Generative engine optimization (GEO) is the work of making a business easy for AI systems to discover, understand and cite. It rests on the same foundations as SEO: accessible pages, clear answers, evidence, and consistent facts about who you are.
If you want the ChatGPT-specific checklist, read how to rank your website on ChatGPT search. This page covers all the assistants and how to measure across them.
How AI search engines find and select business information
Each assistant works a little differently, but the shape is the same, in four steps:
- The platform interprets the question. It works out what the user wants: a definition, a comparison, a supplier shortlist, a price.
- Search systems retrieve relevant pages. The assistant runs a web search through its own crawler or a partner index. OpenAI documents that OAI-SearchBot surfaces websites in ChatGPT's search features; Anthropic documents Claude-SearchBot as the crawler that improves search results; Google's AI features use Google's ordinary index.
- The system evaluates what it retrieved. It favors passages that answer the question directly, come from a source it can trust, and agree with other sources.
- The AI writes an answer and cites the sources it used. The citation is the prize. A page can rank well on Google and still be skipped here if another page answers the exact question more clearly.
How ChatGPT, Claude and Google AI search differ
ChatGPT searches the web with OAI-SearchBot and shows sources beside its answer. OpenAI says a site that opts out of that crawler will not appear in search answers, though it can still show as a navigational link, and that search changes take about 24 hours after a robots.txt update. GPTBot, OpenAI's training crawler, is a separate setting.
Claude uses web sources and displays citations. Anthropic documents three crawlers: ClaudeBot, which collects content that may contribute to training; Claude-User, which fetches pages when a user asks; and Claude-SearchBot, which indexes for search. Blocking Claude-SearchBot stops indexing for search. Anthropic also notes that blocking its IP addresses is not a reliable opt-out; robots.txt is.
Google's AI Overviews and AI Mode draw on Google's existing Search systems. Google says there are no additional requirements to appear in them and no special structured data to add; a page must be indexed and eligible for a snippet, and the same SEO fundamentals apply. The table below sets the three side by side.
What makes a website more likely to earn an AI search citation?
Eight things, in the order to check them.
1. Make sure AI search crawlers can access your website
Open your robots.txt. Allow OAI-SearchBot and Claude-SearchBot explicitly, and decide separately about the training crawlers (GPTBot, ClaudeBot), which is a policy choice. Check CDN, firewall and security-plugin rules too, because they can block a crawler the robots.txt allows. Keep key pages readable without a login, and fetch one with JavaScript switched off to see what a crawler sees. Allowing a crawler makes pages eligible; it does not make a citation likely.
2. Write pages that answer one clear question
AI systems need to identify what a page says and how it relates to the user's question. Give each page one job, phrase headings as the questions buyers ask, open each section with the answer in a sentence or two, and name the subject ("a WordPress migration", not "it"). Clear structure helps the machine reader and the human one.
3. Add original data, evidence and expert insight
Add figures from your own projects, customer research, product tests or surveys, and say where they came from, when, and what they measure. Quote experts by name and link the original. The Princeton-led study "GEO: Generative Engine Optimization" (accepted to KDD 2024) found that changes to how content is presented could raise visibility in generative engines by up to 40% on its benchmark, and that the effect varied by domain. Evidence is what separates a quotable page from an opinion.
4. Build a clear and consistent brand identity across the web
An assistant has to resolve your business as one entity. Your name, what you do, where you are, who leads it and how to reach you should read the same on your site, your Google Business Profile, directories, social profiles and press. Our company facts page is our own version of this: one list of what we state about ourselves and where each fact comes from.
5. Earn genuine mentions and third-party references
You can publish strong claims about your services; independent sources let a customer, and an assistant, verify them. Useful references include trade publications, professional associations, client case studies with permission, industry reports and credible review platforms. Never manufacture mentions; fake reviews and seeded discussions do not create authority and can breach the rules.
6. Use structured data to clarify important details
Structured data labels what a page is: an organization, an article with an author and dates, an FAQ, a product. Use it for content that is visible on the page; Google's guidance says to make sure structured data matches the visible text, and that no special schema is needed for AI features. Structured data describes a page; it does not rescue a weak one.
7. Keep important content accurate and up to date
For time-sensitive topics, state the date or period the information covers. If a statistic comes from a 2024 report, call it a 2024 finding. Show an updated date on guides, retire outdated sections, and revisit the pages that matter on a schedule. An answer engine serving today's question prefers a page that says when it was last checked.
8. Build topic depth instead of isolated articles
A cluster of connected pages on one topic (the service, the cost, the comparison, the how-to, the FAQ) signals that a site knows the subject. Google's guidance on helpful content describes what its systems look for as experience, expertise, authoritativeness and trust, with trust the most important, and strongly encourages accurate bylines. Depth with named authors is how a smaller business earns that trust.
How to improve your visibility on each platform
Platform by platform, the practical checks:
ChatGPT
Confirm OAI-SearchBot can crawl the pages you want found; check robots.txt, CDN and firewall rules. Publish useful service pages, original resources and clear business information, keep key pages open without a login, and support claims with evidence. Allowing the crawler makes pages eligible; it does not make a citation certain. The nine-point checklist is in our guide to ranking on ChatGPT search.
Claude
Claude shows citations beside its answers. Make pages clear and easy to verify: descriptive headings, plain answers, primary sources linked. Check that Claude-SearchBot is allowed in robots.txt on every subdomain you want indexed, as Anthropic's help page describes, and keep supporting pages current. Sharing real expertise in professional communities where your buyers ask for advice helps too.
Google AI Overviews and AI Mode
Google's AI features rely on its existing Search systems, so pages must meet Google's technical requirements and qualify to appear with a snippet. Do the SEO basics well: crawlable pages, useful internal links, helpful content, structured data that matches the visible text. Skip tactics Google does not recommend: Google says there is no special schema or file to add for AI features. Our guide to zero-click SEO explains how to read the traffic effect.
How to measure AI search visibility
Traditional reports track rankings, impressions, clicks and conversions. They miss a platform that mentions you without sending a visitor. Combine three checks:
- AI referral traffic in analytics. Look for sessions whose source is an assistant's domain. If the volume justifies it, group them into their own channel and track engaged sessions, inquiries and calls. Remember that someone may hear of you in an assistant and arrive later through Google or by typing your name.
- Prompt testing. Write a fixed list of buyer questions across learning, comparing and buying intent. Run them across ChatGPT, Claude and Google's AI features at regular intervals, from a consistent location, and record whether you appear, which competitors appear, which pages are cited and whether the facts are right. Answers vary with wording, location and product updates, so a single test proves nothing; a monthly series shows a trend.
- Crawler activity and technical health. Server logs show whether the search crawlers visit, which URLs they request and what status codes they get. A visit is not a citation, but it rules out access problems.
A practical six-week GEO action plan
You do not need to change the whole site at once:
- Week 1: access and indexation. Review robots.txt, noindex tags, sitemap coverage, CDN rules and the response of key pages. Confirm the search crawlers can reach them.
- Weeks 2 and 3: priority pages. Pick the high-value service pages and resources. Rewrite unclear sections, answer the buyer's question near the top, add evidence, remove outdated claims.
- Week 4: brand information. Check business details across your site and the main third-party profiles. Improve the about page, author information, case studies and industry listings.
- Week 5: supporting content. Publish or improve comparison pages, technical guides, FAQs and case studies that answer real customer questions, with internal links between them.
- Week 6: measurement. Create the baseline prompt list, review AI referral traffic, inspect crawler logs and record which pages and competitors appear. Plan the next round from the findings.
Common mistakes that limit AI search visibility
The mistakes we see most:
- Blocking search crawlers by mistake. A broad robots.txt rule or a firewall setting from 2023 can keep a platform from reading important pages. Check access before blaming content.
- Writing for algorithms instead of customers. Repeated keywords and stiff phrasing make a page less useful, not more quotable.
- Publishing unsupported claims. "The leading provider" and "the fastest solution" need evidence; replace them with checkable detail or drop them.
- Treating structured data as a shortcut. It describes a page; it cannot fix weak content, wrong facts or blocked access.
- Manufacturing brand mentions. Fake reviews and seeded discussions do not build authority and can break the rules.
- Measuring once. AI answers vary. Check the same buyer questions on a schedule.
Conclusion
Getting cited in ChatGPT, Claude and Google's AI answers is not a hidden trick. It is making your business easy to discover, your information easy to understand and your claims easy to verify: allow the search crawlers, keep pages technically sound, answer real questions with evidence, keep your facts consistent, earn real mentions, and measure the prompts that matter. AI search is still changing, and no method can promise a citation for every query.
