To get cited by Grok, find the web pages Grok itself cites for your buyers' questions, whose top sources in our scans were largely different from other engines', and get onto them; then publish plain how-to and comparison pages, and keep a public X account that states your facts. X's help center says Grok decides whether to search public X posts and the web for each question, and in our scans x.com was not among the five sites Grok cited most.
How does Grok find sources?
Grok has two ways to look things up. X's help center says it can decide, question by question, whether to search public posts on X and whether to run a real-time web search. xAI's developer documentation describes the same pair as tools:
- Web Search lets Grok search the web in real time and browse pages to pull out the information it needs.
- X Search lets Grok run keyword and semantic searches of X posts, search for users and fetch whole threads.
The documented loop is the same for both. Grok works out what information the question needs, decides whether to call a tool or answer, runs the search, and keeps going until it has enough, then returns an answer with citations where they apply.
Two details from xAI's citation documentation matter if you measure Grok:
- The full source list is not the cited list. Through the API, Grok returns every URL it encountered while searching, and xAI says not all of them are referenced in the final answer. A page can be read and still not be cited.
- Citations are the model's choice. Even with inline citations switched on, xAI says the model decides when and where to cite, so not every answer carries them.
One X setting matters for brands. X's help center says that making an account private keeps its posts from being surfaced in response to Grok users' questions. A brand that wants its posts found needs a public account.
The xAI and X pages cited here do not name a Grok web crawler or a robots.txt token for it, so, unlike the crawler pages from OpenAI, Anthropic and Perplexity, they give you no Grok-specific rule to add to robots.txt.
What did Grok cite in our scans?
Our scans cover the questions Cituna tracks about AI visibility software: 33 scans in the 30 days to 22 September 2026 (how we count). Grok gave 552 answers containing 2,481 citations to third-party sites, about 4.5 per answer. It drew on 125 different third-party sites, not counting the vendors Cituna tracks as competitors; only Google AI Mode, with far fewer answers, drew on fewer.
Its five most-cited sites all sell AI visibility or AI search software, according to their own homepages: rankability.com (75 citations), menra.ai (67), cognizo.ai (59), xseek.io (54) and ayzeo.com (52). Four of the five appear in no other engine's top five in our scans. ChatGPT's top five and Grok's top five have no site in common.
Set aside the vendors Cituna tracks as competitors and the engines' own pages, and look at the 100 third-party sites Grok cited most. Roundups took 77% of their 910 citations and articles 20%. Community sites took 1%: Reddit drew five citations. The site x.com was not among Grok's five most-cited sites.
The mix followed the question:
- How-to questions got how-to articles. For "how to get cited by ChatGPT", the sources included articles on marketerhire.com, contently.com, presspilot.io and searchengineland.com.
- Tool questions got roundups. For "best AI visibility tracking tool", the sources included lists on shadow.inc, lilbigthings.com, theguidex.com and metehan.ai.
- Definition questions went to publishers. For "what is the difference between AEO and SEO", Grok cited techradar.com's piece on AEO versus SEO.
- Audit questions reached code. For "AI visibility audit tool", Grok cited GitHub repositories, including an open-source AI visibility audit.
Big publishers that other engines lean on can count for little here. blog.hubspot.com, ChatGPT's most-cited third-party site with 40 citations, drew three from Grok. What Grok cites has the full list.
What does that mean for your site?
Work Grok as its own channel. With four of its top five sites unique to it, whatever gets you into ChatGPT's or Perplexity's sources will not automatically get you into Grok's. Find Grok's roundups and pitch those. How to get your product into "best tools" roundups covers the approach.
Match the page type to the question. In our scans Grok answered how-to questions from how-to articles and tool questions from lists. A step-by-step guide on your site competes for the first kind; being on the right lists competes for the second.
Use X, but do not rely on it. xAI documents X as a source and X says private accounts are not surfaced, so keep your company account public and post specific, plain facts: what you launched, what it costs, what it works with. In our category, though, x.com was not among Grok's five most-cited sites, and roundups and articles took 98% of the citations to its top 100 third-party sites.
No Grok crawler rule is documented. With no crawler or robots.txt token named on the pages cited here, the practical step is to keep important pages publicly reachable, without login walls, and in plain HTML. JavaScript and AI crawlers explains why the HTML matters.
How do you get cited by Grok, step by step?
- Run each of your buyer questions in Grok and record every cited web page and X post.
- Put Grok's sources next to ChatGPT's for the same questions, and mark the sites only Grok uses.
- Pitch the Grok-only roundups that leave you out, with a reason that fits each list.
- For every how-to question in your set, publish a clear step-by-step article under your own name.
- Make sure your company X account is public, and post your key facts as plain statements.
- Check that the pages you want cited load without a login and show their main content in the HTML.
- If you measure through xAI's API, count inline citations separately from the full list of sources Grok encountered.
- Repeat the runs monthly and compare the source lists, so you can see when a new site enters Grok's rotation.
What to do first
- Run your top five questions in Grok and list every source it cites.
- Mark which of those sources appear in no other engine's answers, and pitch the most-cited one.
- Make your company X account public if it is not.
- Publish one how-to article for your most common how-to question.
