The default filters suit most traffic, but not every business. A large advertiser may want stricter rules; a partner you know well may need an exception. The Ad Fraud Protection page confirms rules can be customized per advertiser, campaign or traffic source, with whitelists for trusted partners.
Stricter rules
Use stricter rules for:
- Brand advertisers who can't appear on doubtful placements.
- Campaigns paying for conversions, where click fraud costs the most.
- Sources with a history of low click quality.
Combine with placement blacklists, the Click Quality Score and, for daily automatic blocking, AI Defender ($199 a month).
Whitelists
A whitelist tells the platform a partner or placement is trusted. Use it carefully:
- Only for partners you know well, with a track record of clean traffic.
- Document why each entry is there.
- Review regularly. A good source can change.
Whitelists don't switch off the pre-bid filters for bots and fake domains; those protect everyone.
Account-level whitelists of sites and apps
For targeting rather than fraud, the Whitelists plugin ($290 one time) lets advertisers keep lists of sites and apps and apply them to any campaign.
