TL;DR - ClaudeBot is Anthropic's training-data crawler - the user-agent that gathers web content to update future Claude model versions. Distinct from Claude-Web (live retrieval at answer time) and Claude-User (in-session fetches from Projects, pasted URLs, or Computer Use).
ClaudeBot in practice
Decide what ClaudeBot can see, on purpose
ClaudeBot is one of the crawlers Anthropic uses to read the web. Whether it can reach your pages decides whether your store can show up in Anthropic's answers. We write robots rules that let the right crawlers into your product and content pages and keep private areas closed.
- ›ClaudeBot and its sibling crawlers allowed by name
- ›Product and content pages open to crawl
- ›Checkout, cart and account kept private
Definition & scope
ClaudeBotis Anthropic's training-data crawler. It feeds the dataset future Claude model versions are trained on. Allowing ClaudeBot in robots.txt is what makes your content available for that training; what ClaudeBot saw during the last refresh shapes how Claude can describe your brand from memory (the “web search off” answers).
ClaudeBot is one of three Anthropic user-agents. The others: Claude-Web (live retrieval fetched at answer time when Claude needs current web grounding) and Claude-User (user-initiated fetches - fires when a user pastes a URL into Claude.ai, attaches a doc to a Project, or runs Computer Use on a page). All three need explicit allow rules. Full Claude-specific work on /claude-ai-seo-services.
Where you'll encounter it
You'll see ClaudeBot in robots.txt files, server access logs, and CDN bot-management dashboards. Anthropic surfaces its user-agent documentation on the company site; check the canonical strings before configuring rules.
For B2B and technical/research-heavy brands - where Claude is increasingly the default for long-context analysis - ClaudeBot access is the foundation that makes “known-brand” citations possible inside Claude.ai answers. Web-search-on Claude can still cite live via Claude-Web, but the “from memory” answers depend on training-data access.

FAQ
What is the ClaudeBot user-agent string?
The string includes ClaudeBot as the identifier. Anthropic publishes documentation at anthropic.com - verify the canonical UA list there before configuring robots.txt rules.
Is ClaudeBot the only Anthropic crawler?
No. Anthropic runs three user-agents: ClaudeBot (training data), Claude-Web (live retrieval when Claude needs current grounding), and Claude-User (fetches initiated when a user pastes a URL into Claude.ai, attaches a doc to a Project, or runs Claude Computer Use against a page). All three need explicit allow rules.
Should I allow ClaudeBot in robots.txt?
For most brands, yes. Allowing ClaudeBot makes your content available for inclusion in training-data runs, which shapes how Claude can describe your brand from memory (the “web search off” answers). Disallowing it forfeits memory-resident citations without preventing live-retrieval Claude-Web fetches.
Does ClaudeBot respect robots.txt?
Yes. Anthropic honors robots.txt directives for all three user-agents. Verify hits in your server access logs by user-agent string.
How is ClaudeBot different from Claude Computer Use?
Claude Computer Use is a separate Anthropic product where Claude controls a browser (clicks, scrolls, types) to complete tasks on the user's behalf. Fetches initiated by Computer Use show up as Claude-User, not ClaudeBot. Allowing ClaudeBot trains the model; allowing Claude-User lets Computer Use complete agentic flows against your site.
Does allowing ClaudeBot affect Google ranking?
No. Anthropic and Google run independent crawlers; allow rules for one don't affect the other.
