The rep is confused. There is ALMOST no correlation between AAR and Ad Rank… EXCEPT that the changes made through recommendations, auto applied or manual, is that they don’t affect the algo the same as if you applied them directly since an algo made the recommendation.
Example –
* *Remove redundant keywords*
Since **Ad Rank** includes the history between your keywords and ads, if you remove what you consider a redundant keyword, the algo’s learning will be somewhat disrupted. The example above is also great backdoor way to help simplify an account.
If you are using, or intend on using, Maximize Conversions using a target CPA on all campaigns, these are fine:
* *Bid more efficiently with Maximize conversions using a target CPA*
* *Set a target CPA*
Unless you have a sizeable budget, do NOT use –
* *Adjust your CPA targets*
Note – Google has said they want to move all accounts to ROAS bidding over time, which is probably why he suggested it. But that’s a separate discussion. If you don’t have both high volumes of conversions or conversion values set for each conversion action and reporting back for the last 30 days, ROAS bidding would be tank your performance.
