39 scores 21/100 for AI visibility - how well ChatGPT, Claude, Perplexity and Google AI Overviews can discover, identify and cite the brand.
39 has a weak AI-visibility profile at 21/100 - a proxy for how readily ChatGPT, Perplexity and Google's AI Overviews can recognise and cite it. Its strongest area is recommendation likelihood (37/100) and its weakest is trust (12/100). It benefits from a Wikidata knowledge-graph entry and open access for AI crawlers (GPTBot, ClaudeBot, etc.). The main gaps holding it back: no clear Wikipedia entity to anchor it in LLM training data, a low Moz Domain Authority of 25/100 and thin schema.org structured data. In a live check, Claude could already identify 39 from memory (October 2026) - a sign these signals are paying off.
The score combines seven dimensions - name quality, digital presence, visual identity, messaging clarity, trust foundation, AI discoverability, and brand authority - into a single objective benchmark.
Ranked closest to 39: Zunosaki (63/100), Yang Zhang Lab (63/100), AAMSCO Identification Products (62/100), RRS (62/100).
A step up - brands to learn from: ZT Corporate (71/100), Zorgnet-Icuro (71/100).
Category leader: Booksy (96/100).
