First-party cookies from Google

You can now choose whether Google can use first-party cookies on your site. 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.

We've added a new control to the "Ad serving" tab in your account to let you choose whether you want to allow first-party cookies. To access the control, click Blocking controls All sites Ad serving. The control is available from today but your choice won't affect ad serving until October 16, 2020.
