About two weeks ago, the bounce rate for pages on my sight dropped drastically. We went from an average of 70%-80% bounce a page to 2%-20%. It's an absolutely drastic change overnight. While I'd love to take credit for it, this seems wrong. A few things are tipping me off:
- Despite the bounce rate being so low and pages/session being so high, duration per session is tanking. Getting things like 3.75 pages/session with a duration of fewer than 10 seconds.
- Pageviews are often near double the Unique Pageviews count
My fear is that for some reason the page tracking is triggering twice per page. Is this possible? And is there a better way to confirm it. I tried running an experiment with Google Optimize and Google Tag Manager and that coincides with when this data change happened. I've disabled both but the data remained the same.
Any insight would be greatly appreciated.
