If your videos are funded by ads, you have an invisible leak: every viewer running an ad blocker watches your content, burns your bandwidth, and pays you nothing. The ads never load, the impression never counts, and you never find out — the viewer just quietly watches for free.
For an ad-supported video business, this isn’t a rounding error. It’s a permanent, growing hole in your revenue.
The scale of the problem
Ad blocking is mainstream. On many sites, 15–40% of viewers run a blocker like AdBlock, uBlock Origin, or Adblock Plus. And in markets where the browser itself ships with a built-in blocker — most notably Cốc Cốc in Vietnam, which blocks ads by default — the share is even larger.
Every one of those sessions is pure cost to you:
- You pay for the bandwidth to stream the video.
- You pay for the storage and encoding.
- You earn zero ad revenue in return.
The more successful your content is, the bigger this loss grows. It scales against you.
Why you can’t just ignore it
Some creators assume ad-block users “wouldn’t have clicked anyway.” That misses the point. These viewers are consuming your most expensive resource — video bandwidth — while contributing nothing to the business that pays for it. On a large library, that’s real money leaving every single day.
Worse, you can’t even see it clearly in your analytics: the ad simply never fired, so it looks like the viewer watched a “free” video. The loss is silent by design.
AVCaption’s answer: Adblock Protection
AVCaption includes a built-in Adblock Protection feature that closes this leak. When enabled on a video, AVCaption detects whether the viewer is running an ad blocker. If they are, playback is paused and the viewer sees a polite message asking them to disable their ad blocker and reload to continue watching.
The result is simple and fair:
- Ad-blocked viewers turn off their blocker → your ads load → your revenue is restored.
- Or they choose not to watch → you stop paying bandwidth to serve them for free.
Either way, you stop bleeding money on viewers who were never going to pay you back.
It respects the honest value exchange every ad-funded creator relies on: free content in exchange for viewing ads. This is the same approach major publishers use — and now it’s a one-click toggle for your videos.
How well does it work?
Detection reliability by browser / blocker:
| Ad blocker | Detection rate |
|---|---|
| Cốc Cốc (built-in blocker) | ~95–99% |
| AdBlock / Adblock Plus (Chrome, Edge) | ~95% |
| Brave Shields | ~90% |
| uBlock Origin | ~85–90% |
| DNS-level blockers (AdGuard DNS, Pi-hole) | limited |
Overall, ~90–95% of ad-blocked sessions are caught — and for Cốc Cốc specifically, coverage is near-total, which matters enormously for Vietnamese audiences where Cốc Cốc’s default ad blocking is a leading cause of lost video revenue.
Built for how you actually publish
Adblock Protection isn’t a blunt instrument:
- One simple switch. Turn it on once in your Player Settings and it protects your videos — no per-video busywork.
- Never interrupts clean viewers. Anyone without an ad blocker watches normally, uninterrupted. Only ad-blocked sessions ever see a message.
- Works on your own site too. Embedding AVCaption videos on your website with your own ad networks? Adblock Protection covers those as well.
- Zero setup. No technical configuration, no API keys, no code. Just a toggle in Player Settings.
