Claude does not draw evenly from the web. It skews toward well-established, text-dense sources that were prominent at training time. Claude answers from model weights unless web search is enabled for the conversation. In its default mode there is no live retrieval at all, so what it says about your brand reflects what was in its training data: which is why the fix here is slower and more structural than on the live-retrieval engines.
How Claude actually decides
Claude answers from model weights unless web search is enabled for the conversation. In its default mode there is no live retrieval at all, so what it says about your brand reflects what was in its training data: which is why the fix here is slower and more structural than on the live-retrieval engines.
Its citations skew toward well-established, text-dense sources that were prominent at training time. In practice that means the surfaces worth auditing first are documentation sites, long-form editorial, Wikipedia, technical references.
The method, in order
Start from the skew, not from your site. Claude’s citations concentrate in documentation sites, long-form editorial, Wikipedia, technical references.
Separate the sources it cites from the sources it trusts silently. This engine frequently asserts without linking, so the citation list understates what shaped the answer.
Check your category specifically. Citation skew is a population-level finding; the sources for legal advice and for developer tooling are not the same, and only your own prompt set tells you which applies.
Audit whether you appear on the top sources at all, then rank the gaps by how hard each is to close: a subreddit comment and a Wikipedia citation are not the same amount of work.
Re-measure after each placement lands. Claude’s volatility is low in default mode; high once web search is switched on.
The honest caveat
A brand founded or renamed recently can be absent from Claude entirely while doing well everywhere else, and no amount of on-page work fixes that quickly. It is the clearest example of why a single-engine tool misleads.
Cituna checks Claude daily alongside the other five engines, ChatGPT, Perplexity, Gemini, Claude, Grok and Google AI Overviews, on the $39 Starter, and pairs the result with Google Search Console so a change here can be tied to real clicks. We do not track Microsoft Copilot.
