Claude Is The Fastest-Growing AI Traffic Source, Per New Data

Claude despatched virtually 4 occasions extra referral site visitors to web sites in April than in January, per new SE Ranking data.

That made it the fastest-growing AI site visitors supply among the many 5 platforms tracked. It’s nonetheless the smallest by a large margin, and it in all probability isn’t a significant line in your analytics but.

For transparency, SE Rating sells AI visibility monitoring instruments. The figures come from its personal Google Analytics dataset.

What The Information Exhibits

Claude’s share of site visitors in SE Rating’s dataset grew from 0.0029% in January to 0.0141% in April, a 386% improve.

Most of that got here in March, when Claude’s share went from 0.0049% to 0.0127%. SE Rating says that’s the most important single-month soar in Claude’s historical past throughout its dataset.

AI platforms mixed accounted for 0.33% of site visitors as of April, up from 0.1976% a yr earlier. Inside that, ChatGPT generated 78.23% of AI-referred site visitors throughout the total 16-month interval. Perplexity follows at 9.33%, Gemini at 6.85%, and Copilot at 3.57%. Claude accounts for 1.40%.

Between January and April, ChatGPT’s referral site visitors grew 1.53% whereas Gemini grew 63%. The identical dataset confirmed Gemini passing Perplexity earlier this yr.

How SE Rating Explains The March Soar

SE Rating ties the March improve to public consideration on Anthropic in February. Anthropic stated publicly it wouldn’t permit Claude for use for mass surveillance of People or absolutely autonomous weapons. The assertion got here throughout a dispute with the Pentagon over Claude’s utilization restrictions.

The report factors to outdoors figures that transfer in the identical path. It cites Similarweb information exhibiting that Claude reached 11.3 million each day energetic customers on cell in early March. Ramp’s AI Index, based mostly on company spend information, reported Anthropic adoption at 34.4% of companies in its information, in contrast with 32.3% for OpenAI.

The Report Doesn’t Point out OpenClaw

One factor lacking from SE Rating’s evaluation is OpenClaw, the open-source agent framework that runs on Claude fashions.

OpenClaw was one of many greatest Claude-related tales of the identical window. It launched in November and hit 247,000 GitHub stars by early March. Observers called it the fastest-growing mission in GitHub’s historical past. Anthropic restricted subscription access for third-party harnesses, beginning with OpenClaw, on April 4.

That’s extra context somewhat than an evidence for the referral numbers. Agent exercise doesn’t present up as clicks from claude.ai to web sites, so OpenClaw utilization wouldn’t register on this dataset. It’s another kind of Claude exercise that referral reviews can’t see.

The US Is About Ten Months Forward

The expansion sample seems comparable throughout areas within the dataset, however the US leads on each scale and timing.

In April, Claude accounted for 0.0186% of US web site site visitors within the dataset. The EU determine was 0.0100%, and the UK was at 0.0054%.

US web sites reached a Claude site visitors share of 0.0022% in April 2025. Different areas didn’t hit an identical degree till early 2026, roughly ten months later.

Why This Issues

The proportion improve makes the expansion seem bigger than the site visitors behind it. A near-4x improve nonetheless leaves Claude with a small fraction of referral site visitors. The numbers function an early sign to observe, not one thing to react to only but.

SE Rating notes that its information captures solely direct clicks from AI platforms, and that Claude is used primarily for writing, coding, and evaluation, not search.

Wanting Forward

The subsequent month-to-month updates will present whether or not Claude’s March soar was a brand new baseline or a spike. If it holds, websites with US audiences will doubtless really feel any change first. Positions have already moved this yr, with Gemini passing Perplexity in the identical dataset.
