What Is AI Search Optimisation and Do I Need It?
AI search optimisation gets your business cited in ChatGPT, Gemini, Perplexity, and AI Overviews. With 48% of queries triggering AI results and AI visitors converting at 27%, most businesses need it.
AI search optimisation is the practice of getting your business cited, quoted, and recommended by AI platforms like ChatGPT, Gemini, Perplexity, and Google AI Overviews. Yes, you likely need it — 48% of Google queries now show AI Overviews, and visitors arriving from AI search convert at 27% compared to 2.1% from traditional organic search.
How AI search differs from traditional search
Traditional SEO focuses on ranking blue links on a search results page. AI search optimisation focuses on being the answer — the business that AI platforms cite when users ask questions. Instead of "click this link and find out", AI gives users a direct answer and names sources. If your business isn't one of those sources, you're invisible to a growing share of searchers.
The shift is significant. Google's AI Overviews now appear for nearly half of all queries, and standalone AI tools like ChatGPT process over 37.5 million queries per day. Users are asking AI for recommendations, comparisons, and local services — and expecting direct answers.
What AI search optimisation involves
AI search optimisation combines several disciplines:
- Technical access — ensuring AI crawlers (GPTBot, ClaudeBot, PerplexityBot) can access your site via robots.txt configuration
- Structured data — adding schema markup so AI platforms understand your content's meaning
- Content clarity — writing clear, factual content with definitive answers that AI can extract and cite
- Platform submission — submitting to Bing (which feeds ChatGPT), Google Business Profile, and knowledge bases
- Brand authority — building consistent mentions across authoritative sources, which AI models use to determine trustworthiness
The business case in numbers
| Metric | Value |
|---|---|
| Google queries showing AI Overviews | 48% |
| AI search visitor conversion rate | 27% |
| Traditional organic conversion rate | 2.1% |
| ChatGPT daily queries | 37.5 million |
| AI referral traffic growth (YoY) | 1,300% |
Who needs AI search optimisation most
Any business that relies on being found online should be paying attention. But three groups have the most to gain: B2B companies (where buyers increasingly use AI for research), local services (where AI is replacing "near me" search), and professional services (where AI recommendations carry significant weight).
If your competitors appear in ChatGPT and you don't, that gap will widen. The earlier you optimise, the harder it becomes for competitors to displace you — AI models tend to reinforce existing citations.
