A pre-flight editorial check on twelve client RSAs found that 43 of 60 submitted headlines had at least one red flag. Here is the five-bucket taxonomy of what Google's review actually catches, and why your Ad Strength is stuck at Average.
Export your RSA asset report, ask Gemini to grade every pin on 4 dimensions Google doesn't even measure, flag the bottom 30, then rewrite them with a structured prompt. The full audit takes 2.5 hours, saves about 6 versus doing it by hand, and the rewritten assets routinely lift impression volume and ad strength within 30 days.
