Are cookies still effective?
Re: Are cookies still effective?
- Distinguish unique users
- Throttle the request rate
analytics.js sets the following cookies:
- Cookie Name: _ga - expiration time 2 years, used to distinguish users.
- Cookie Name: _gat - expiration time 10 minutes, used to throttle request rate.
If you're using Google Analytics' Display Advertiser features, such as remarketing, a third-party DoubleClick cookie is used in addition.Third-party cookies are associated with a domain that is separate from the site a user visits.
All the websites that you use on a daily basis or on a weekly basis, will see you as a new user after you've deleted your cookies.
One more thing that would be interesting to know. First party cookies are not shared across devices so if you visit a specific site with your mobile and 3 hours later with your laptop, GA will not understand that you were the same person unless you didn't log in (if UserID tracking is implemented, it's possible to make sure, you were the same person).
Hope this help. Let us know if you have any further questions.
