AI Search Optimisation: How to Rank in AI Answers
AI search optimisation is the practice of making your website easy for AI engines to crawl, parse, trust and quote. Where SEO wins you a ranked link, AI search optimisation wins you a citation inside the answer itself - the place people now actually look.
What is AI search optimisation?
AI search optimisation is the practice of making your website easy for AI engines - ChatGPT, Google AI Overviews, Perplexity and Gemini - to crawl, parse, trust and quote. It combines classic technical SEO with AI-specific signals: structured data, entity clarity, answer-first content and AI crawler access. Where SEO wins a ranked link, it wins a citation inside the answer itself.
Why AI search changed the rules
Classic search shows ten links and lets the user choose. AI search reads the web, decides what’s true, and returns one synthesised answer with a handful of citations. That collapses the funnel: if you’re not in the answer, you’re not in the consideration set at all. Ranking eleventh used to mean less traffic - now, not being cited can mean no traffic.
The good news: the signals AI engines rely on are largely mechanical, and most sites are failing them for boring, fixable reasons - blocked crawlers, missing schema, ambiguous entities, and content that buries the answer six paragraphs down.
How to optimise for AI search
Work in this order - there’s no point polishing content if the crawlers can’t reach it in the first place.
- Let the AI crawlers in: check robots.txt for GPTBot, ClaudeBot, PerplexityBot, OAI-SearchBot and Google-Extended. A single Disallow can make you invisible to an entire engine.
- Add Organisation (or LocalBusiness) structured data with a consistent name, logo, description and sameAs links.
- Lead with the answer: open each section with one direct, quotable sentence, then expand. AI extracts the first clear answer it finds.
- Add FAQ structured data for genuine questions your audience asks.
- Keep entities unambiguous - the same business name, description and location everywhere on the web.
- Publish an llms.txt summarising your site and pointing to your key pages.
- Earn presence in the sources AI trusts most: Wikipedia, Wikidata and established industry sites.
You can check most of this in one pass with a free AI SEO audit, and fix your crawler rules with the robots.txt generator.
How to optimize content for AI search
(Written “optimize” in US English - it’s the same work.) The section above is about access and signals; this one is about the writing itself, which is where most pages actually lose the citation. To optimize content for AI search:
- Lead every section with a direct, quotable answer of one or two sentences, then expand - a model lifts the first clear answer it finds.
- Shape headings as the exact questions people ask, so the match is unambiguous.
- Keep each page focused on one topic and answer it completely, so an engine can satisfy the query from your page alone.
- State facts plainly and unambiguously - AI extracts claims, so make clear ones it can attribute to you.
- Pair the prose with FAQ structured data so your question-and-answer pairs are machine-readable, not just human-readable.
How to measure AI search visibility
“Are we visible in AI?” sounds unmeasurable, but it breaks down into three concrete layers you can actually track:
1. Access - can each engine reach you?
Per-engine crawler permissions from your robots.txt. This is binary and the most common silent failure: block PerplexityBot and you simply don’t exist there.
2. Understanding - can they identify you?
Structured data, entity consistency, and whether you appear in the knowledge sources AI leans on (Wikipedia, Wikidata). No entity, no confident citation.
3. Citation - are you actually quoted?
The end result: your brand appearing in generated answers for the questions that matter to your business.
The AI Visibility Checker scores the first two instantly - showing which engines can reach you, whether you have a Wikipedia and Wikidata presence, and exactly what’s holding you back.
The five most common mistakes
- Blocking AI crawlers by accident - usually a blanket Disallow copied from an old robots.txt.
- No Organisation schema, so AI can't tell which company you are.
- Burying the answer under an intro, so there's nothing quotable to extract.
- Inconsistent brand details across your site, LinkedIn and directories.
- Treating AI search as a one-off project rather than something to monitor as your site changes.
That last one matters more than it sounds: a redeploy that drops your schema or flips a robots rule can quietly remove you from AI answers. Daily monitoring catches it before your traffic does.
Where GEO and AEO fit in
AI search optimisation is the umbrella. Generative Engine Optimisation (GEO) is the part focused on being cited by generative engines, and Answer Engine Optimisation (AEO) is the part focused on structuring content so a single direct answer can be extracted. In practice they share most of the same work - see GEO vs SEO for how it all relates to classic search.
