In the Transitions report, we display a metric called Exits. This metric is calculated in an approximate way and this issue aims to explain this known limitation.

This metrics for a given page, is processed via the formula:

• Exits = PageViews - (FollowingActionsViews + Loops)
  • FollowingActionsViews is the count of actions done by user on this page (eg. pageviews, site searches).

Imagine a user on a given page will do several follow up actions (eg. open several pages without somehow reloading the page) then the count of FollowingActionsViews could be greater than PageViews and Exit could be negative.

Unfortunately there is no easy fix for now as it would involve changing the API to only keep one action per visitor or something similar (I don't know if it's possible without big performance overhead).
