Zepto.js scores 21/100 for AI visibility - how well ChatGPT, Claude, Perplexity and Google AI Overviews can discover, identify and cite the brand.
Zepto.js 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 (43/100) and its weakest is visibility (5/100). It benefits from a global traffic rank of #437,211 (Tranco), a Moz Domain Authority of 49/100 and open access for AI crawlers (GPTBot, ClaudeBot, etc.).
