We read Google's own guide to AI search. The revolution isn't what you've been sold

If you’ve spent any time on LinkedIn this year, you’ll have seen the funeral notices. SEO is dead. GEO is the future. Rip up your strategy and start again.

So, when Google published its official guidance, “Optimizing your website for generative AI features on Google Search”, I read it properly. Every line. Twenty years in this industry teaches you to check the source before you panic.

Here’s the short version: the fundamentals haven’t gone anywhere. Google says so itself, in black and white.

AI search still runs on the search index

The first thing that jumps out is how dependent Google’s AI features are on the machinery we already know. AI Overviews and AI Mode aren’t some separate system floating above Search. They’re rooted in the same core ranking and quality systems that have decided visibility for years.

The technique underneath it is called retrieval-augmented generation, or RAG. Strip away the jargon and it’s simple. Before the AI writes a word, it goes shopping in Google’s search index for relevant, high-quality, up-to-date pages. It reads what it finds, then generates an answer grounded in those sources – with links back to them.

No index presence, no retrieval. No retrieval, no citation. The AI can’t quote a page it never found.

One question, many searches

The other concept worth understanding is query fan-out.

When someone asks a nuanced question, Google’s models don’t run one search. They fire off a set of related queries behind the scenes to build a fuller answer. Google’s own example: “how to fix a lawn that’s full of weeds” might fan out into searches for herbicides, chemical-free removal and prevention.

Think of it like a scout at a football match. They’re checking the movement off the ball, the shape, the full picture before writing the report – not just watching the striker.

What does that mean for your content? Broad, genuine coverage of your topic matters more than ever. If your site answers the surrounding questions as well as the obvious one, you’ve got more surface area to be retrieved. Not because you gamed anything – because you’re actually useful.

Commodity content is the real casualty

One question, many searches

If anything in the guidance should worry people, it’s this. Google draws a sharp line between commodity content and non-commodity content.

Commodity content is “7 Tips for First-Time Homebuyers” – the stuff anyone could write, and now any AI can write in 8 seconds. Non-commodity content brings a unique point of view, first-hand experience, an expert take that goes beyond common knowledge.

The AI systems look across a variety of sources. If your article says exactly what the other 40 sources say, why would it need you? The sites that get surfaced are the ones contributing something the model can’t get anywhere else.

The irony is lovely. The rise of AI-generated content has made human expertise, experience and originality more valuable in search, not less.

Write for humans. Google keeps saying it.

The quality guidance all points the same way. Organise content so readers can follow it – clear sections, sensible headings, well-written paragraphs. Add images and videos when they genuinely improve understanding, not as decoration.

And Google offers one test for every decision: 

Would your visitors find this satisfying? 

Not “would this trick the model”. The guidance comes back to serving the end user again and again, and warns explicitly that churning out pages for every query variation just to manipulate AI responses violates its scaled content abuse policy.

The technical bar: eligible, not perfect

To appear in AI features, a page needs to be indexed and eligible to show in Google Search with a snippet. That’s it. No additional technical requirements.

The basics still matter – crawlability, indexing, decent page experience – but Google is refreshingly relaxed about perfection. It even says you don’t need flawless semantic HTML, because most of the web isn’t valid HTML anyway and Google copes fine.

What Google says you can ignore

This is my favourite section of the whole document, because Google directly debunks tactics being sold right now as essential GEO services:

• LLMs.txt files – Google Search doesn’t use them. Create one if another platform needs it, but it neither helps nor harms your Google visibility.
• Chunking content into bite-size pieces for AI – not required. Google’s systems understand multiple topics on a page and surface the relevant part.
• Rewriting content specifically for AI systems – unnecessary. The models understand synonyms and meaning. You don’t need to capture every phrasing variation.
• Piling on structured data – it’s not required for AI features and there’s no special schema to add. Keep using it for rich results, but it’s not a golden ticket.

If someone’s invoice depends on you believing otherwise, read Google’s guidance before you sign.

One fair caveat. Content will keep evolving as Google gets better at understanding entities, topics and the relationships between them. But that’s optimisation in the proper sense – helping Google recognise your expertise – not writing prose for robots.

Authority still can’t be faked

On links and mentions, nothing has softened. Google warns against chasing inauthentic mentions across the web, because its quality systems reward what’s credibly said about you and its spam systems block the manufactured stuff. Trust and reputation are earned the slow way. Same as ever.

The honest conclusion

Having read the documentation end to end, the reality feels far less revolutionary than the noise suggests.

GEO isn’t a replacement for SEO. It’s largely good SEO, applied with an understanding of how AI-powered search retrieves, evaluates and presents information. The retrieval layer is new. The fan-out behaviour is new. The fundamentals underneath – useful content, genuine expertise, sound technical foundations, authentic authority – haven’t moved an inch.

The rationale has evolved. The work remains reassuringly familiar.

And if your agency is telling you otherwise? Ask them to show you where Google says so. We’ll wait…
