AdGuard Filter Policy
When discussing Adguard ad filters, there is often one topic that causes disputes – whether shall Adguard block this or that ad. By framing the rules we stick to special criteria. Now it’s time to publish them. Our criteria are much similar to EasyList Policy, which we find correct and appropriate. Nevertheless, we have put changes to some points.
Ad filters
Those are actually language filters, including: Russian, English, German, Dutch, Spanish, Portuguese, Japanese.
What shall these filters block?
- The filters shall block ads everywhere possible.
You can find the definition of “ad” right here. - Ads shall be blocked regardless of reasons and goals of such ad.
- We will block ads caused by malicious apps or extensions that inject ads. Please note that we do it only on condition that you will specify how to install this app or extension.
Limitations and Exceptions
If a rule is subject to the list of limitations described below, then it won’t be added to main filters.
- Websites’ own ads are not to be removed on purpose. On the other side it shouldn’t be unblocked, because such unblocking can cause displaying of third-party ads.
- Rules that are specific to the particular website will be added only if the website has sufficient traffic.
Traffic is determined by open statistics (if it has such) or in other ways.
Website’s traffic is considered sufficient when it has 30 thousands visitors a month. - Anti-adblock scripts will be blocked only if they limit functionality of the website or
interfere in its use. - Rules that often cause problems with work of some websites will be deleted.

Quality requirements for filtering rules
