How often do your ads get rejected because of policy issues?

Hi everyone,

I am building ScanMyAd, a tool that reviews ad copy before campaigns go live and highlights potential policy risks across platforms like Google Ads and Meta.

While running digital campaigns, I noticed many ads get rejected for small wording issues that are hard to catch beforehand.

I’m curious:

• How often do your ads get rejected or flagged?
• What platforms cause the most problems?
• Do you check ad compliance before launching campaigns?

Would love to hear how marketers here deal with this problem.
