Google Publisher Center 2.0 and AI opt-out: what it really changes for your SEO

Google rewrites the rules — again

One of our clients called us last week, slightly panicked. He had read something about “Google letting sites opt out of AI”. His question: “Should I block Google AI on my site?”

Short answer: it depends. And the real answer is more nuanced than what you’re reading right now on most SEO blogs.

Two recent announcements from Google deserve serious attention. On one side, a major evolution of Publisher Center with enriched publisher profiles — which looks very much like a Publisher Center 2.0. On the other, Google finally offering websites the ability to opt out of AI Search. With a significant catch: without giving them the data needed to make an informed decision.

Let’s break it down together.

What Google calls “extended profiles” — and why it matters

Publisher Center has existed for years. Few SME website owners have ever heard of it. It’s the tool that allows content publishers to declare their identity to Google: who publishes, in what sector, with what editorial line.

Until now, it was mainly useful for large media outlets. Le Figaro, Le Monde, high-volume news sites. For a local craftsman or a small business, the value seemed limited.

What changes with extended profiles is the granularity of information Google now agrees to take into account. We’re talking about finer authority signals: precise industry, declared expertise, editorial history, source credibility. In short, Google is trying to better understand who speaks before deciding how to display the content.

What agencies never tell you: this evolution is directly linked to the rise of AI in search results. Google needs structured data on publishers to feed its models and decide which sources deserve to appear in AI-generated responses. We already detailed this mechanism in our analysis of Google AI Mode and preferred sources that really change your online visibility.

Concretely, for an SME or professional who regularly publishes content on their site, ignoring this evolution means leaving Google to guess who you are. And Google guessing is rarely in your favour.

The AI opt-out: a real step forward, but a poisoned gift

Here’s where it gets interesting.

Google announces that website owners can now request not to be used in AI Search responses — particularly in AI Overviews (the automatically generated summaries that appear at the top of results).

On paper, this is a significant concession. After months of pressure from publishers, agencies, and press associations, Google implicitly acknowledges that taking content from a site to feed an AI response without compensation or consent is problematic.

But here’s the trap.

To make an informed decision about whether to activate this opt-out, you need to answer a simple question: what share of your organic traffic currently comes from AI Overviews? Is Google citing you in its AI responses? Does it bring you visitors, or is it cannibalising your clicks?

Google doesn’t give you that data.

Google Search Console doesn’t distinguish clicks from classic results from those coming from AI Overviews. You’re navigating blind. You can activate the opt-out, but you won’t know what you’re losing — or what you’re gaining.

“Giving publishers the ability to opt out without the data to make an informed decision is like offering someone a contract with the key clauses redacted.” — Matt Southern, Search Engine Journal

That’s exactly it. You’re given a button without being told what it really triggers.

Should I activate the AI opt-out for my site? The real question

Let’s flip the situation. Instead of asking “how to activate the opt-out”, first ask yourself: what is your current traffic model?

If your site lives primarily on informational searches — blog posts, guides, advice sheets — you’re potentially in the crosshairs of AI Overviews. Google tends to synthesise this type of content directly in its responses. Result: your content is used, but the user no longer needs to click on your site.

If your site is transaction-oriented — product pages, local service pages, quote requests — the risk is different. AI Overviews are less prevalent on high purchase-intent queries. Blocking AI could deprive you of visibility with no real benefit.

In our day-to-day agency work, we support many local SMEs whose traffic is mainly local and transactional. For them, the AI opt-out is rarely a priority. What matters is being well-positioned on queries like “plumber Caen”, “bakery Bayeux”, “accountant Rouen” — and there, AI Overviews are still not very present.

On the other hand, for a consulting firm, a professional blog, or a site that produces educational content to attract prospects, the question deserves serious analysis.

What this concretely means for your content strategy

After 15 years supporting SMEs with their web presence, I see in these two announcements a clear signal: Google is structuring its ecosystem around the credibility of sources.

This isn’t fundamentally new — E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) has been in Google’s guidelines for years. But extended publisher profiles and the AI opt-out logic are accelerating this trend. For the details of the new rules, the official Google AI guide really says this about SEO 2026.

What we concretely see with our clients is that the sites performing best in this environment share several things in common:

They sign their content. Not just a first name at the bottom of an article — a real author page with declared expertise, links to verifiable professional profiles, consistency between the LinkedIn profile and the site bio.

They publish consistently. Not one article a month on a random subject, but a clear editorial line in their sector. Google understands a site that always talks about plumbing in Normandy better than one that alternates between cooking recipes and legal advice.

They structure their data. Schema.org, structured data, semantic markup — everything that allows Google to understand without ambiguity who publishes, on what, and why. It’s technical, but it’s precisely this type of signal that Publisher Center’s extended profiles will reward.

The three actions to take now

Our experience confirms it: in the coming months, the sites that have worked on their publisher authority signal will be better positioned — whether in classic results or in AI responses.

Here’s what I would do if I were in your position, with a limited budget and limited time:

First action: check your presence in Google Publisher Center. If you regularly publish content, create or update your profile. State your industry with precision. It’s free, takes two hours, and sends a direct signal to Google about your editorial identity.

Second action: audit your author pages. Every article published on your site must be signed by a real person with verifiable expertise. If you have anonymous articles or ones signed “The GDM-Pixel Team”, that needs fixing. Create complete author pages with biography, area of expertise, and links to external profiles.

Third action: don’t make a decision on the AI opt-out before you have data. Monitor your organic traffic in Search Console at maximum detail. Note your current positions. In six months, you’ll have a baseline to evaluate the real impact of AI Overviews on your site — and decide with full knowledge.

The question nobody is asking yet

Here is the core of the problem, and this is what agencies never tell you: Google is building a two-speed system.

On one side, publishers who play the game of extended profiles, who structure their content for AI, who accept being referenced sources in generated responses. They will gain visibility in Google’s AI ecosystem, perhaps at the expense of direct traffic to their site.

On the other side, publishers who opt for refusal, who protect their content. They retain control, but risk being progressively marginalised in a search engine that bets increasingly on generated responses.

The problem is that Google doesn’t give you the tools to choose intelligently. No data on the contribution of AI Overviews to your traffic. No visibility on how your content is used in AI responses. You choose blind.

“Opting out without data is like asking someone to sign a contract with the key clauses redacted.” — paraphrase of Matt Southern, Search Engine Journal

This is the fundamental imbalance in the relationship between Google and publishers in 2025. And neither Publisher Center 2.0 nor the AI opt-out truly resolve it.

What we do at GDM-Pixel in the face of these developments

Concretely, we’ve made three decisions for our own sites and those we support:

We systematically structure author data on all projects we deliver. Schema.org Person, complete author page, profile consistency. This is no longer optional in our delivery workflow.

We help our clients update their Publisher Center when they publish content regularly. Two hours of work that sends a strong signal to Google about the credibility of the source.

We don’t recommend the AI opt-out by default. We wait until we have sufficient data to advise case by case. On a local e-commerce site, it’s probably unnecessary. On an informational content site with high organic volume, it deserves consideration.

Effectiveness before buzz. ROI before knee-jerk reactions. It’s the same logic we apply to all the SEO services we carry out at GDM-Pixel.
