NDI scores 44/100 for AI visibility - how well ChatGPT, Claude, Perplexity and Google AI Overviews can discover, identify and cite the brand.
NDI has a limited AI-visibility profile at 44/100 - a proxy for how readily ChatGPT, Perplexity and Google's AI Overviews can recognise and cite it. Its strongest area is recommendation likelihood (63/100) and its weakest is visibility (35/100). It benefits from a Wikidata knowledge-graph entry, a global traffic rank of #3,393,368 (Tranco) and a Moz Domain Authority of 42/100. 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. In a live check (October 2026), Claude could not identify NDI from memory, confirming the gaps above.
The score combines seven dimensions - name quality, digital presence, visual identity, messaging clarity, trust foundation, AI discoverability, and brand authority - into a single objective benchmark.
Ranked closest to NDI: National Consumers League (86/100), NBME (86/100), Nemours Children's Health (86/100), Neuralink (86/100).
