Emails you when Google disapproves an ad, sitelink or other asset - which silently stops it from showing. This also catches "destination not working", which is how a broken landing page (a dead link, a 404) shows up in Google Ads, so a hosting problem on the client's site surfaces here too.
Disapproved - the core trigger; always on (locked).
Restricted (limited) approvals - also flag ads allowed to run but with limited reach. On by default.
Destination not working - surface dead landing pages. Available as its own switch.
Policy-topic allowlist - choose specific policy reasons to ignore if they're expected for your accounts (e.g. a topic that always flags in your vertical but is fine). Empty by default.
Checks every 15 minutes; 7-day cooldown per finding so a known disapproval doesn't nag.
How to allowlist a policy topic:
Open the rule's Adjust panel.
Click Edit policy-topic allowlist.
Tick the topics to skip, and save.
