A publication for better filtering decisions

AdBlockList.com is an independent educational resource for people exploring ad block lists and the systems around them. Ad Block List Lab brings together long-form guides on browsers, domain formats, API design, AI scoring, bot controls, and measurement.

Our starting point is a practical question: what can you observe, what can your chosen tool control, and how will you know whether a change helped? A specific, repeatable answer is more useful than a broad promise to block everything.

For browsers, builders, and publishers

If you browse, begin with the ad block list fundamentals and the guide for your browser. If you build integrations, explore data contracts and safe updates. If you publish content, start with crawler instructions and publisher controls.

These audiences sometimes use the same words for different mechanisms. We keep those differences visible so that a browser request rule is not mistaken for a server access control, and a classification score is not mistaken for a guarantee.

How to read the Lab

Each Lab article links to one directly relevant primary reference. The surrounding explanations develop practical workflows, comparisons, and questions. Examples are identified as illustrative when they describe proposed systems or fictional records.

We avoid invented performance figures, credentials, testimonials, and product partnerships. A premium label does not establish data quality; an AI label does not establish accuracy. Conclusions should be limited to the evidence available.

What the site provides

The site provides guides and articles. It does not offer an AdBlockList.com extension, a hosted API, a trained scoring model, a live scraper feed, or paid list inventory. Browser names identify the subject of independent coverage, not a partnership or endorsement.

The buying guides help readers formulate evaluation criteria. They do not quote prices, collect payment, or replace the need to examine a supplier’s actual terms and deliverables.

Help improve an explanation

If a factual point is wrong or a source has changed, send a correction with the page URL, the passage at issue, and a directly relevant reference. If a guide is unclear, tell us what you were trying to understand.

Do not include credentials, browsing histories, private customer data, or unredacted request logs. A concise description and reproducible, non-sensitive example are usually a better starting point.
