# Semrush Releases 2026 AI Visibility Index, Revealing Its First UK Benchmark Semrush’s [2026 AI Visibility Index]() adds its first UK benchmark and a comparison with the US. Semrush finds that the brands AI platforms mention and the sources they cite vary significantly between the markets. Visibility on one platform doesn’t guarantee visibility on another. The research covers January to July 2026, using fixed monthly sets of 2.5 million UK prompts and 25 million US prompts across ChatGPT, Gemini, and Google AI Mode. It also includes a larger, variable dataset of Google AI Overviews results for real search keywords.
