I probably should have noticed this a long time but I don’t usually think of how many times a specific page (URL) has been visited, so I was shocked at how much larger that the page view number is compared to unique page views. 6x-10X more? Not possible.
The best way to figure out why there is such a big difference is to find example sessions with multiple page views of that type and check whether they are happening naturally, or if it is the same page view repeating in a short period of time. You can do this by adding a visitor ID as an additional column and ordering the data by the number of page views. This way, you’ll identify the visitor with the highest number of page views, and then, using that visitor ID, you can go to the session log, search for the visitor, and review how the session looks.
If it is not a natural behaviour then visit the page via tag manager debug mode, follow the user steps and check what’s happening on the front-end. The tag manager with combination of network tab (where you look for ppms.php requests) might give you an answer if the behaviour is not natural.
I looked at visitor ID and can see that several visitor IDs counted for one unique view of a page but 50 or more page views. That’s not natural behavior. I checked the session for one of the offending visitor IDs and see this information:
Council Bluffs, United States
Provider name: Google LLC
Organization: Google LLC
This feels like bot. So I added “city” as column in the pages reports and, sure enough, all of the traffic is from one city in Iowa:
