AI search fix
ClaudeBot user-agent: setup and verification
ClaudeBot is the user-agent Anthropic uses when its crawler requests public HTML for Claude search and citation retrieval. Expect entries in server logs, Cloudflare AI Crawl Control, and Microsoft Clarity Bot Activity when LogPush is enabled. It is distinct from Claude-Web, anthropic-ai, and ordinary browser traffic. To support Claude crawl, allow ClaudeBot in robots.txt and ensure WAF rules do not return 403 or bot challenges to that string. Permitting ClaudeBot does not guarantee Claude will cite or recommend your site.
After policy changes, fetch live robots.txt from production and compare with your CMS editor. Combine log monitoring with a technical audit so ClaudeBot Allow rules survive the next plugin or security template update.

Frequently asked questions
Should I allow ClaudeBot and anthropic-ai?
They may serve different flows. Review Anthropic documentation before allowing additional strings.
Does ClaudeBot use llms.txt?
ClaudeBot fetches HTML and standard URLs. Optional /llms.txt may help after crawl works — it is not a substitute for allowing the bot.
Will ClaudeBot traffic show in analytics?
Usually not in browser session tools. Use server or CDN bot dashboards.
