Hi everyone :) So I have a basic question! We have a Google ads account where we are running YouTube cold ads campaign and YouTube retargeting ads campaign in the same account. How can we verify that a purchase came from retargeting ads and not from cold ads campaign? Like some one might have opted in via cold ads but didn't got converted but then they saw retargeting ad and then got converted. In this case, is it possible to have two ad accounts within one Google ad account, one for cold and one for retargeting campaign like we have different and multiple ad accounts inside a BM for Facebook ads? Or we need to have two different Google ad accounts with two different email ID? Thanks!
