The Day(s) since last session criterion is a segmentation criterion that enables you to create a segment.
The Day(s) since last session criterion enables you to create an audience segment based on the date of your visitors’ last visit (or session).
A session ends after 30 minutes of inactivity or when the user closes their browser window.
Let’s say a user visited your website for the last time 20 days ago and hasn't returned. If you’ve created a segment based on the “Days since last session” greater than “22” criterion, the user will join your segment precisely 3 days after its creation, as soon as they return to your website.
The number in the “days” field needs to be reached. If you enter 15, the number of days between the last session and the day of the return visit will have to equal at least 15.
AB Tasty records the date of their last session using the cookie placed on the visitor’s browser. When the visitor returns to the website, AB Tasty checks the amount of time that has passed between this timestamp and the current date and approves visitor inclusion into the segment (or not).
This segmentation criterion is based on the AB Tasty cookie that saves the number of sessions. If the user clears their cookies, uses a new browser, another device, or the incognito mode to visit your website, they will be considered as a new user and AB Tasty will be unable to acknowledge them as part of the segment or to count their new session.
💡 Use case
Basing yourself on the “Days since last session” criterion could enable you to create an audience segment targeting all users who haven't returned for a long time (this notion being specific to each business) in order to push a “Welcome back Message”. Used in combination with the “Number of sessions” criterion, it would enable you to create a segment of formerly very active visitors (recurring high visits) who have not returned at all for a while.
