Backfill Evar (fill in for prior instances)


Level 1

An evar persists throughout the session once it's triggered. However, is it possible to go in the opposite direction and populate this for all prior hits once that evar is triggered?

No, not that I've ever seen or read about... 


Now, there's a semi fake way to do this with Segments... 


Let's say you have a user that does this behaviour:

  • Page 1
  • Page 2
  • Click Action A
  • Page 3
  • EventX triggered (either on a Page X or Action X)
  • Page 4
  • Action B
  • etc

If you look for EventX, you will get the Page or Action X, Page 4 and Action B


But, if you create a Visit Level Segment where EventX exists, your Workspace will also include Page 1, Page 2, Action A, Page 3 along with Page or Action X, Page 4 and Action B (since ALL of these were part of the Visit).


You can also do the same with a Visitor Segment, where traffic from previous visits for that user will be returned - assuming you want to see data from earlier and later visits... but if your eVar is set to Visit level expiry, you likely just want to stick with a Visit segment.
