NEED: We need to analyze which website is achieving more sales from customers that buy after clicking the buy button.
QUESTION: Is there a way to monitor it? Is it possible to change the code of the embbed buy button to inform the Google Analytics pixel of the website where is embbed?
I’m not sure that I can give you the right solution for your context but I think it can help somehow.
So basically, if you are managing many different websites to sell your product, so on GA properties, each website will be (and should be) a separate properties. And on all of your GA of websites, you can set the clicking buy button action as Goal Conversion Rate and Goal Completions (Event action). You can name that event whatever you want (Click Buy Button, Click Buy course,…) and you name it the same in all of your website. So it will help you to be able to track on GA that which website are having more Goal Completions event.
