What changed in AI search this fortnight

Issue nine. Every two weeks I read what changed across ChatGPT, Perplexity, Google's AI Overviews and AI Mode, and the models behind them, then turn it into what it means for brands that want to show up when a customer asks an AI for a recommendation. This fortnight the news sat on the measuring side. If your AI visibility report is a bathroom scale, this was the fortnight we learned it can misread in three different ways. Nozzle's Derek Perkins says Google has been injecting bad data into results pages it treats as suspect, and Nozzle's own numbers date the rise to 13 September. Inline links in ChatGPT answers went out without their tracking tag for about a week in October. A new preprint found that the sources the ChatGPT API retrieves recovered less than a quarter of the pages the ChatGPT web app cited. Around that, Google moved links higher in its AI answers, Meta's new terms cover crawling the websites of businesses that use its products, and Google's guidance now calls fabricated author profiles a form of deception. Here is what moved.

TL;DR

  • Nozzle's Derek Perkins describes Google "injecting bad data into suspect SERPs", and Nozzle's own analysis of 27.5 million results pages puts poisoned pages at 8.0 percent since 13 September against 0.17 percent before, with no comment from Google.
  • From about 2 p.m. Pacific on 8 October until a fix rolled out on 15 October, inline links in ChatGPT answers lost their utm_source tag, and Adobe's Cedric Huesler measured attributable ChatGPT visits falling to about a third of normal while direct visits rose.
  • A preprint comparing the ChatGPT web app with the Responses API found the API's sources recovered 22.9 percent of the URLs the app cited for GPT-5.3 Instant, so in our reading a visibility score built on API calls measures something next to the product.
  • Meta's new Commercial Terms, effective 30 October, authorise it to crawl the domains linked to the products or services of anyone who uses Meta products for business, and Meta's Andy Stone says robots.txt still governs its two user agents, Meta-ExternalAgent for training and Meta-WebIndexer for Meta AI search.
  • Google says it will show inline links higher in its AI responses more frequently, and its guidance now calls fabricating creator profiles with AI-generated headshots, made-up names or false credentials a form of deception.
