Cosmo-oil has a weak AI-visibility profile at 27/100 - a proxy for how readily ChatGPT, Perplexity and Google's AI Overviews can recognise and cite it. Its strongest area is recommendation likelihood (40/100) and its weakest is trust (19/100). It benefits from a Wikidata knowledge-graph entry, a Moz Domain Authority of 47/100 and open access for AI crawlers (GPTBot, ClaudeBot, etc.).
