Types of Cookies
We use different types of cookies to run our website and ads-related products. Some or all of the cookies identified below may be stored in your browser. You can view and manage cookies in your browser (though browsers for mobile devices may not offer this visibility).
Advertising (via Google Adsense / YouTube Ads)
Sometimes an advertising 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. 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 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, and have names like ‘Conversion’ and ‘TAID’. Conversion cookie data may also be used in combination with your Google account to link conversion events across different devices you use. Only anonymous 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.
Websites often collect information about how users interact with a website. This may include the pages users visit most often, and whether users get error messages from certain pages. We use these so-called ‘session state cookies’ to help us improve our services, in order to improve our users’ browsing experience. Blocking or deleting these cookies will not render the website unusable.
These cookies may also be used to anonymously measure the effectiveness of PPC (pay per click) and affiliate advertising.
For example, Google uses a cookie called ‘recently_watched_video_id_list’ so that YouTube can record the videos most recently watched by a particular browser.
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.
