Google AdSense has a new feature to enable you to now choose whether Google can use first-party cookies on your site. Google said it may use first-party cookies when third-party cookies are not available.
Google said if you allow first-party cookies it "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."
Google has added a new control to the "Ad serving" tab in your AdSense account to let you choose whether you want to allow first-party cookies.
This new control is available today but Google said "your choice won't affect ad serving until October 16, 2020."
Google's help document said:
