I have a dental website for getting appointments. The CTA 'Book an appointment' opens a partner website and the user can see my locations and book an appointment.
Now, to measure Google ads performance, I need to track users coming from Google ads and differentiate them from organic traffic. I have set up the google tag manager, along with the Google Ads conversion tag, and set the trigger on 'Click class'. It's showing the organic traffic in analytics but not coming from ads. I have placed the link with all the UTM parameters in Google ads.
What is wrong here or what is the best possible way to track the clicks on the 'Book appointment' button coming from Google Ads?
