  We pulled 20 US Google SERPs across the AI search tools category and classified all 330 organic results. Every query carries an AI Overview. 51.5% of results come from vendors selling a tool in the category they rank for.

3. ## The AI-Blocking Myth: 403 Calgary Sites Later, Almost No One Blocks AI (and the Ones Who Do Picked Wrong)
