The Acceptable Ads Standard

Every ad has to comply with the Acceptable Ads Standard, and participants cannot pay to avoid the criteria. eyeo acts on behalf of the Acceptable Ads Committee to enable publishers, ad networks, and ad-tech providers to participate in Acceptable Ads, and to enforce compliance with the criteria.

For transparency, all Acceptable Ads are added to a public forum to allow the Internet community the opportunity to submit feedback.

Users’ perspectives are important to us. If, for valid reasons, any Acceptable Ads proposal is rejected, the ad(s) will be excluded and thus not shown to ad-blocking users.

Large entities pay a fee for eyeo’s services, which means participation in Acceptable Ads remains free for approximately 90% of participants.

Placement, distinction, and size

Acceptable Ads must comply with the following criteria to be shown to ad-blocking users.

01 Placement

Ads should not disrupt the natural reading flow. They should be placed above, beside or below the Primary Content1.

1 The 'Primary Content' is defined as (based on the WHATWG Specification'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).

Specific criteria

01 Text ads

Text ads designed with excessive use of colors and/or other elements to grab attention are not permitted.

02 Image ads

Static image ads may qualify as acceptable, according to an evaluation of their unobtrusiveness based on their integration on the webpage.

03 In-feed ads

For ads in lists and feeds, the general criteria differ depending on:

PLACEMENT REQUIREMENTS

Ads are permitted in between entries and feeds.

SIZE REQUIREMENTS

In-feed ads are permitted to take up more space, as long as they are not substantially larger than other elements in the list or feed.

04 Search ads

For search ads—ads displayed following a user-initiated search query—the criteria differ depending on:

SIZE REQUIREMENTS

Search ads are permitted to be larger and take up additional screen space.

05 Ads on pages with no Primary Content

Only text ads are allowed. For webpages without any Primary Content (e.g. error or parking pages), the criteria differ depending on:

PLACEMENT REQUIREMENTS

No placement limitations.

SIZE REQUIREMENTS

No size limitations.

06 Mobile ads

PLACEMENT REQUIREMENTS

  • Static ad types (e.g. 6x1 banner and 1x1 tile ad) are allowed to be placed anywhere on the mobile page.
  • Small ads (6x1 banner or smaller) are allowed to be placed as a sticky ad on the bottom of the screen. Other formats are not allowed to stick.
  • Large ad types (e.g. native tile ads) are only allowed to be placed under the Primary Content.12

SIZE REQUIREMENTS

Ads showing on mobile screens are bound to the following size restrictions:

  • Ads implemented on the scrollable portion of the webpage must not occupy in total more than 50 percent of the visible portion of the webpage.3
  • Ads implemented as a ‘sticky ad’ have a maximum height restriction of 75px (or 15%).
  • Below the Primary Content, ads are limited to 100% of the screen space.4

ANIMATIONS

Animations are allowed for the 6x1 ad type when placed as a ‘sticky’ ad on the bottom of the screen. Animations have to comply with the LEAN standard for animations, and a close button or some other closing mechanism must be included.5

07 Other Acceptable Ad formats?

Are your ads displayed on alternative screens, or are you convinced that you have an innovative Acceptable Ads format that doesn't fit the ads outlined above? Let us know!

Large ad: any ad >300px height
2
The 'Primary Content' is defined as (based on the WHATWG Specification'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).
3
The visible portion of the webpage is defined as a standard CSS pixel size of 360x512px (Samsung Galaxy S7 with the SBrowser), which is based on the standard viewport of 360x640px, but with the OS- and browser UI elements deducted.
4
This means that users can scroll past the primary content and an ad unit served after it can take up the whole screen; but following this ad unit, additional ads cannot be implemented.
