Sometimes an advertising cookie may be set on the domain of the site you’re visiting.
In the case of our Double Click product, a cookie named ‘__gads’ may be set on the domain of the site you’re visiting.
If you don’t want the ads you see to be coordinated across your devices, you can opt out of interest-based advertising using Ads Settings.
Google Analytics is Google’s analytics tool that helps website and app owners to understand how their visitors engage with their properties.
It’s generally set in the domain (you can find a list of domains we use for advertising cookies at the foot of this page).
The main cookie used by Google Analytics is the ‘__ga’ cookie.
Conversion cookies are not used by Google for interest-based ad targeting and persist for a limited time only.
A cookie named ‘Conversion‘ is dedicated to this purpose.
Some common applications of cookies are to select advertising based on what’s relevant to a user; to improve reporting on campaign performance; and to avoid showing ads the user has already seen.
