I have a Google Analytics goal (event) and it is set to fire when people reach a certain page with specific values/parameters included in the page URL. I have set it up in GTM.
You can see the tag on the left and the trigger on the right:
Now the results after a couple of days shows that some goals URL from the sales have been counted twice:
This could happen when somebody clicks on the link it has received by email a second time.
My question is: is there a way to avoid in Google Analytics (or GTM) for a specific URL to be recorded as a conversion twice (or more). Need only to be counted once.
For example, a specific goal URL could look like this:
And I don't want GA to count it twice, never.
