AI overview optimisation is not a separate discipline. Google confirms it is still SEO. What has shifted is how your content gets selected, summarised, and surfaced on the search results page. This post explains what that means for your business.

What are Google’s AI Overviews?

Google AI Overviews are AI-generated summaries that appear at the top of the search results page, above the traditional blue links. They are Google’s evolution of the search generative experience, pulling from multiple web pages and delivering direct answers without the user clicking anywhere.

How do AI Overviews work?

Google uses retrieval-augmented generation (RAG): its AI runs a standard search, finds relevant pages, reads across them, and writes a summary. Source links appear below.

One stat worth knowing: 93.8% of AI Overview citations do not come from the top 10 organic results. Content quality and authority matter more than your ranking position alone.

Google also runs “query fan-out” behind the scenes, generating several related sub-queries to build a fuller answer. Your content can be picked up by any of those, not just the original search query.

Yes. Google confirms this in its official AI optimisation guidance. Its AI features run on top of its core search ranking systems. Rank well organically and you are already in consideration for AI Overviews.

The same technical SEO basics apply. Pages need to be crawlable, indexed, and eligible to appear with a snippet in Google search results. Without that, AI-powered search cannot reach your content at all. What has shifted is the type of content that gets cited.

What actually works for AI overview optimisation?

Is original content really the most important factor?

Yes. Google separates commodity content from non-commodity content. Commodity content covers familiar ground: “10 tips for small business marketing” built on common knowledge. Non-commodity content brings something new, a specific case study, a professional opinion, a detailed breakdown that goes further than anything else on the search topic.

If your content could have been written by anyone with a search engine and a free afternoon, it will not perform in AI search.

First-hand expertise

Write from actual experience and share what you see in practice; the mistakes your clients make, the things general advice misses. That is the material AI-generated summaries are built to surface.

Clear page structure

Organise pages with proper headings and short paragraphs. A page that is easy for a person to navigate is easier for AI systems to interpret. This directly affects your AI Overview performance.

Long-tail depth

AI Overviews run sub-queries behind the scenes. Detailed content covering a topic properly has more opportunities to appear in AI search results. The depth is the long-tail, not keyword density.

Does structured data help with AI Overviews?

Schema markup is not required. There is no special markup that guarantees inclusion. That said, it supports your broader SEO strategy and keeps you eligible for featured snippets and rich results, which still drive valuable traffic.

What does not work?

Do I need an LLMS.txt file?

No. Google confirms LLMS.txt files and other AI-specific markup make no difference to AI Overview visibility.

Should I chunk content into short pieces for AI?

No. Google’s AI systems can understand multiple topics on a single page. Fragmenting content is unnecessary and hurts readability.

Is AEO or GEO something I should be paying for?

Google describes AI overview optimisation as SEO. The terms AEO and GEO are used widely, but Google’s guidance treats them as synonyms for existing practice. Be cautious of agencies selling you packages that “guarantee” results in AI overview. If you want to understand what LLM optimisation genuinely involves beyond Google Search, that is a more specific conversation.

What does the zero-click trend mean for your business?

59% of Google searches now end with no click. AI Overviews are accelerating that for informational queries.

Two things follow. Appearing in AI-generated summaries puts your brand in front of searchers at the point of highest intent, even without a click. And the queries where clicks still happen are increasingly transactional: book, buy, contact. Optimising for those search queries remains as important as ever.

Actionable steps for SMEs

Audit your existing content

Does this page go further than what anyone could find in five minutes? If not, it needs a rewrite.

Target informational queries in your sector

AI Overviews appear most on informational searches. Write detailed, original content around the questions your customers are already asking Google.

Fix your technical foundations

Check Google Search Console. Make sure pages are indexed, load quickly, and are crawlable. If your web design or site structure is causing issues, that needs addressing first. Technical problems block you from AI search entirely.

Build E-E-A-T signals

Experience, expertise, authoritativeness, and trustworthiness are what Google’s AI systems look for. Author bios, case studies, and detailed service pages all contribute.
