AdSense approval and ongoing policy compliance are two different problems, and most tools only help with one of them. AdSense Support tracks both: it follows your approval status end-to-end, scans your managed sites for policy issues before they turn into a suspension, and builds revenue forecasts so you're not flying blind between payment cycles.
The site scans in particular are meant to catch problems — thin content, ad placement issues, policy violations — before AdSense's own review does, since a rejection or suspension costs you review-queue time you don't get back.
If the approval tracker got a new site through review, or the policy scanner caught something before it became a suspension, that's the kind of story worth sharing here.
