HDDScan scores 32/100 for AI visibility - how well ChatGPT, Claude, Perplexity and Google AI Overviews can discover, identify and cite the brand.
HDDScan has a weak AI-visibility profile at 32/100 - a proxy for how readily ChatGPT, Perplexity and Google's AI Overviews can recognise and cite it. Its strongest area is trust (46/100) and its weakest is visibility (20/100). It benefits from a Wikidata knowledge-graph entry, a global traffic rank of #695,828 (Tranco) and a Moz Domain Authority of 57/100. The main gaps holding it back: no clear Wikipedia entity to anchor it in LLM training data and no llms.txt to steer AI to its best pages.
