How to Rank in AI Search Engines: What Actually Works

To rank in AI search engines, make sure their crawlers can reach your site, keep your pages indexed in normal search, and publish clear, specific, expert content about what you do and where. There is no secret file or special markup: Google, OpenAI and Perplexity all point back to the same basics of access, clarity and genuine expertise.

AI search covers Google's AI Overviews and AI Mode, ChatGPT search, Perplexity, Copilot and Gemini. They answer the question directly and cite a handful of sources, so being one of those sources matters more than ever.

How AI search engines choose what to cite

Each assistant searches an index of the web, reads the most relevant pages and summarises them, usually with links to the pages it used. You cannot buy a place in these answers. You can make your pages the easiest, most trustworthy source for the questions your customers ask.

Google is explicit that its AI features use the same foundations as normal search. It says there are no additional requirements or special optimisations needed to appear in AI Overviews or AI Mode: a page must be indexed and eligible to be shown with a snippet. So the first rule of ranking in AI search is to rank in ordinary search.

Step 1: Let the AI crawlers in

Many sites block AI crawlers by accident, through a security plugin, a firewall rule or a copied robots.txt file. Check yours.

• ChatGPT search uses a crawler called OAI-SearchBot. OpenAI recommends allowing OAI-SearchBot in robots.txt if you want to appear in ChatGPT search results, and notes that sites which block it will not appear in its search answers. Its separate GPTBot crawler is for training models; you can block that one without affecting search.
• Perplexity uses PerplexityBot, which it says is designed to surface and link websites in its search results and is not used to train foundation models. It recommends allowing it in robots.txt.
• Google uses Googlebot for both normal search and AI features. Its Google-Extended setting controls use of your content in some of its other AI systems, but it does not remove you from Search.

A quick test: open yoursite.com/robots.txt and look for lines that disallow these crawlers. If your site sits behind a firewall or CDN, check its bot settings too, because some can block AI crawlers.

Step 2: Make sure your pages are indexed and snippet-eligible

If Google cannot index a page, it cannot appear in AI Overviews. In Google Search Console:

• Check Page indexing for important pages marked as not indexed.
• Use URL Inspection on your key service pages.
• Remove accidental noindex or nosnippet tags. Google lists these as the controls that limit what appears in Search and AI features.

Microsoft's Copilot draws on Bing's index, so it is also worth verifying your site in Bing Webmaster Tools and submitting your sitemap there.

Step 3: Write pages that answer questions directly

AI assistants quote passages that answer a question cleanly. Pages that bury the answer under marketing language are harder to use.

• Answer first. Open each page or section with two or three sentences that directly answer the question, then explain.
• Use the questions as headings. "How much does an EICR cost in Essex?" is easier to match than "Our pricing philosophy".
• Be specific. Name your services, locations, prices or price ranges, timescales and the types of customer you serve. Vague pages give an AI nothing to cite.
• Keep facts consistent. Your business name, address, phone number, services and opening hours should match on your website, Google Business Profile and directories. Conflicting details make an AI less confident about recommending you.

Step 4: Show real expertise

Google's guidance on helpful content asks whether content provides original information, research or analysis, and whether it is written or reviewed by someone who demonstrably knows the topic. AI systems lean on the same signals when choosing trustworthy sources.

In practice:

• Add author names and short bios to articles, especially on technical or regulated topics.
• Publish things only you can: real project examples, photos of your work, data from your own experience, honest comparisons.
• Cite official sources for any facts, prices or rules you mention.
• Keep important pages up to date and show the date they were last reviewed.

Step 5: Build mentions beyond your own website

When an assistant decides which businesses to recommend, it often draws on what other sites say about you as well as what you say about yourself.

• Keep your Google Business Profile complete and collect genuine reviews.
• Make sure you are listed accurately on the main directories for your industry and country.
• Earn mentions in local press, industry associations, partner websites and podcasts.
• Answer questions in places your customers ask them, such as industry forums, under your own name.

Step 6: Check what AI tools say about you

Ask ChatGPT, Perplexity, Gemini and Google's AI Mode the questions your customers would ask, such as "best web developer for a small business in Manchester" or "who installs EV chargers in Grays". Note:

• whether you are mentioned
• which sources they cite instead of you
• any facts they get wrong about your business

The cited sources show you what kind of content wins. Wrong facts usually trace back to an out-of-date directory listing or an old page on your own site, which you can fix.

What doesn't work

• Special "AI files" or secret markup. Google says you do not need new machine-readable files, AI text files or special schema to appear in its AI features.
• Mass-produced AI content. Thin pages written to target every possible phrase are what search engines try to filter out, and AI answers are built on top of search.
• Keyword stuffing. Assistants summarise meaning; repeating a phrase does not help.
• Buying links or reviews. It risks penalties in normal search, which removes you from AI answers too.

How AI search fits with normal SEO

AI search optimisation, sometimes called GEO or AEO, is not a replacement for SEO. It is SEO done with more attention to clear answers, consistent facts and visible expertise. The same work that makes a page rank well in Google, explained in our SEO and social media marketing service, is what makes it worth citing in an AI answer. A fast, well-structured site helps both, which is why we build these foundations into every website we develop.
