A cookie, also known as an HTTP cookie, web cookie, or browser cookie, is a small piece of data sent from a website and stored in a user’s web browser while a user is browsing a website. When the user browses the same website in the future, the data stored in the cookie can be retrieved by the website to notify the website of the user’s previous activity.
What cookies do we use?
Google Analytics is Google’s analytics tool that helps website and app owners to understand how their visitors engage with their properties. It may use a set of cookies to collect information and report website usage statistics without personally identifying individual visitors to Google. The main cookie used by Google Analytics is the ‘__ga’ cookie.
In addition to reporting website usage statistics, Google Analytics can also be used, together with some of the advertising cookies described above, to help show more relevant ads on Google properties (like Google Search) and across the web.
Sometimes an advertising cookie may be set on the domain of the site you’re visiting. In the case of our DoubleClick product, a cookie named ‘__gads’ may be set on the domain of the site you’re visiting. Unlike cookies that are set on Google’s own domains, this cookie can’t be read by Google when you’re on other sites. It serves purposes such as measuring interactions with the ads on that domain and preventing the same ads from being shown to you too many times.
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’s site. 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. It’s generally set in the googleadservices.com domain (you can find a list of domains we use for advertising cookies at the foot of this page). 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.
