## What ClaudeBot means

ClaudeBot performs broad crawling. Claude-User handles retrieval initiated when someone asks Claude a question that requires fetching a page. They're separate user agents and can be controlled independently.

Claude's audience skews heavily professional and technical, with concentrated use in software development, research and analysis contexts.

## Why it matters for AI search

Claude tends toward careful, qualified answers. When corroboration is thin it hedges — 'some sources suggest' rather than stating something directly — and a hedged mention persuades far less than a confident recommendation.

That makes crawler access necessary but not sufficient. Being readable gets you considered; being corroborated gets you stated confidently.

## See it in action

Access is the entry ticket. Corroboration decides how confidently you're mentioned.

#### Hedging is a visibility problem in itself.

Being mentioned tentatively is closer to not being mentioned than to being recommended. Corroboration is the lever that changes it, and it's the slowest one.

## How to get it right

### Working with Claude's crawlers

- Verify both ClaudeBot and Claude-User receive full content
- Check bot-management rules separately; they block unfamiliar agents by default
- Prioritise documentation crawlability — Claude's audience skews technical
- Track hedged mentions separately from absent ones; they're different problems
- Build corroboration on specific claims rather than generic brand mentions

## Common questions

Is Claude worth optimizing for given smaller reach?

As an extension of existing AI SEO, usually yes — the marginal cost is near zero because the work is shared with other platforms.

Its audience skews professional and technical, which is often exactly the audience B2B and developer-tool brands want.

Why does Claude hedge about our brand?

Usually thin corroboration. Claude qualifies heavily when facts aren't supported by independent sources.

It's a useful diagnostic — hedging tells you which specific claims lack external verification.

Does Claude search the web?

It can, depending on the surface and how the question is posed. Some answers come from live retrieval with citations, others from existing knowledge.

So both pathways matter: accessible content for retrieval, sustained corroboration for what the model carries.
