Lumen scores 49/100 for AI visibility - how well ChatGPT, Claude, Perplexity and Google AI Overviews can discover, identify and cite the brand.
Lumen has a limited AI-visibility profile at 49/100 - a proxy for how readily ChatGPT, Perplexity and Google's AI Overviews can recognise and cite it. Its strongest area is recommendation likelihood (69/100) and its weakest is trust (37/100). It benefits from a Wikidata knowledge-graph entry, a global traffic rank of #33,206 (Tranco) and a Moz Domain Authority of 80/100.
