On June 5, 2026, Google added a Search Central documentation page on third-party SEO tools, services and advice, and expanded its "Do you need an SEO?" page. Three questions now form the official grid for judging a provider, one of which is directly about AEO/GEO. Google also restates that it does not evaluate or endorse any third-party SEO tool, and encourages reporting deceptive practices.
On June 5, 2026, Google updated its official Search Central documentation to help businesses evaluate an SEO provider and the tools it uses, according to the Google Search documentation changelog. Two changes: a new page on third-party SEO tools, services and advice, and an addition to the "Do you need an SEO?" page on how to evaluate your provider's recommendations and tools.
Direct answer: Google does not rank agencies, but it now gives a public grid to judge them. The three key signals: (1) does the provider cite official Google documentation to back its advice? (2) is its AEO/GEO advice aligned with Google's official guidance for generative AI? (3) does it use tools consistent with that guidance? Everything else, ranking guarantees, opaque cold outreach, link schemes, remains a red flag.
What Google actually added
The most strategic addition concerns third-party SEO tools. Google writes plainly that it "does not evaluate or endorse third-party SEO tools" and that these tools "don't have access to Google's internal ranking data." In other words: a difficulty score, an "SEO score" or a volume estimate shown by a tool is a model, not an official Google number. Yet some users mistake them for Google data, Google is ending that ambiguity.
The operational advice is clear: before any significant change based on a third-party tool's audit, check its recommendations against official documentation, think critically about claims, and make your own informed decisions. That is exactly the mindset of reading a tool's report with perspective rather than as absolute truth, a reflex we detailed around the AI performance reports in Search Console.
The official grid to judge an agency
Google adds three questions to ask a provider, on top of the classics (examples of past work, adherence to the Google Search Essentials, transparency on changes). Here is how to read them.
| Google's question | What a good answer looks like |
|---|---|
| Does the provider cite official Google documentation to support its recommendations? | Every recommendation points to a Google source (Search Essentials, official guides), not to an unverifiable "hack." |
| Is its AI optimization advice (AEO/GEO) aligned with Google's official guidance for generative AI? | No magic promises about llms.txt, "chunking" or special schema: Google confirmed none of that is required for its AI features. |
| Does it use tools consistent with Google's guidance? | Tools are used to measure and prioritize, never to justify manipulations banned by Google's rules. |
A detail that matters for our industry: Google added "optimizing for generative AI" to its list of legitimate SEO services. GEO is no longer a marketing gimmick, it is a recognized service, provided the advice stays aligned with Google's position, for which optimizing for AI search is "still SEO."

What it changes for small businesses
In practice, this update rebalances the relationship between a business and its agency. Until now, many owners had no reference point to challenge a recommendation. Now, the question "can you show me the Google doc that justifies this?" is legitimized by Google itself. A serious agency answers in thirty seconds; an agency selling hot air runs out of arguments.
This clarification lands in a busy context: the May 2026 core update just finished after a volatile rollout, and visibility increasingly plays out in AI-generated answers, a field where Google and Microsoft push formats like passages cited by AI agents. In that fog, an official reference for judging who advises you is no small thing.
The signal flying under the radar: the FTC
Google goes beyond education. Its documentation now encourages reporting deceptive providers: in the US, it explicitly points to the FTC (1-877-FTC-HELP), according to the analysis by Search Engine Journal. The message is unambiguous: SEO is not a lawless zone, and Google wants to clean up a market still full of unrealistic promises.
What this guide does not say
Let's be honest about the limits. This document ranks no agency and creates no "Google-approved" label, be wary of anyone who claims otherwise. It also does not guarantee that a provider ticking all three boxes will get results: citing the official docs is necessary, not sufficient. Finally, it stays focused on Google Search: it covers neither the specific citation mechanics of ChatGPT, Perplexity or Claude, nor the business trade-offs (budget, priorities, timelines) that decide whether a strategy converts.
Our take
This update validates what we've said from day one at Cicero: an SEO recommendation without an official source is just an opinion. We build every audit and every piece of content on Google's documentation, and our GEO approach follows the same alignment rule. The real news isn't that Google hands out a grid, it's that it just turned "show me your sources" into a standard question. Good.

FAQ
No. In its documentation updated on June 5, 2026, Google states it does not evaluate or endorse third-party SEO tools, and that these tools do not have access to Google's internal ranking data. The scores and metrics these tools display are estimates, not official Google data.
Google recommends asking: does the agency cite official documentation to support its recommendations? Is its AEO/GEO advice aligned with Google's official guidance for generative AI? Does it use tools consistent with those recommendations? Google also suggests asking for examples of past work, adherence to the Google Search Essentials, and transparent reporting of changes.
Partly. Google added "optimizing for generative AI" to its list of legitimate SEO services. But its position remains that optimizing for AI search is optimizing for the search experience, and is therefore "still SEO." The key is that AEO/GEO advice stays aligned with the official guidance.
Google now encourages reporting deceptive practices. In the US, its documentation points to the FTC (1-877-FTC-HELP). The best preventive habit is to require a clear contract, a detailed record of the actions taken, and access to reports.
