AI Defender is a traffic-quality plugin that runs a daily AI analysis on historical traffic, identifies low-quality or suspicious sources and adds them to the blacklist automatically. It costs $199 / month (AI Defender).
What it does
- Daily analysis of historical traffic.
- Low-quality sources blacklisted automatically.
- Review every decision and undo it.
- Protects budgets without manual work.
How it differs from pre-bid filters
| Pre-bid filters | AI Defender | |
|---|---|---|
| When | At each request, in milliseconds | Once a day, on past traffic |
| Looks at | Known bad sources, fake domains, invalid signals | Patterns across days of results |
| Catches | Obvious bad traffic | Sources that look fine per request but perform badly over time |
They work together: pre-bid stops what is known, AI Defender learns what wasn't.
Reviewing its decisions
Check its blocks regularly, especially for advertisers with unusual funnels — a source that looks poor for one goal may be fine for another. Every decision can be undone.
