missing one? They ignore the request.
Fix it:
Make sure your ad request includes:
- ifa (Identifier for Advertisers)
- app.bundle or app store ID
- device.make and device.model
- content.genre, channel, or category if available
- Use Postman or cURL to inspect the full bid payload
- Ask your demand partners for a current CTV bid spec checklist
These silent drops in bid participation are invisible but can chip away at your CTV monetization over time.
What to Fix
If you’re operating at scale and want to future-proof your CTV monetization, here’s where to focus:
- Increase ad timeouts to prevent valid bids from being missed
- Split inventory by platform to spot device-specific issues
- Audit mid-roll execution and switch to dynamic cueing
- Use a Prebid stack that supports CTV properly
- Check GAM reports for unfilled inventory trends
- Confirm your bid requests pass all required metadata
These fixes don’t require new partners or major integrations just better use of the systems you already have.
