Cookies Dropped

This checks if the ad tag drops any cookies, particularly third-party cookies.

Why do we test it?

Many browsers and platforms now limit or block third-party cookies for privacy reasons. Ads that drop too many cookies, or non-compliant cookies, may face restrictions or reduced performance.
