Hi everyone!
So I was poking into my HTTP request and noticed my non-purchase conversions (view_item and add_to_cart) that I am sending to Google ads contain this bttype=purchase parameter
Best I can ascertain is that it is a baked in feature of Google conversion tracking.
And it might be a left over legacy code feature of conversion tracking.
Hopefully that made sense, or is this like total overkill and I’m just going crazy?
