3. Ad Formats, Placements, and Guidelines

All sites must comply with the following guidelines:

3.1 For Native Ads

Any native ad formats displayed on your Site must be clearly marked as an ad. Native ads must be clearly distinguishable from the rest of the Site’s content and include clearly visible text that reads “Promoted,” “Sponsored,” “Ad,” or a localized version thereof. In line with industry self- regulatory guidance provided by the Digital Advertising Alliance (DAA), Criteo requires that all native ads display the AdChoices or similar privacy information icon and click region linking to Criteo’s privacy policy. The icon must be at least 20x20px and can be placed in any one of the four corners of the ad.

Ads should not be placed very close to or underneath buttons or any other object such that the placement of the ad interferes with a user’s typical interaction with the Site content or functionalities. In particular:

3.3 Pop-up Ads, Prohibited Interstitials and Other Disruptive Ads

Publishers must not display ads in a way that is confusing or disruptive to the user experience, including, but not limited to:

Sticky footer ads “stick” to the bottom of the mobile page, regardless of whether the user is scrolling the page. Publishers may use sticky footer ads only if they comply with the following constraints:

3.5 Incentivised or Rewarded Clicks

3.6 For Video Ads


4. Additional Guidelines Specific to Mobile Apps

4.1 Ad Density

Apps must not display ads that take up more than 30% of the vertical height of the content portion of the screen. The 30% rule applies to “sticky” ads and in-line ads, and full-screen scroll-over ads (ads that require the user to scroll through the ad to view content). Exceptions are permitted for interstitial ads if they comply with Criteo’s guidelines for interstitial ads.

4.2 Apps Permissions, Apps Outside of Official Stores

4.3 Lockscreen Ads, Screensaver Ads, and Ads Running Outside of an App Environment

Unless the Site is an app that is explicitly advertised as a lockscreen utility, Publishers may not display ads on the lockscreen of the user’s device or otherwise employ features that monetize the lockscreen.

4.4 Acceptable Interstitials (In-App Only)

In-app interstitial ads are full-screen ads appearing at natural app transition phases such as when pausing a game, before or after displaying the results of a game, or between two different activities inside the app.

App Publishers may use interstitial ads only if they comply with the following:

4.5 Close-button Guidelines

Certain ad formats such as sticky-footers or interstitials (in-app) require the display of a clear and identifiable close button to dismiss the ad. Criteo prohibits any mechanism that would delay the display of the close-button such as countdowns. Small close-button, absence of close- button or misplacement of the close-button which interferes with the ability of users to close the ad, are prohibited no matter the channel or environment.

The close button must be displayed following the guidelines below:

6. Transparent Supply Chain

Criteo is committed to providing a safe and transparent ecosystem to our advertising clients and publishers alike. We support industry initiatives such as IAB (International Advertising Bureau) ads.txt and app-ads.txt that aim to improve transparency of the supply chain in programmatic advertising.

Our publishers must implement ads.txt and app-ads.txt by correctly declaring sellers (they work with and authorize to sell their inventory) in their ads.txt and app-ads.txt files.

Criteo will reserve its right to automatically filter traffic flagged as unauthorized through our monitoring systems.
