Do you know how long it takes for the Google Analytics cookie to time out before a user is recognized as new again? I believe it is 2 years. Is that right?
Depending on what cookie you mean exactly, 2 years would probably be the answer you're looking for based on this source: https://developers.google.com/analytics/devguides/collection/analyticsjs/cookie-usage
Google itself lists three main cookies that are set by the analytics script:
- "_ga" with a lifetime of "2 years" that is "Used to distinguish users."
- "_gid" with a lifetime of "24 hours" that is "Used to distinguish users."
- "_ga" with a lifetime of "1 minute" that is "Used to throttle request rate."
Beyond that there are 7 more specific cookies that handle things like distinguishing between users/sessions and setting user level data. Their expiration time is between 10 minutes and 2 years.
