AdGuard Ad Filters

Introduction

This article is about the filters we create to use in AdGuard and other ad-blocking software (e.g., uBlock Origin). Filters are sets of rules in text format used by AdGuard apps and programs to filter out advertising and privacy-threatening content such as banners, pop-ups, or trackers. Filters contain lists of rules based on their purpose. Language filters include rules for corresponding language segments of the Internet (e.g., the German filter). Task-based filters group rules that fulfil a specific task, such as the Social media filter or the Tracking Protection filter. Enabling or disabling a filter makes it easier to work with the entire list of rules at once.

Suggest Filtering Rules

You will find many open issues in the GitHub filter repository. Each one refers to a problem with a website, such as a missed ad or a false positive. Pick one of them and suggest your own rules in the comments. AdGuard filter engineers will review your suggestions and, if approved, your rules will be added to AdGuard filters.

Here is the official documentation on the syntax of AdGuard filtering rules. Please read it carefully; it will help you create your own filtering rules.
