Now I saw this mistake at an account a few weeks ago.
They were measuring contains thank-you as a conversion.
The problem…
The company had multiple thank-you pages for example:
thank-you-job-applicant and thank-you-malfunction.
Now we only wanted to measure thank-you-quote-request.
So I made some changes of course.
This is also one of the reasons why I rather want to measure events instead of pages.
