Google asks publishers if it can use first-party cookies on their websites

Google this month started asking publishers if it can use first-party cookies on their websites. Google may use first-party cookies when third-party cookies are not available.

The control is available since this week, but Google says the choice won’t affect ad serving until October 16.

If browsers limit the third-party cookies, and a publisher decides to not enable Google’s first-party cookies, all advertising with frequency cap will not enter on the publisher’s auction. So the publisher’s revenue can drop if they don’t allow Google to use first-party cookies.
