Adding GTM to Store pages to track purchases

[ShannonPhillis]

Hello

How do I add GTM to track purchases from advertisting sources?

I have added both Header and Body HTML to standard weebly pages but need to track through to payment / checkout / receipt pages to really understand which advertising is generating sales.

Thanks in advance

Tim

Hi Tim. Can you clarify what you mean by GTM? It might also be helpful if you post a link to your site. Thanks so much!

Google tag manager. We cannot track anything on the ecommerce pages.

Thanks for clarifying. I know you can add a GA code to the store by clicking Manage Store>Setup>General. Do you have any instructions from Google that you are referencing?
