AI SEO Glossary
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).
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.
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.
The string includes ClaudeBot as the identifier. Anthropic publishes documentation at anthropic.com — verify the canonical UA list there before configuring robots.txt rules.
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.
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.
Yes. Anthropic honors robots.txt directives for all three user-agents. Verify hits in your server access logs by user-agent string.
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.
No. Anthropic and Google run independent crawlers; allow rules for one don't affect the other.
