Short answer: You rank in ChatGPT and AI search by being the page these tools find and trust when they search the web. That means ranking well in Bing and Google, letting AI crawlers reach your site, writing pages that answer questions directly with specific facts, and being described consistently on other trusted sites. Nobody controls AI answers, but you can make yourself far easier to find and quote.
Key takeaways
- For questions about products, services and local businesses, AI tools usually run a live web search and quote from what comes back. That is the part you can influence.
- ChatGPT search, Copilot and Google AI Overviews pick sources from search indexes, so ranking in Bing and Google is still the foundation.
- Pages get quoted when each section answers one question in its first sentence and adds specifics nobody else has.
- What other websites say about you decides whether AI tools recommend you, not only what your own site says.
- Check robots.txt, CDN bot settings and Bing Webmaster Tools. Many sites block AI crawlers without knowing it.
If ChatGPT recommends your competitors and not you, these are the levers that decide whether you show up. Nobody can promise you a place in an AI answer, since the same question asked twice can produce different results, but you can improve the odds with work that also helps your normal search traffic.
How do ChatGPT and other AI tools pick their sources?
AI assistants answer from two places: what the model learned in training, and live web results they fetch when a question needs current or specific information. Training data changes only with new models, so for questions about services, products or local businesses the live search is where your opportunity sits.
- ChatGPT search uses OpenAI's own crawler, OAI-SearchBot, alongside third-party search providers, with Bing long known as a major one.
- Microsoft Copilot is built on Bing's index.
- Google AI Overviews and AI Mode draw on Google's own index.
- Perplexity runs its own crawler, PerplexityBot, combined with other search sources.
The tool typically rewrites your question into several shorter searches and picks sources from what comes back. Asked for "a good Klaviyo agency for a small skincare brand in Germany", an assistant might search "Klaviyo agency Germany" and "email marketing agency skincare reviews", and list the agencies that appear more than once. What decides the outcome is whether you show up across those searches, and whether other sites describe you in a way that matches the question.
Does ranking in Google and Bing still matter for AI search?
Yes. Ranking in classic search is the biggest single factor you control, because ChatGPT, Copilot and Google AI Overviews all choose their sources from search indexes. A page that is not indexed, or sits on page five, is rarely the page an AI tool quotes.
Page one does not guarantee a citation, but in our experience the overlap is large: pages that earn steady organic clicks tend to appear in AI answers on the same topics.
Bing deserves more attention than it gets. Its index sits behind Copilot and has long fed ChatGPT search, yet we regularly see sites indexed well in Google with gaps in Bing: missing pages, outdated titles or crawl errors nobody has looked at. Fixing those is cheap.
The common mistake is treating AI search as a separate project with its own budget and tactics. If the site has crawling problems, thin pages or no authority, AI tools skip it for the same reasons Google does. Solid SEO services are the base layer, and the AI-specific work sits on top. It is largely the job described in what an SEO agency is and does, with more attention on Bing, passages and mentions.
What makes a page easy for AI to quote?
A page is easy to quote when each section answers a specific question in its first one or two sentences, uses descriptive headings and includes concrete facts the AI cannot find elsewhere. AI tools lift passages, not whole pages, so each section has to make sense on its own.
If your answer is buried in paragraph nine, the assistant will often pick a competitor's page where the answer sits right under the heading. "Shopify SEO usually takes four to six months to show clear results" is quotable. "Many factors influence how long SEO takes" is not. Specifics such as ranges, steps, locations and dates give the AI something concrete to say, and original information (your own process, examples and opinions) gives it a reason to credit you rather than the fifty pages saying the same thing.
The improved opening names the service, the customer and the location in one sentence, so it matches a real question and is easy to cite. Structured data and llms.txt files are cheap extras, not levers that force citations.
AI SEO services built on solid search foundations
We test the questions your buyers ask in ChatGPT, Perplexity and Google, find out who gets cited and why, then fix access, content and authority in that order. No tricks, and no promises we cannot keep.
See our AI SEO servicesHow do mentions on other websites affect AI recommendations?
Mentions on other websites strongly influence whether AI tools recommend you, because assistants summarise what independent sources say. If comparison articles, review platforms, industry press and forums describe you consistently, you are far more likely to appear in "best" and "which should I choose" answers.
For a question like "best CRM for a small law firm", your own page saying you are the best is weak evidence. A comparison article on an industry site, detailed reviews on the platforms your sector uses and a thread where real users recommend you are much stronger. That is how you can rank first in Google while ChatGPT recommends three competitors.
Consistency matters as much as volume. If one directory calls you a "web design studio", another a "digital agency" and your site says "SEO consultancy", the AI gets a muddled picture. Use the same short description of who you are, what you offer and where you work on every profile.
Avoid buying placements in low-quality "top 10" lists or posting fake reviews; it damages the trust you are trying to build. Earned mentions through expert comment, original data and genuine news take longer, which is why they carry weight. Our content marketing services focus on the kind of material other sites want to reference.
What technical settings stop AI tools from finding you?
The settings that most often keep pages out of AI answers are robots.txt rules that disallow AI search crawlers, CDN or firewall bot protection that blocks them silently, content that only appears after JavaScript runs, and gaps in Bing's index. Any one of these can hide a good page.
Many sites copied a "block all AI bots" rule without checking what each crawler does.
| Crawler | Who runs it | What it is for |
|---|---|---|
| OAI-SearchBot | OpenAI | Finding pages for ChatGPT search. Block it and you are unlikely to be cited there. |
| GPTBot | OpenAI | Collecting content for training future models. Separate from search. |
| PerplexityBot | Perplexity | Indexing pages for Perplexity's answers. |
| Bingbot | Microsoft | Bing's index, which feeds Copilot and ChatGPT search. |
| Google-Extended | Controls Gemini training use only. AI Overviews follow normal Googlebot rules. |
A sensible default for businesses that want to be found: allow OAI-SearchBot, PerplexityBot, Bingbot and Googlebot. Allowing training bots is a separate decision, and blocking them does not block search.
Two blocks will not show up in robots.txt. First, some CDN and security services, Cloudflare among them, offer settings that can block AI crawlers, so check your bot management settings and look for the crawler names above in your logs. Second, many AI crawlers do not run JavaScript the way a browser does. View the page source (not the inspected page) and search for a key sentence; if it is not in the raw HTML, assume some AI tools cannot read it. Our technical SEO services include this kind of rendering check.
Finally, verify your site in Bing Webmaster Tools (you can import it from Google Search Console), submit your XML sitemap and review the index and crawl error reports. IndexNow, supported by many CMS platforms and SEO plugins, tells Bing straight away when a page is added or changed.
Frequently asked questions
Not in the organic answer. There is no submission form or paid route into what the assistant chooses to cite, and anyone selling a guaranteed placement is overpromising.
Technical fixes, such as unblocking a crawler, can show results within weeks once pages are recrawled. Content and authority work follows a similar timeline to normal SEO, which we cover in how long SEO takes to work.
Ask ten questions your buyers ask in a temporary chat each month and note whether you appear, who appears instead and which sites are cited. Also watch referral visits from chatgpt.com, perplexity.ai and copilot.microsoft.com in your analytics, and judge the pattern over a few months rather than one run.
That is a business choice. Blocking GPTBot stops your content being collected for training, but according to OpenAI it does not remove you from ChatGPT search as long as OAI-SearchBot is allowed.
No. GEO (generative engine optimisation) and AEO (answer engine optimisation) are newer labels for making content easy for AI tools to find and quote. In practice they overlap heavily with SEO, so treat them as a focus within it.
What to do next
Start with what you can check this week, then build the slower work on top.
- Check robots.txt, your CDN bot settings, the raw HTML of key pages and your Bing Webmaster Tools index report.
- Rewrite the opening of your three most important pages so the first sentence answers the question a buyer would ask.
- For a second opinion, ask for a free written AI search and SEO audit. We send it within 48 hours and tell you honestly which fixes are worth doing first.
