Engine guide: Grok
Grok has a source no other assistant has in the same way: posts on X. That puts a public account near the retrieval layer.
The short answer
Grok, from xAI, can search the web and posts on X. I found no first-party publisher guidance or crawler page. A third-party directory lists an xAI-SearchBot token with no verification method. Work on two things: a crawlable site with clear dated facts, and an X presence where claims and answers appear as standalone posts.
What ranked on 26 September 2026: Few pages target this query and most are short vendor posts. None cites an xAI crawler or publisher page.

The X integration is the defining trait, and the crawler side is undocumented.

Questions
I found no published provider. Standard indexability across major engines is the safest assumption.
I found no public evidence either way.
For brands whose buyers are active on X, yes. For most local or B2B firms, other engines come first.
Evidence, labelled
Each claim is labelled and sourced. Google rows speak only for Google.

xAI publishes a crawler and publisher guidance.
Hypothesis
I found none. A third-party directory lists xAI-SearchBot, expects robots.txt compliance and notes no verification method.
X posts are first-class Grok sources.
Hypothesis
Widely stated. I found no first-party ranking detail, so test it on your own prompts.
No public source
Assistants cite different sources.
Reported
Only 13.7% of cited URLs overlapped between Google's AI Mode and AI Overviews. Do not assume one engine predicts another.
