AI visibility

JSONPlaceholder scores 17/100 for AI visibility - how well ChatGPT, Claude, Perplexity and Google AI Overviews can discover, identify and cite the brand.

JSONPlaceholder has a weak AI-visibility profile at 17/100 - a proxy for how readily ChatGPT, Perplexity and Google's AI Overviews can recognise and cite it. Its strongest area is recommendation likelihood (45/100) and its weakest is visibility (0/100). It benefits from a Moz Domain Authority of 51/100 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, no strong Wikidata entry and thin schema.org structured data. In a live check, Claude could already identify JSONPlaceholder from memory (September 2026) - a sign these signals are paying off.
