AI shortlist prompts expose brand visibility gap, NeuroRank finds

Artificial intelligence platforms may give brands a stronger impression of visibility when the brand name is already present in the prompt. NeuroRank’s AI Visibility Index 2026, which analysed 7,580 prompts across ChatGPT, Gemini, Claude and Perplexity, finds a substantial gap between brand recognition and discovery. The study covered 122 brands across nine sectors and found that High inclusion was 56.2% for brand-named results, compared with 17.8% for results where the brand was not named.
