CoreTrustSeal scores 27/100 for AI visibility - how well ChatGPT, Claude, Perplexity and Google AI Overviews can discover, identify and cite the brand.
CoreTrustSeal 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 (57/100) and its weakest is trust (4/100). It benefits from a Wikidata knowledge-graph entry, a global traffic rank of #994,641 (Tranco) and open access for AI crawlers (GPTBot, ClaudeBot, etc.).
