PageView Events and Deduplication Issue (Why is Event Coverage so Low)

Hi all,

I am using sGTM with CAPI along with the Event ID Template by Stape. I have several events that seem to be doing fine with event coverage and deduplication with this setup with over 90% event coverage, but for some reason PageView events get stuck at 35% or lower, even though it’s set up the same way. I went and tested to make sure deduplication was working by visiting a random page:

So it seems like it’s working correctly, but while I was testing, it was recording other pageview events by a visitor visiting a specific page over 3-5 times within seconds, each with its own event ID, and none were deduplicated. This feels like a bot visiting and spamming the page with views, so I’m wondering if maybe this is why? My other events lead to low traffic pages so they don’t seem to experience this issue.

Any insights appreciated!

This is what occurred while I was testing with some visitor/bot repeatedly visiting a page

Finally this is what my events coverage looks like:

In test events, you only see events that you generate; you cannot see events from third-party users or bots there.

This means that you are generating unnecessary events. Most likely, they are triggered more often than you think. I recommend running a preview of your web and server container and checking whether all tags are working as expected.

I can confirm this wasnt the case, while I was testing events pageviews appeared for a web page that I was not visiting at all. I think this is due to testing server events not browser events, where I had to use a Test code for the Meta tag in my server container, so that would have picked up any traffic visiting our website.
