Grok has a reputation for pulling from X and talking with confidence, so it's easy to write it off as a citation channel. That's out of date. Grok now combines live web search with X and shows inline citations you can click. The real catch is different: xAI doesn't publish a documented crawler the way OpenAI and Anthropic do, which makes verifying Grok's footprint harder. That's exactly where evidence beats assumption.
Grok answers by combining its model with real-time retrieval from the open web and from X, and presents citations that link out to the sources behind an answer. Because much of its edge is recency, fresh and clearly written pages tend to travel best. Standard, openly crawlable HTML is what any retrieval step can read.
When you can't verify the visitor, you verify the result instead: track whether Grok actually cites you, rather than trusting a crawler claim you can't check.
You can put your audience's questions to Grok and watch for your name, but its answers swing between sessions and lean on whatever's fresh, so a single look isn't evidence, and with no documented crawler to confirm a visit, the citation itself is the signal that counts. Unsourced is built unlike tools that fire a generic prompt list and hope. We construct the test questions from your own footprint: the queries you already rank for in Google and Bing Search Console, the topics you publish on, and the pages real visitors land on, written the way someone would actually ask. We run them on a schedule, record each time Grok cites your domain and which competitors it picks instead, and, where Origin Signal can, show whether a mention came from a live pull or older data. Measurement grounded in your real demand, not a canned list.
Nobody can guarantee a Grok citation, and with limited crawler verification, anyone who promises one is guessing twice over. What you can do is stay openly crawlable, publish fresh answers worth citing, and measure the result honestly, which is the whole point of Unsourced.
Does Grok cite its sources?
Yes. Grok now combines live web and X search and shows inline citations that link to the sources behind an answer, so it can cite your site directly.
Can I verify Grok crawling my site?
Not reliably. xAI does not publish a documented crawler with verifiable IP ranges and reverse DNS, so a “Grok” user-agent should be treated as an unverified claim. Tracking the citation outcome is the more dependable signal.
How do I check whether Grok cites my site?
Unsourced tests the queries you rank for and records when Grok cites your domain, which is the most reliable measure given the limited crawler-level verification.
Unsourced tests the queries you already rank for, records who gets cited, and shows whether each mention came from a live crawl or training data.
