AIO, or AI Optimisation, is the work of making your brand easy for AI assistants to understand, trust and recommend. It covers content structure, third-party listicles, citations and tracking mentions inside answers, not only Google rankings.

Is AIO a replacement for SEO?

No. SEO still matters for Google and for many of the pages AI models cite. AIO is an extra layer. You can rank well and still be missing from ChatGPT or Gemini when a buyer asks for a recommendation.

Does structured data help my brand appear in AI answers?

Not directly. Google states that structured data is not required for generative AI search and that there is no special schema.org markup to add. Keep using it for rich results and general SEO, not as an AIO tactic.

Do I need an llms.txt file?

Google says it ignores llms.txt. No major assistant has committed to reading one as a ranking or citation input. Time spent on it is better spent earning placements on the ranked lists that do get cited.

Can I see AI traffic in Search Console?

Partly. The generative AI performance report shows impressions from AI Overviews and AI Mode by page, country, date and device. It is still rolling out and covers Google only. Bing Webmaster Tools reports Copilot citations separately. Neither covers ChatGPT, Claude or Perplexity.

What should I measure for AIO?

Mention rate on real buyer prompts, whether you are cited with a link or only name-dropped, which competitors appear instead of you, and your AI Overview and Copilot citations from Search Console and Bing.

Guide

Traditional SEO vs AIO

SEO asks whether you rank. AIO, or AI Optimisation, asks whether AI assistants mention you. Those are different jobs. A page can sit on page one of Google and still never appear when someone asks ChatGPT for the best tool in your category.

The two questions, side by side

	Traditional SEO	AIO
The question	Do we rank for this keyword?	Does ChatGPT mention us when a buyer asks for a recommendation?
Where it happens	Google and Bing search results	Answers inside ChatGPT, Gemini, Claude, Perplexity, AI Overviews, AI Mode and Copilot
What you measure	Rankings, clicks, impressions, backlinks	Mentions, citations, share of voice on prompts, competitor gaps
Pages that win	Often your own URLs: category, blog, product, homepage	Ranked listicles and comparison pages, often on someone else's domain
Where the data comes from	Search Console, Ahrefs, Semrush	Search Console generative AI report and Bing AI Performance for the search side, prompt tracking such as LLM Scout for the assistants
A win looks like	Position 1 to 3, more organic sessions	Your brand named, and ideally linked, inside the answer

Why this split exists

Search engines return a list of links. Assistants return an answer. When the answer is self-contained there are fewer outbound clicks, even when more people are asking. Visibility moves inside the reply: were you named, were you cited, did a competitor take the slot.

That is why organic traffic from AI can fall while AI usage grows. Clicks became a weaker signal. Mentions and citations are the ones that match how buyers now decide.

What Google actually says about optimising for AI

Google published a formal guide to generative AI in Search, last updated July 2026. It is worth reading in full because it kills several tactics being sold as AIO right now.

There is no special AI markup. Google states plainly that structured data is not required for generative AI search and there is no schema.org type you need to add. Keep structured data for rich results, not as an AI lever. Google's guide to optimizing for generative AI features
llms.txt files are ignored. Google says so directly in the same guide. So is artificially chunking your pages or rewriting them "for AI".
The technical bar is the normal one. Pages must meet Search's technical requirements, be crawlable and be indexed. Nothing appears in AI Overviews or AI Mode that Google cannot already index. AI features and your website
Content quality is still the lever. Google's line is unique, people-first content over commodity material, which is the same standard it has applied since the helpful content update. Creating helpful, reliable, people-first content

Read this as good news. If nobody can buy their way in with markup, the differentiator is what your content says and who else publishes about you. That is a slower moat, but it is a real one. What the model already believes, before it searches, is covered in what an LLM remembers about your brand.

What you can now measure first-party

Two of the three big surfaces finally report back to publishers. Both are free, and neither existed eighteen months ago. If you want the product names: use an AI visibility tool for assistant mentions, AI overview tracking for Google and Bing, and a free AI visibility check before you buy a larger plan.

Google Search Console

The generative AI performance report shows impressions from AI Overviews and AI Mode, broken down by page, country, date and device. It is still rolling out, so not every property has it, and it covers Google's surfaces only. Generative AI performance report and the launch announcement.

Bing Webmaster Tools

The AI Performance report covers Microsoft Copilot, AI summaries in Bing and selected partner integrations. It gives total citations, average cited pages, the grounding queries that pulled your content in, and page-level citation counts. A June 2026 update added citation share, query intents, topic clusters and period comparison. AI Performance public preview and the June 2026 additions.

The part that stays dark

ChatGPT, Claude, the Gemini app and Perplexity send publishers nothing. No console, no impressions, no citation log. If a buyer asks one of those for a recommendation and a competitor gets named, no first-party tool will ever tell you. Closing that gap means asking the assistants the buyer questions yourself, on a schedule, and recording who gets named. That is the job LLM Scout does.

What to do in practice

Keep doing SEO. Models still pull from pages that rank, especially comparison and list pages.
Check your crawler permissions deliberately, not by accident in an old robots.txt. Blocking OAI-SearchBot removes you from ChatGPT search answers. Google-Extended is different: it governs Gemini model training, not whether you appear in AI Overviews or AI Mode, which follow Googlebot.
Track buyer-style prompts such as "best X" and "alternatives to Y", not only branded vanity queries.
Treat empty mention boxes as the work list. Those are the questions where AI does not know you yet.
Earn places on ranked lists other people publish. Homepages barely get cited.
Turn on the two free reports above so you have a Google and Bing baseline before you change anything.
Report mention rate and share of voice alongside sessions. If you only report sessions, AIO progress looks like a flat line.
