What Is the Semantic Authority Score and How Is It Measured?

The Semantic Authority Score is a KPI developed by Zeno Visibility that quantifies how strongly a brand is established as a topical authority in AI search systems. It measures citation frequency, recommendation context, and semantic connectivity across all relevant LLMs — ChatGPT, Gemini, Perplexity, Claude, and Copilot. It replaces Domain Authority as the relevant metric for AI Visibility.
