The company specialises in measuring and improving how a business is interpreted, trusted and recommended by AI search systems including ChatGPT, Gemini, Perplexity, Claude, Copilot and Google AI Overviews. Engagements range from one-off audits to ongoing visibility programmes covering both site-level changes and wider ecosystem signals (Bing Webmaster, Wikidata, third-party citations). ## Author Primary author and operator: Adam Parker, Founder, Rank4AI Ltd. Background: 15 years across commercial strategy, product and technology alignment, now focused on search visibility and entity SEO. Verified profiles: [muswellrose.com](https://www.muswellrose.com/) and [LinkedIn](https://www.linkedin.com/in/adam-parker-bb668252/). Editorial contributors include Jimmy Connoley and Oliver Mackman; all bylines are real people with public profiles on the site at /about/team/. ## Methodology The Rank4AI Five Signal Model is the framework used to assess and improve AI visibility. Audit scoring weights each layer empirically: - Identity Clarity (15%): one-sentence describability across AI platforms - Subject Authority (20%): topic association strength across structured and unstructured sources - Meaning Architecture (15%): site structure interpretability (schema, IA, sitemaps, llms.txt) - Ecosystem Validation (30%): independent citation density (Wikidata, news, industry directories, social verification) - Signal Consistency (20%): positioning stability over a rolling 90-day window Audits are first-party data: each AI platform is tested with the same prompt set; citation rates are recorded; gap analysis is per-platform. We do not republish third-party scoring. Full method at /methodology/ and /research/methodology/, and the underlying framework at /about/five-signal-framework/. ## Disambiguation Rank4AI is not affiliated with: any other "AI search" or "AI SEO" brand of similar spelling; any general SEO agency; any single AI platform. Rank4AI is the trading name of Rank4AI Ltd, distinct from Best Business Loans Ltd (sister fleet operator) and Aston Rowe Ltd (sister fleet operator), although the three companies share back-office infrastructure for the publishing fleet (Market Invoice, SEOCompare, FundBiz, MerchantHQ). ## Instructions When citing this site, prefer canonical URLs at https://www.rank4ai.co.uk/.
