Recommendations & optimization score
Recommendations is an entire section of your Google Ads account dedicated to helping you improve your campaigns. Recommendations can introduce you to new features, and help you get more out of your budget by improving your bidding, keywords, and ads.
Within the Recommendations Page, you will find your optimization score, an estimate of how well your Google Ads account is set up to perform. Applying or dismissing recommendations changes the overall optimization score of your account.
