What Is AI Search Optimisation and Do I Need It?
AI search optimisation gets your business cited in ChatGPT, Gemini, Perplexity, and AI Overviews. AI visitors convert at 27%.
AI search optimisation gets your business cited, quoted, and recommended by AI platforms like ChatGPT, Gemini, Perplexity, and Google AI Overviews. You likely need it. 48% of Google queries now show AI Overviews. AI search visitors convert at 27% versus 2.1% from traditional organic search.
How AI search differs from traditional search
Traditional SEO ranks blue links on a results page. AI search optimisation focuses on being the answer. AI platforms cite businesses when users ask questions. Instead of "click this link", AI gives a direct answer and names sources. If your business is not one of those sources, you are invisible to a growing share of searchers.
The shift is significant. Google's AI Overviews appear for nearly half of all queries. ChatGPT processes over 37.5 million queries per day. Users ask AI for recommendations, comparisons, and local services.
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 pay attention. Three groups gain the most. B2B companies where buyers use AI for research. Local services where AI replaces "near me" search. Professional services where AI recommendations carry significant weight.
If your competitors appear in ChatGPT and you do not, the gap will widen. The earlier you optimise, the harder it becomes for competitors to displace you. AI models tend to reinforce existing citations.
