AntiAdBlock Core is an anti adblock script for publishers: it detects visitors who use an ad blocker and asks them to allow ads, so the site recovers lost ad revenue. Self-serve, with flat public pricing and a free plan.

How it works

- Multi-signal detection with 99.7% precision, retrained daily and kept current against the major filter lists, with nothing for you to update.

- Visitors with an ad blocker see a notice asking them to allow ads, with step-by-step instructions for their blocker. One click checks again on the spot.

- The notice speaks your visitor's language (English or Spanish) on its own.

- From signup to first detection in about a minute.

First-party delivery

The script can be served from a subdomain of your own domain, the setup we recommend for maximum detection. Included in every plan, the free one too.

Blocklist Watch (from Pro)

We read the ad blocker filter lists every day and show you, in plain language, when one of them names your domains. On Max and Business you can send the case to our team with one click.

Detection API (Max and Business)

Detection without our notice: your own code decides what to do when a visitor blocks ads.

Dashboard

Every plan gets the live overview: detections, recoveries, recovery rate and estimated revenue at your CPM, plus its own counter for network-level (DNS) blocking. Max and Business add detailed analytics by block type, device, browser and country.
