Sigma scores 30/100 for AI visibility - how well ChatGPT, Claude, Perplexity and Google AI Overviews can discover, identify and cite the brand.
Sigma has a weak AI-visibility profile at 30/100 - a proxy for how readily ChatGPT, Perplexity and Google's AI Overviews can recognise and cite it. Its strongest area is recommendation likelihood (42/100) and its weakest is trust (14/100). 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 19/100 and thin schema.org structured data. In a live check (September 2026), Claude could not identify Sigma from memory, confirming the gaps above.
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 Sigma: Side By Side Stuff (74/100), ShopRite (74/100), SingleInterface (74/100), Sk8 Skates (74/100).
A step up - brands to learn from: ZuPreem (81/100), Zulay Kitchen (81/100).
Category leader: DHL (97/100).
