Google Gives Publishers an AI Opt-Out Switch — But Only in the UK for Now

Website owners just got their first official tool to opt out of having content appear inside Google's AI features. A new toggle in Search Console lets publishers block their pages from showing up in AI Overviews, AI Mode, and AI-powered Discover results — but right now, it's only available to a small group of UK site owners, and the rollout is legally required.

The UK's Competition and Markets Authority (CMA) mandated that Google give publishers control over how their content is used in AI features, including the ability to opt out of fine-tuning AI models.

Key Takeaways

• The opt-out toggle is separate from the new AI performance reports — it's a control layer, not just a reporting layer
• Google confirmed: blocking content from AI features does not affect regular search rankings
• The control currently applies only to .co.uk domains; broader rollout is required within nine months under UK regulation
• AI performance reports include impressions data starting May 18, 2026 — but no click data
• Early polling of SEOs found about 33% would use the opt-out feature

For content strategists and marketers, this signals a fundamental shift: AI search and organic search are becoming two separate channels, each requiring its own strategy and measurement framework. Publishers now have the choice — show up in AI results and gain impressions without guaranteed clicks, or opt out entirely.

Neither choice is obviously right, but having the choice at all is new. Watch for this control to expand globally as other regulators follow the CMA's lead.
