Criteria


To ensure transparency and fairness, the following rules have and will always apply to everyone without exceptions:

  • Participants cannot pay to avoid the criteria. Every ad has to comply with the criteria.
  • For transparency reasons, we add all Acceptable Ads to our forum to provide our community with the opportunity to submit feedback. We greatly value feedback and read all comments.
  • Adblock Plus users are valuable to us and we listen to them. If, for valid reasons, any Acceptable Ads proposal is rejected by our community, the ad(s) will be removed from our whitelist.

We are able to keep our open source product free by charging large entities a fee for whitelisting services. For the other 90% of our partners, these services are offered free of charge.

Placement

Acceptable ads criteria placement

Ads must not disrupt the user's natural reading flow. Such ads must be placed on top, side or below the Primary Content. 1


  1. The 'Primary Content' is defined as (based on Mozilla's description of the <main> HTML element): The Primary Content consists of content that is directly related to, or expands upon the central topic of a document or the central functionality of an application. This content should be unique to the document, excluding any content that is repeated across a set of documents such as sidebars, navigation links, copyright information, site logos, and search forms (unless, of course, the document's main function is a search form). 

Distinction

Acceptable ads criteria label

Ads should always be recognizable as ads and distinguishable from all other content (e.g. are not hiding the label, are not misleading users into thinking an ad is part of the primary content). Ads should be clearly marked with the word "advertisement" or its equivalent.

Size

Acceptable ads criteria percentage

Individual ad-size requirements depend on the placement of the ad:

  • When placed above the primary content, the maximum height of an ad should be 200px.
  • When placed on the side of the primary content, the maximum width of an ad should be 350px.
  • When placed below the primary content, the maximum height of an ad should be 400px.

Ads must always leave sufficient space for the Primary Content on the common screen size of 1366x768 for desktop, 360x640 for mobile devices and 768x1024 for tablets. 1 2 3

All ads that are placed above the fold (the portion of the webpage visible in the browser window when the page first loads under the common screen size) must not occupy in total more than 15 percent of the visible portion of the web page. If placed below the fold, ads must not occupy in total more than 25 percent of the visible portion of the webpage.
