Anti-adblock for video and VOD sites
Catch the blocker before the player loads, not after the ad fails.
For video and VOD sites, the highest-value inventory is the pre-roll and mid-roll slot. It is also the single most targeted format by ad blockers, which makes blocked video ads the number-one revenue leak in the category.
Timing is everything. If you only learn a visitor is blocking ads after the player has tried and failed to serve a pre-roll, it is already too late to respond gracefully. AntiAdBlock Core moves detection ahead of the player.
The ad-block problem in your vertical
Pre-roll is your best inventory and the easiest to block
Video ad slots carry the highest CPMs you sell, and ad blockers strip them first. The format that matters most is the one losing the most fill.
Detecting too late breaks the viewing experience
If a blocker is only spotted after a failed ad call, the player has already stalled or skipped. The viewer gets a broken moment and you get nothing in return.
Chrome's MV3 shift changed how video blocking behaves
Manifest V3 reworked how blockers operate, and uBlock Origin Lite handles requests differently from the classic extension. A detector that ignores MV3 misses a growing slice of blocked playback.
How AntiAdBlock Core solves it
AntiAdBlock Core runs its 11-vector detection from an async tag that fires before your video player initialises. Knowing a visitor blocks ads ahead of the first ad call means you can adjust the experience cleanly: show a recovery overlay, swap the playback flow, or message the viewer before the pre-roll ever stalls.
The engine is explicitly MV3-aware, with documented coverage of uBlock Origin Lite in Basic, Optimal and Complete modes alongside uBlock Origin, AdBlock Plus, AdGuard, Brave Shields and Ghostery. Nightly retraining keeps detection current as blockers evolve, and the recovery overlay is fully customizable to fit a video-first layout.

Frequently asked questions
Can it detect a blocker before my video player loads?
Yes. The async detection tag fires before player initialisation, so you know a visitor blocks ads ahead of the first pre-roll call and can respond before playback stalls.
Does it handle Chrome MV3 and uBlock Origin Lite?
Yes. Detection is explicitly MV3-aware and documents coverage of uBlock Origin Lite in Basic, Optimal and Complete modes, which matters because MV3 changed how video ad requests are blocked.
Does it work with my existing video player and ad tags?
Yes. AntiAdBlock Core is a detection layer and does not replace your player or ad server. It simply tells you, early, whether a visitor is blocking so your player flow can react.
