Per-vendor citation rates are not published because vendors do not document AI citation behaviour as a per-vertical contract. The vertical framework is operator-runnable; per-site observations require a Sentinel snapshot.","claims":[{"id":"claim-comparison-pages-cited-most","statement":"Comparison pages (X vs Y, alternatives to Z) are the most consistently cited UK SaaS surface across ChatGPT Search, Perplexity, and Gemini AI Overviews on commercial-intent queries. Citation rate is driven by clean structured comparison content and entity disambiguation, not by vertical preference.","evidenceUrl":"https://promagen.com/sentinel/weekly","lastVerified":"2026-05-10","hash":"sha256:8a489bd44aee38bfad393dc6920c6d2ca68cd48f1f9099378018de256ae67870"},{"id":"claim-uk-tld-disambiguates","statement":"A .co.uk or .uk top-level domain is one of several entity-disambiguation signals AI engines use to identify a UK-anchored SaaS site. Sites on .com serving UK content from /uk/ require stronger schema-based disambiguation (en-GB inLanguage, hreflang, country-explicit Organization schema) to achieve equivalent citation clarity. Neither path is intrinsically better; the disambiguation work is just different.","evidenceUrl":"https://promagen.com/sentinel/weekly","lastVerified":"2026-05-10","hash":"sha256:bf8d3df3eec7b236d8b6514c90f046900abad6aa98329fe33c1261180d9b78c7"},{"id":"claim-sterling-pricing-must-be-rendered","statement":"AI engines extract pricing from rendered HTML. UK SaaS pricing pages that show sterling values directly in the rendered HTML are more disambiguatable for UK queries than pages that show client-side currency-switched values, because client-side currency switching can hide the rendered sterling value from the engine's parser.","evidenceUrl":"https://promagen.com/sentinel/weekly","lastVerified":"2026-05-10","hash":"sha256:1053fe40523fca7ab0074621bdb3bbaaed8abf12482d8e5ec96ceb3e2d8b96c7"},{"id":"claim-no-vendor-publishes-vertical-citation","statement":"None of the four major AI engines publishes a per-vertical citation behaviour contract. Specific claims like \"ChatGPT prefers UK SaaS sites with X\" or \"Perplexity cites UK SaaS at rate Y\" are inference from observable output, not vendor contract. The honest per-vertical view is observational, not authoritative.","evidenceUrl":"https://platform.openai.com/docs/bots","lastVerified":"2026-05-10","hash":"sha256:11b07d0c6a8dbff74c1f583ee6aebdd7246bf6997d7c93278575e60c6bf009b2"},{"id":"claim-citation-not-search-rank","statement":"AI engine citation rate and Google Search rank are different products with different selection criteria. UK SaaS sites that rank well in Google for commercial queries do not automatically get cited by ChatGPT or Perplexity for the same queries. The structural signals overlap (reachability, content depth, schema clarity, freshness) but the systems weight them differently.","evidenceUrl":"https://promagen.com/sentinel/weekly","lastVerified":"2026-05-10","hash":"sha256:4cdb153c4a06d9da7593a72dbcfb8a588da9ee7ae88da45e9e4d984586590fe1"}]}
