New pages.
- How to track AI visibility is now a method guide: the free monthly routine with Search Console, Bing Webmaster Tools, GA4 and a prompt sheet, and when a paid tool is worth it. It used to repeat the reviews hub, which is where the scored tool picks now live.
- How to track ChatGPT traffic in GA4, step by step, including GA4's new AI Assistant channel and the October 2026 ChatGPT tracking gap.
- AI Overviews vs AI Mode: what's different, what the click and local-results studies show, and what to do about each.
- llms.txt generator and validator, a free tool that runs in your browser.
Corrections.
- Profound engine count: the reviews table showed "3" (the free trial's engines) while our review says up to nine. Tables now show both: "3 on trial · up to 9". Every engine count on the site now comes from one dataset.
- Otterly.AI and Ahrefs prices quoted in our reviews (Otterly's engine and prompt add-ons, Ahrefs' core plans) were rechecked on the vendors' pricing pages and are unchanged.
November 1, 2026
New: reviews and head-to-heads. We added a comparison and review layer built on one product dataset, so every price is the same wherever it appears.
- Reviews hub with a sortable table of eight tools and what 20 tracked prompts really costs on each.
- Reviews of Otterly.AI, Peec AI, Scrunch, Profound, Semrush's AI Visibility Toolkit, Ahrefs Brand Radar and cite-met (ours, not scored).
- Head-to-heads: Otterly vs Peec AI, Profound vs Peec AI, Profound vs Scrunch and Semrush vs Ahrefs Brand Radar, on a new Compare hub.
- How ChatGPT, Perplexity, Google AI, Copilot and Claude choose their sources.
- Methodology with the review rubric, and an author page.
Rechecked prices (November 1). All tool prices were rechecked on the vendors' pages.
- Ahrefs Brand Radar: corrected on the tools comparison. Ahrefs' help centre lists $199 a month per AI platform index and $699 for all platforms; we previously showed only "from $199" and said platforms weren't itemised.
- Profound: its pricing page still lists only a free trial and custom Enterprise pricing.
- AthenaHQ: added to the dataset (free Essential plan; Starter $295).
- Otterly.AI, Peec AI, Scrunch, Semrush and cite-met prices were unchanged.
Updated: Does llms.txt matter?. Added a disclosure: the Observatory data it discusses comes from cite-met, which we own.
Updated: website platforms by AI-readiness. Added a section on default AI-crawler blocking: Cloudflare's new defaults from September 15, 2026, Squarespace's AI crawler toggle, and Wix's robots.txt guidance.
October 31, 2026
Launch. First edition of the AI Search Observatory (Q4 2026, 12 sites), the AI crawler registry, the free AI access checker, and guides to robots.txt for AI crawlers, llms.txt and how AI assistants recommend businesses.
