How to Optimise Your Website for AI Search like ChatGPT

The short answer: to show up in AI search results on ChatGPT, Perplexity, and Google AI Overviews, your website needs to be structured so that large language models (LLMs) can read, understand, and trust it. This is called GEO — Generative Engine Optimisation (sometimes called LLM SEO). It is different from traditional SEO, though the two overlap. Here is exactly how to do it.

Why AI Search Is Different from Google

When someone searches on Google, they scroll through a list of blue links. When someone asks ChatGPT or Perplexity a question, they get a single, confident recommendation. If your business is not in that recommendation, you are invisible — no second page, no lucky click.

AI assistants pull information from publicly crawlable web pages, structured data, authoritative citations, and increasingly from real-time web browsing. The businesses that get recommended are the ones that have given AI the clearest, most trustworthy signal about what they do, who they serve, and why they are the best answer.

Step 1 — Write Directly Answerable Content

AI search rewards pages that directly answer specific questions. The format that works best:

Step 2 — Add Proper Schema Markup

Schema.org structured data tells AI crawlers exactly what your page is about. For most businesses, the most important schema types are:

If your site is built on a CMS like WordPress, plugins can handle basic schema. For custom sites, a developer needs to add JSON-LD to the page head.

Step 3 — Build Genuine Authority Signals

AI models are trained on, and increasingly browse, the broader web. They trust businesses that are mentioned and linked to from reputable sources. To build this:

Step 4 — Make Your Site Technically Clean

If AI crawlers cannot read your site, none of the above matters. Technical basics to check:

Step 5 — Check How AI Actually Sees You Right Now

Before spending time on fixes, find out where you actually stand. Ask ChatGPT and Perplexity questions your customers would ask — include your city and category — and see if your business comes up. Take note of which competitors are recommended and why their pages might be ranking.

FAQ

Is GEO the same as SEO?

They overlap but are not identical. Traditional SEO focuses on ranking in Google's list of links. GEO (Generative Engine Optimisation) focuses on getting your business recommended by AI assistants like ChatGPT and Perplexity. Many fundamentals — clear content, structured data, authority signals — help both, but GEO also requires specific steps like llms.txt files, FAQ schema, and directly answerable copy that traditional SEO alone does not cover.

How long does it take to see results in AI search?

There is no fixed timeline, and any specific number would be misleading. AI models are updated at varying intervals. However, fixing technical issues and adding structured data can be picked up relatively quickly by crawlers that feed AI systems. Building authority through citations and mentions takes longer — weeks to months, as with traditional SEO.

Do I need a new website to rank on AI search?

Not necessarily. Many existing sites can be improved with schema markup, content restructuring, and technical fixes without a full rebuild. That said, if your current site is slow, JavaScript-heavy, or structurally confusing, a clean rebuild often produces faster results than patching an old site.

What is an llms.txt file and do I need one?

An llms.txt file is a plain-text document placed at the root of your website that gives AI crawlers a clean, concise summary of what your site contains and who it is for — similar to how robots.txt guides traditional crawlers. It is an emerging standard. Adding one is a low-effort step that signals AI-readiness and is worth doing now while it is still uncommon.

Can a small or local Indian business realistically rank in AI search?

Yes — and in some ways local businesses have an advantage. When someone asks an AI assistant «who is the best [service] in [city]», the AI is looking for the most clearly described, most credible local answer. A well-structured local business page with proper schema, a verified Google Business Profile, and genuinely helpful content can outperform larger brands that have not optimised for AI-specific signals.
