of total AI traffic on a typical SMB site comes from Claude (Attrifast 200-site benchmark) — small in volume, but the highest RPV per visit on B2B SaaS, where Claude reaches $1.94 vs the $1.18 cohort blend.
Why Claude traffic is different
Claude is structurally different from ChatGPT and Gemini: trained with Constitutional AI, positioned around safe and accurate reasoning, distributed primarily through the API to developers and engineering-led teams. The resulting visitor profile is heavily skewed toward technical decision-makers and B2B buyers.
That means Claude traffic is small in absolute volume but disproportionately valuable. Across Attrifast-tracked B2B SaaS sites, RPV from Claude is consistently among the highest of any AI channel — sometimes 2-3x higher than RPV from ChatGPT, even though Claude sends 1/5th the visits.
GA4 has no built-in classification for Claude traffic. Every Claude visit becomes a Direct visit, and the high-quality B2B signal evaporates. Attrifast was built so engineering-led teams selling to other engineering-led teams stop losing that signal.

Claude carries only ~6% of AI session volume, but on B2B SaaS its Revenue Per Visitor tops every engine at $1.94 — a vertical-specific outlier invisible to any aggregated benchmark. See the full per-engine revenue breakdown.
How do you track Claude traffic?
Anthropic sends visitors via the claude.ai referrer and a small set of disambiguating signals. Attrifast records the source when one of those identifying signals is present and keeps crawler requests separate from human sessions.

Claude traffic tracking FAQ
Common questions about detecting Claude referrals, attributing revenue, and what to expect.
How do I track Claude AI traffic to my website?
Claude sends claude.ai as the HTTP Referer header on most outbound clicks. The manual method: capture document.referrer at page load, check for "claude.ai", and store the value server-side with your session so you can join it to payment events. The automatic method: install Attrifast — Claude traffic appears as its own revenue row in the dashboard immediately, with referrer and user-agent signals combined and Stripe payments tied in automatically.
How does Attrifast detect Claude traffic?
Claude passes claude.ai as the HTTP referrer for visits originating from chat, and ClaudeBot as the user-agent when Anthropic fetches pages for citation. Attrifast combines both signals to attribute visits cleanly.
Is Claude traffic large enough to matter?
For most SMB sites, Claude traffic is 3-10% of ChatGPT traffic — small but disproportionately B2B and developer-skewed. If your product targets developers, technical buyers, or enterprise users, Claude is likely your highest-converting AI channel per visit. Attrifast surfaces it as a first-class row so the small-but-valuable signal does not get lost.
Why does Claude traffic skew B2B and developer?
Anthropic's product positioning, Constitutional AI training, and direct API distribution make Claude the AI assistant of choice for engineering teams and technical knowledge work. Visitors who arrive from Claude tend to be evaluators, technical decision-makers, or developers — different audience profile from ChatGPT or Gemini referrals.
Does Claude.ai send the referrer header reliably?
For most desktop and web sessions, yes. Some Claude integrations (Slack, browser extensions) may strip the referrer; Attrifast falls back to user-agent fingerprinting and tags those visits as "Claude-likely".
What about traffic from Claude's API used in third-party apps?
Traffic originating from third-party tools built on the Anthropic API (Cursor, Continue, custom agents) is not natively detectable as Claude traffic — those tools control their own user-agents and referrers. Attrifast detects the most common ones (Cursor, Perplexity, etc.) as separate AI engine sources where possible.
Will ClaudeBot crawls show up as visits?
No. Attrifast filters ClaudeBot from human visit and revenue reports by default. ClaudeBot crawl frequency is available in the AI crawler report when you want it — a useful proxy for how often your content is being indexed for Claude's future answers.
How does Claude traffic typically convert vs ChatGPT?
On Attrifast-tracked B2B SaaS sites, Claude RPV is often higher per visit than ChatGPT — fewer visitors, but each one is closer to a buying decision. On e-commerce sites the gap narrows. Attrifast lets you compare side by side.
Attrifast is a privacy-first revenue attribution tool that ties every visit — including ChatGPT, Perplexity, Claude, and Gemini referrals — to Stripe revenue, so you see which channels earn money, not just traffic.
