Short answer
Hover over the "Not serving" status in Ads Manager to see the reason. The usual causes are a policy rejection, a landing page that blocks OpenAI's crawlers, unfinished verification or account review, a billing problem, a spent budget, dates that don't include today, or a paused campaign or ad group.
Causes and fixes
| Cause | Fix |
|---|---|
| Ad or landing page conflicts with policy | Edit and resubmit, or request review |
| Landing page blocks OAI-AdsBot or OpenAI IPs | Allow the crawler in robots.txt, CDN and firewall |
| Verification or account review pending | Complete verification; wait for review |
| Failed payment | Update the card |
| Budget spent or weekly allowance used | Raise budget or wait for the new budget week |
| End date passed or start date in future | Edit dates |
