Last Week in AI Search: September 21

This week in one minute. Paywall or block? Both: Google started paying a handful of publishers for what their pages contribute to AI answers, while El País shut out GPTBot, ClaudeBot and PerplexityBot. Costing traffic? The strongest evidence yet says yes: 40% fewer outbound clicks when an AI Overview shows, in the first randomized experiment, and a 23% click-through loss at the most exposed French sites. Where does AI show up now? In more of Google than last week: an AI Mode button in the results-page search bar, AI-written summaries atop local business panels, a “Dive deeper” overview in Discover, all tests Google hasn’t confirmed, and Search Live on Gemini 3.8. Buy your way in? A slot, yes, and now a conversation: ChatGPT Ads is testing Sponsored Agents, an ad that opens a chat with the advertiser’s own bot instead of a click. Will the courts stop it? Not so far: 143 suits and counting, and the first appeals-court ruling went GitHub Copilot’s way.

The Monday map

Google pilots paying select publishers via Search Console

El País blocks GPTBot, ClaudeBot and PerplexityBot

Study: Google AI Overviews cut publisher clicks nearly 40%

Ahrefs: AI Overviews cut CTR 23% in France

Is AI-crawler access now a paywall rather than a block?

Now: two developments —

  • Google confirmed a separate, early-stage pilot paying select publishers via a Search Console panel when their content contributes significantly to an AI answer — a payment tied to answer contribution rather than crawler access, alongside rather than instead of Cloudflare’s Pay Per Crawl split, where access depends on whether the crawler’s operator pays.
  • El País blocked GPTBot, ClaudeBot and PerplexityBot outright, becoming the second large publisher after Quora to reject the payment split entirely. Separately, Stack Overflow moved Anthropic’s ClaudeBot off Cloudflare’s Pay Per Crawl track onto a flat block while leaving GPTBot and PerplexityBot behind the same Cloudflare challenge as before — the panel’s first capture of a crawler moving from paid to blocked.

The standing answer: On the Cloudflare-proxied publishers the wire tracks, yes for some — access is starting to split by whether the crawler’s operator pays rather than by whether the site allows AI crawling at all.

Evidence: Search Engine Journal · first-party data, Crawler access panel

Still open: Whether the GPTBot block at the four Cloudflare sites is a publisher decision naming OpenAI specifically or a Cloudflare-side default reclassifying GPTBot — the panel logs the HTTP response, not who set it or why.

Are AI answers costing me traffic?

Before: The France picture rested on APIG’s industry-wide alleged search-referral loss (33-38%) against Le Monde’s single-title account of no decline.

Now: two developments —

  • The first randomized field experiment on the question — not an observational estimate — found removing Google’s AI Overview raised outbound clicks per search from 0.37 to 0.62, a nearly 40% reduction when it’s shown; self-reported satisfaction held flat either way, and only 7.1% of clicks on AI Overview-bearing pages came from inside the AI answer itself. It is the strongest methodology in the record so far and lands well above the Wikipedia study’s ~5% estimate, though it measures a different thing (all outbound clicks, not one site’s referrals) over a different window (two weeks in early 2026, desktop only).
  • Ahrefs’ analysis of Google Search Console data across 963 French domains found sites most exposed to AI Overviews lost 23.1% of CTR in the nine days after the July 22 launch, with a 5.7% median CTR loss and 8.8% median click loss overall — independent, site-level evidence of the decline APIG alleged, concentrated in the same service-content categories (health worst-hit) Le Monde’s CEO said carried the damage he does see.

The standing answer: It depends on what you publish, and part of the disagreement is instrumentation.

Evidence: study, Digital Content Next · vendor study, Ahrefs Blog

Caveat: AI Overviews CTR study — vendor-published

Still open: Google holds the only complete dataset and has published no methodology behind “billions of clicks”. Until it does, the engine’s own position is the least checkable one in the record.

Now: four developments —

  • Google’s “Dive deeper” test in Discover — a button that opens an AI-generated topic overview linking to related stories — carries code flags for article cards as well as the video cards Google described, per a developer’s inspection reported by PPC Land; the button did nothing when he pressed it.
  • Google was seen testing an AI Overview label atop local knowledge panels for Google Business Profiles, with a “Show more” that expands into an AI Mode-style chat.
  • An AI Mode button appeared inside the search bar on Google’s results page, not only the homepage, in a test Search Engine Roundtable could replicate for some queries.
  • Search Live, Google’s audio-and-video conversational search mode, now runs on Gemini 3.8 Live, its newest live-dialogue model.

The standing answer: On the results page itself, and increasingly around it.

Evidence: single source, PPC Land · single source, Search Engine Roundtable · single source, Search Engine Roundtable · Search Engine Roundtable

Caveat: single-source — confirmation pending

Still open: Whether the results-page AI Mode button and the local-panel AI Overview treatment ship beyond tests. Google has confirmed neither; each was replicated by one reporter.

Can I buy my way into AI answers?

Now: OpenAI added HubSpot and Shopify as ChatGPT Ads’ first CRM and ecommerce integrations, and began testing Sponsored Agents — a labeled ad format that opens a separate conversation with the advertiser’s own AI agent instead of an outbound click — with select US advertisers. Ads Manager also gained per-platform targeting and reporting (Android, iOS, web, desktop) and 7/14/30-day attribution windows, up from a fixed one day. No pricing or transcript visibility disclosed for Sponsored Agents.

The standing answer: You can buy a slot, but not a citation — they are separate games.

Evidence: PPC Land

Still open: Whether buying an ad affects the odds of being cited at all, in either direction. The 3.63% overlap is a snapshot of co-occurrence, not a test — nobody has run the same queries with and without a live campaign.

Will the courts stop AI engines from using my content?

Before: 137 AI copyright suits were pending nationwide, 24 against OpenAI, per the wikiHow complaint’s Aug. 22 count.

Now: three developments —

  • Anthropic moved to dismiss copyright claims from opt-out plaintiffs in Shakespeare v. Anthropic — a separate case from Cambronne — arguing they are barred by the Copyright Act’s three-year statute of limitations.
  • Times Publishing Company (Tampa Bay Times) sued OpenAI and Microsoft, the second newspaper publisher to do so in under two weeks after the Seattle Times and Newsday’s Sept. 4 suit.
  • The Ninth Circuit affirmed dismissal of the claim that GitHub Copilot stripped copyright-management information — the ownership and licensing tags attached to code — when it generated new code — the first federal circuit ruling on the question — while rejecting the district court’s own “identicality requirement” reasoning as a misnomer.

The standing answer: Not so far.

Evidence: court filing, Chat GPT Is Eating the World · court filing, Chat GPT Is Eating the World · court filing, Chat GPT Is Eating the World

Still open: Whether roughly $3,000 per work becomes a benchmark or stays a one-off. Bartz settled rather than ruled, so it binds nobody — and no other case has produced a number.
