Trying to develop my adwords account to show product picture ads through 'importing' the Google Merchant Center feed into Adwords.
In a quandary as to what works best - Google Product Ads OR Product Extensions.
Has anyone had experience using either or preferably both systems and has data to share regarding success (or lack of) from using them.
Also, is there a best way to set them up. Been searching and searching but not much discussion on this topic.
