Grok is xAI's AI assistant, built into X and available on its own. It can search the web and X, and in our tracking it searches before it recommends.
Centium tracks Grok on every plan, alongside six other models. What follows are trends from our tracking rather than rules, and we will update this page as they shift.
How Grok answers
Grok turns a question into searches of its own, the same query fan-out we measure across every model, and credits the pages it used. Its sources look different from the other models: more shopping and review platforms, fewer forums.
What we're seeing
Retailers and review platforms lead its sources. Across the brands we track, the sites Grok cites most include large retailers like REI and Amazon and review platforms like TripAdvisor and Yelp.
It reads people. In our research on who AI reads, Grok landed on a named author more often than any other model. A recognized writer covering your category is a strong way in.
Forums and video play a small part. Reddit and YouTube show up far less in Grok's answers than in Gemini's, Perplexity's, or Google AI Mode's.
How to show up in Grok
The fundamentals are the same as for any model. With Grok, your listings, your reviews, and the people who write about you do more of the work.
- Look after your retail listings. Complete product pages and real reviews on the retailers you sell through give Grok a source it favors.
- Earn reviews on the platforms it reads. For places and services, Yelp and TripAdvisor are among the sites it cites most.
- Get covered by named experts. Grok credits individual writers more than other models do, so reviews and features from recognized people in your category travel further with it.
- Keep your own pages clear. When Grok does reach your site, plain statements of what you offer and who it is for are what it can repeat.
- Assume it can read what the public can. Grok has been reported to ignore robots.txt, so a blocking rule is no guarantee. Check your robots.txt for the crawlers that do follow it.
