Why Is the Google Ads Conversion Code more Accurate than Google Analytics

Here is why Google Ads counts its own sales better than Google Analytics can count those sales -

 

Google Analytics often mis-credits sales to sources that weren't the ones to drive the customers to the site, such as the store's domain and checkout services, emails and onsite's promotions, and the channel "Direct/none".

 

Store's domain and checkout services should be added to the referral exclusion list - see here how.

Emails, onsite's promotions, and direct/none are the reason that the Google Ads Conversion Code will always be more accurate as it would not lose its credits for those channels.
