2nd October 2020: Video 2 – How to Verify and Confirm Your GTM Container is Working…

Below is a summary for all of the things that needs to be done based from all of the videos above. You can also use this to troubleshoot any GTM issues.

1. Import Leadshook Container
2. Update Variables (Google Analytics Tracking which is the UA-ID, FaceBook Pixel ID etc. .)
3. Update Variable = Your domain (Include www if domain resolves with www. Do not add https://)
4. Update Variable = Subdomain (Use LeadsHook subdomain “yoursubdomain.leadshook.io”. Do not add https://)
5. Update Triggers = All Pages Parent Domain ( Needs to be the same as your Domain variable)
6. Update Referal Excusion via Google Analytics setting (LeadsHook Subdomain, Website Domain w/ www and also Website domain w/o www) Don’t add https://.
7. Paste GTM codes above head and above body within LeadsHook and External site.

Common Mistakes

Mistake #1: Not Updating “All Pages Parent Domain” Trigger

While in most cases you can add variables, when using Page Hostname, variables don’t seem to work. So please manually update your domain as shown below…

Mistake #2: Universal Analytics Tag does not contain cookieFlags custom field

Please ensure you are using the latest GTM container. The most current container should have this additional custom field in the “Universal Analytics” tag

cookieFlags  samesite=none;secure

Mistake #3: GTM top Origins Variable should be the same as your Domain Variable

Please make sure you supply information on your GTM top Origins and GTM origins Variable.

By default it should be using your Domain Value, but it would be better to manually change it, and take note there are two values

“http://{{Your Domain}},https://{{Your Domain}}”

It’s an http version beside https separated with a comma.
