AdSense Ad serving settings

You can control certain ad format and auction behaviors in AdSense, such as blocking user-based ads, or allowing additional ad technology vendors in your account.

Personalized ads

User-based ads

Choose whether or not you want to display ads that are based on users’ interests, demographics, and Google Account information. Note that you can’t opt out of remarketing.

Additional ad technology vendors

Google allows third party vendors used by advertisers to buy your ad slots. Allowing additional ad technology vendors will result in more ads being eligible to be shown to your users, and as a result can potentially lead to higher earnings.

Note: This control doesn’t override EU user consent, the California Consumer Privacy Act or other regulatory settings, or the list of allowed ad networks in your account. For more information, see:

Allow first-party cookies on your site

Choose whether or not you want to allow first-party cookies from Google on your site.

Cookies are small text files downloaded to a user’s browser that can be used to store user information and preferences.

Cookies are either first-party (associated with the domain the user is visiting) or third party (associated with a domain that’s different from the domain the user is visiting). Google may use first-party cookies when third-party cookies are not available.

Allowing first-party cookies from Google may increase your revenue because it enables features like frequency capping on ads and allows ads with a frequency cap to serve on your site.

Display ads

Similar-sized display ads

Choose whether or not you want to show similar-sized but higher performing display ads in your ad units. To help increase competition for some ad sizes, AdSense will occasionally modify similar-sized display ads to fit within the ad units.

When this happens, the modified ad is served neatly centered at the top of the ad unit. For example, you might see a 468×60 ad in a 320×50 ad unit.

Animated display ads

Choose whether or not you want to show non-static display (e.g., image) ads, such as ad creatives created using Adobe Flash or animated GIF formats.


Choose whether or not you want to display interactive VPAID video ads. VPAID is a standard that allows advertisers to create interactive video ads, e.g., overlays, galleries, etc. Note that this control does not apply to non-VPAID interactive video ads, e.g., TrueView video ads.
