For the past year, digital marketers have been operating in the dark. We knew AI Overviews were eating our organic traffic, but Google Search Console (GSC) blended those AI impressions with standard "10 blue link" impressions, making it impossible to diagnose exactly what was happening.
As of June 3, 2026, the blackout is over.
Google has officially begun rolling out the Search Generative AI performance report in Search Console. For the first time, site owners can isolate exactly how their content is performing inside Google's AI Overviews and AI Mode. But reading this new report requires a fundamental shift in how you think about SEO metrics.
What Does the New Generative AI Report Actually Show?
If you are part of the initial rollout (Google is testing this with a subset of domain properties first), you will see a new dedicated AI tab in your GSC Performance section. Here is what it isolates:
- Generative Impressions: How many times a link to your site was shown to a user inside an AI Overview or AI Mode response.
- Pages: The specific final URLs that the AI decided to cite as a source.
- Dimensions: You can break this data down by Country, Date, and Device (Desktop vs. Mobile is crucial here, as AI triggers far more aggressively on mobile).
The Catch: Impressions vs. Clicks
The most shocking element of the new report isn't what is included—it is what is missing. The standard click-through rate (CTR) is not the focus here.
Unlike the standard Search results report, this view isolates generative AI surfaces. In the AI era, an "impression" should be read as brand exposure rather than traffic intent. If your Generative AI impressions are skyrocketing but your site sessions remain flat, the report is telling you that Google is heavily surfacing your content as the answer—meaning the user doesn't need to click.
You must stop treating an AI impression as a failed click. Treat it as a successful digital billboard. If you are securing the AI impression, you are blocking your competitor from securing it.
The New "Opt-Out" Toggle: Should You Block AI?
Alongside the reporting data, Google quietly rolled out a massive new feature: The AI Blocking Control.
Taking full effect in mid-June 2026, site owners now have a toggle to explicitly block their content from being used in AI Overviews and AI Mode for grounding purposes. Google has explicitly stated that "sites that opt out will not receive traffic or impressions from our generative AI features," but clarified that it will not hurt standard organic rankings.
Should you use it?
For 95% of businesses, absolutely not. Blocking Google's AI from reading your site effectively erases your brand from the future of search. The only entities that should consider the opt-out toggle are massive news publishers and data brokers who are actively negotiating licensing deals.
The Blind Spot: Why GSC Is Not Enough in 2026
The new GSC Generative AI report is a massive step forward, but it has one fatal flaw: It only reports on Google.
Google no longer holds a monopoly on answering questions. Millions of users are bypassing Google entirely and asking Perplexity, ChatGPT Search, and Claude for product recommendations, B2B software comparisons, and local services.
Google Search Console will never tell you if ChatGPT is recommending your competitor. It will never tell you if Perplexity has blacklisted your domain due to bad formatting.
To get a true picture of your Generative Engine Optimization (GEO) performance, you must pair your GSC data with a comprehensive AEO and GEO audit. By running your site through AeoAudit, you can measure your Share of Model (SoM) across the entire LLM ecosystem—giving you the complete picture of your brand's AI visibility that Google refuses to show you.
The data is finally here. Make sure you are looking at all of it.
