Cookie Durations and Purposes: Unpacking the Complexities of Modern Web Tracking

  • Cookies are small text files stored on a user's device by websites they visit, serving as identifiers for tracking behavior.
  • Cookie durations range from a few minutes to several years, depending on the type and purpose of the cookie.
  • The test_cookie has a duration of 15 minutes, while PHPSESSID and JSESSIONID cookies have shorter durations of mere seconds.
  • The __gads cookie has an impressive duration of 1 year and 24 days, tracking user behavior and campaign success.
  • Google Analytics cookies, such as _ga, have durations measured in years, providing insights for website owners and advertisers.
  • Cookies from companies like AddThis, Issuu, and Vimeo also track user behavior and preferences for targeted advertising.
  • A significant number of uncategorized cookies are being analyzed to understand modern web tracking practices.



  • In a world where online tracking has become increasingly ubiquitous, it is essential to understand the intricacies behind the cookies that power this tracking mechanism. The recent revelation of cookie durations and purposes sheds light on the intricate dance between website owners, advertisers, and users.

    At its core, cookies are small text files stored on a user's device by websites they visit. These cookies serve as identifiers, allowing websites to track user behavior, recognize repeat visitors, and deliver targeted advertisements. The context data reveals an astonishing array of cookie durations, ranging from a few minutes to several years.

    One cookie that stands out is the test_cookie, set by doubleclick.net with a duration of 15 minutes. This cookie serves as a diagnostic tool to determine if a user's browser supports cookies, ensuring that targeted advertisements are delivered effectively.

    In contrast, other cookies like the PHPSESSID and JSESSIONID have durations measured in mere seconds, highlighting their transient nature. These session-based cookies store unique identifiers for each user session, allowing websites to track visitor behavior across multiple pages or sessions.

    However, not all cookies are created equal. The __gads cookie, set by Google, boasts an impressive duration of 1 year and 24 days. This cookie tracks the number of times users see an advert, measures campaign success, and calculates revenue – a testament to the advertising industry's reliance on these cookies.

    Google Analytics also plays a significant role in cookie tracking, with cookies like _ga having durations measured in years. These cookies calculate visitor data, session counts, and campaign reports, providing valuable insights for website owners and advertisers.

    Other cookies, such as the YSC and yt-remote-device-id, serve specific purposes related to YouTube's video-tracking capabilities. The yt.innertube::nextId and yt.innertube::requests cookies register unique IDs to store data on which videos users have seen – a critical aspect of personalized advertising.

    Beyond Google and Adobe, other companies like AddThis, Issuu, and Vimeo also rely on cookies for tracking purposes. These cookies often serve as trackers, monitoring user behavior, preferences, or device information to deliver targeted advertisements or enhance the user experience.

    The context data also reveals an assortment of uncategorized cookies – those that have not been classified into a specific category. These cookies are being analyzed and may hold secrets to understanding modern web tracking practices.

    As users become increasingly aware of online tracking, it is crucial to understand the complexities behind cookie durations and purposes. By examining these details, we can better navigate the intricacies of modern web tracking and make informed decisions about our digital lives.
