AI answers cite pages their search systems can crawl, index and trust, so getting cited in AI Overviews, ChatGPT or Perplexity starts with SEO done well. Let Googlebot, Bingbot, OAI-SearchBot and PerplexityBot reach your site, put a clear, sourced answer near the top of each page and keep your business facts the same everywhere, then track citations in Search Console and Bing Webmaster Tools. Google says no special file or markup is needed, and no one can guarantee a citation.
Why AI answers don’t mention your business
When Google, ChatGPT, Copilot or Perplexity searches the web to answer a question, it builds the answer from pages it finds and links the ones it used. Each has its own crawler and index, but every page faces the same three tests: can the system reach it, can it understand it, and is it the clearest answer to the question? If AI answers never mention you, one of those three is usually missing.
How do AI Overviews choose which pages to cite?
Google says its generative AI features are rooted in its core Search ranking and quality systems and highlight content from its Search index. To be shown as a supporting link in AI Overviews or AI Mode, a page must be indexed and eligible to appear in Google Search with a snippet. Google also says there are no additional requirements or special optimizations: you don’t need new machine-readable files, AI text files or special markup.
Both features may use what Google calls “query fan-out”: running several related searches across subtopics while the answer is written, which lets them show a wider set of links than a classic results page. Google says this gives more types of sites a chance to appear, so a page that clearly answers one part of a bigger question can still earn a link.
In practice, the way to get cited in AI Overviews is to do the basics of SEO well. If your pages aren’t indexed or don’t rank for anything, fix that first. Our SEO services for Google and AI search start with a crawl of your site and your Search Console data for exactly this reason.
Are you blocking the crawlers AI search uses?
Each AI search tool reads the web with its own crawler, and you allow or block each one in robots.txt. Google and OpenAI separate crawling for search from use of your content for AI training, so you can allow one and refuse the other. Check your firewall and CDN settings too: Google recommends that crawling is allowed “in robots.txt, and by any CDN or hosting infrastructure”.
| Crawler (robots.txt name) | Whose | What it’s for | If you block it |
|---|---|---|---|
| Googlebot | Google Search and all its features, which include AI Overviews and AI Mode | Your pages can’t be crawled for Google Search, so they can’t appear in its AI features either | |
| Google-Extended | Not a separate crawler but a robots.txt control: whether Google may use your content to train future Gemini models and for grounding in Gemini Apps and Vertex AI | Google says it doesn’t affect inclusion in Google Search and isn’t a ranking signal | |
| Bingbot | Microsoft | Bing’s crawler; Bing Webmaster Tools reports how pages are crawled and indexed across Microsoft’s search experiences, including Copilot | Bing respects robots.txt, so blocked pages aren’t crawled for Bing or for the Copilot answers that draw on it |
| OAI-SearchBot | OpenAI | Showing websites in ChatGPT’s search features | Your site isn’t shown in ChatGPT search answers, though it can still appear as a navigational link |
| GPTBot | OpenAI | Crawling content that may be used to train OpenAI’s foundation models | Your content isn’t used for training; OpenAI says each setting is independent, so OAI-SearchBot is unaffected |
| PerplexityBot | Perplexity | Surfacing and linking websites in Perplexity’s search results; not used to train AI foundation models | Perplexity recommends allowing it if you want your site to appear in its results |
Changes aren’t instant: OpenAI says its search systems take about 24 hours to adjust after a robots.txt update, and Perplexity says up to 24 hours. For Google, also check that your site is included in Search generative AI features in Search Console; Google’s guide says that is required to be eligible.
Write pages an AI answer can quote
Once crawlers can reach you, the page itself decides whether you’re cited. AI answers summarize and link, so make your answer easy to find and easy to trust:
- Answer first. Put a direct two- or three-sentence answer under each main heading, then the detail.
- Use your buyers’ words in headings, and tables for comparisons. Bing says clear headings, tables and FAQ sections make content easier for AI systems to reference accurately.
- Be specific and show sources. Name places, timelines, steps and numbers where you can, and link to where outside facts come from. Bing notes that examples, data and cited sources help build trust when content is reused in AI answers.
- Add what only you can say: your process, your examples, what you’ve learned on real projects. Google says content people find unique, compelling and useful will likely matter more for AI search in the long run than any other suggestion in its guide, and warns against recycling what others have already said.
- Keep it in text. Important content belongs in the page’s text, not only in images or video, and any structured data should match what visitors see.
- Keep it current. Update pages when facts change. Bing suggests IndexNow, which notifies participating search engines when content is added, updated or removed.
Keep your business facts the same everywhere
When an assistant describes your company, it can draw on your website and on other pages about you. If your name, address, services or hours differ between your site, LinkedIn, Google Business Profile and directories, you give it conflicting facts to choose from. A short checklist:
- One spelling of your business name, one address and one phone number, used everywhere.
- The same services and areas served on your site, LinkedIn and directory profiles.
- An About page that says, in plain text, who you are, where you work and what you do.
- Your Google Business Profile, and Merchant Center if you sell online, kept up to date. Google lists both among its recommendations for AI features, and says Business Profiles can help your products and services show up in AI responses.
- Profiles on the directories and review sites your buyers actually use, matching your site.
- Mentions earned honestly. Google says seeking inauthentic mentions across the web isn’t as helpful as it might seem.
How do you know if AI answers cite you?
| Where to look | What it shows |
|---|---|
| Google Search Console: Performance report | Traffic from AI Overviews and AI Mode is included in your overall search traffic, under the “Web” search type |
| Google Search Console: Generative AI performance report | The report Google points to for how your content performs in its generative AI features on Search and Discover |
| Bing Webmaster Tools: AI Performance (public preview since February 2026) | Total citations, average cited pages, grounding queries and citations per page, across Microsoft Copilot, AI-generated summaries in Bing and select partner integrations |
Bing describes grounding queries as the key phrases its AI used when it retrieved your content. They make a useful list of questions your pages should answer clearly. For ChatGPT and Perplexity, watch the visits they refer in your analytics, and once a month ask each assistant the questions your buyers ask and note whether you’re cited. If your search traffic has fallen at the same time, see why website traffic drops before you change anything.
What doesn’t help
- An llms.txt file for Google. Google says Search doesn’t use llms.txt or other AI text files; keeping one for other services neither helps nor harms your visibility in Google Search.
- Special schema for AI. Google says structured data isn’t required for its generative AI features and there is no special markup to add. Keep the structured data you have accurate and matching the page.
- Chopping pages into fragments. Google says there is no need to break content into tiny pieces for AI to understand it.
- Hidden text or hidden instructions for AI tools. Google tells site owners to follow the same Search policies for AI features as for the rest of Search, and says its AI features depend on the systems that block spam as well as those that rank content. Write for the people reading the page.
- A guaranteed citation. Google says indexing and serving aren’t guaranteed. As our guide to affordable SEO services explains, be wary of anyone who promises guaranteed rankings.

Frequently asked questions
Do I need an llms.txt file?
Not for Google. Google says Search doesn’t use llms.txt or other AI text files, and that keeping one for other services neither helps nor harms your visibility in Google Search. If a tool you care about reads the file, it’s fine to keep one, but spend your time first on crawlable pages with clear answers, because that is what AI answers draw on.
Does schema markup help me get cited in AI answers?
Not on its own. Google says structured data isn’t required for its generative AI features and there is no special schema to add. Structured data still helps describe your business, services and articles, so keep it, and make sure it matches the visible text on the page. The answer on the page matters more than the markup around it.
How long does it take to show up in AI answers?
There is no fixed timeline, and no one can guarantee a citation. After you unblock a crawler, OpenAI says its search systems take about 24 hours to pick up a robots.txt change, and Perplexity says up to 24 hours. Your pages then still have to be crawled, indexed and judged a strong answer, which, as with other SEO work, takes weeks to months.
Will blocking AI training bots keep me out of AI search?
It depends on which one you block. Blocking GPTBot or Google-Extended limits the use of your content for AI training without removing you from ChatGPT search or Google Search: OpenAI says its settings are independent, and Google says Google-Extended doesn’t affect Search. Blocking OAI-SearchBot, Googlebot, Bingbot or PerplexityBot can keep you out of the results those AI answers draw on.
