Flags ad assets (headlines, descriptions, images) that Google has rated "Low" and that have served enough to be fairly judged, grouped by campaign. The "served enough" floor is the important part - it stops the rule firing on brand-new assets that simply haven't had a chance yet.
Defaults & settings
Minimum impressions - only flag assets with enough data to judge; avoids noise on brand-new assets. Default 500, adjustable 100-10,000.
Exclude pinned assets - skip pinned RSA assets; they're intentionally locked in place, so a performance judgement doesn't apply. On by default.
Checks weekly; 7-day cooldown.
Example. Two headlines rated Low with 2,000+ impressions each are dragging an RSA's combinations. The weekly flag lists them by campaign - a ten-minute rewrite in the next optimisation session.
