Sometimes a cookie may be set on the domain of the site you are visiting. In the case of our DoubleClick product, a cookie called ‘__gads’ may be set on the domain of the site you are visiting.

Google also uses conversion cookies whose main purpose is to help advertisers determine how many times people who click on their ads end up purchasing their products. These cookies allow Google and the advertiser to determine that you clicked the ad and later visited the advertiser site. Conversion cookies are not used by Google for interest-based ad targeting and persist for a limited time only. These cookies are generally set in the googleadservices.com or google.com/ads domain. Conversion cookie data may also be used in combination with your Google account to link conversion events across different devices you use. Only anonymous conversion data gathered from these cookies is shared with advertisers.
Some of our other cookies may be used to measure conversion events as well. For example, DoubleClick and Google Analytics cookies may also be used for this purpose and may be set in the domain of the site you are visiting.
