It’s normal for Recirculation Rate + Exit Rate to total more or less than 100%.
Here’s why:
Exit Rate excludes sessions that ended in a conversion
Recirculation Rate includes all sessions, including those that converted
So if a significant portion of visitors converted on the page, the Exit Rate will be lower (since those sessions are excluded), while Recirculation remains unaffected—causing the combined total to exceed 100%.
In short: The two metrics are calculated from different session sets, so they aren’t meant to sum to exactly 100%.
