How We Built a Content Optimization Tool for AI Search [Study]

A Semrush study examined over 300,000 URLs to pinpoint which text‑only attributes drive citations in AI‑powered search tools such as ChatGPT, Google AI Mode, and Perplexity. The analysis revealed five content qualities—clarity, E‑E‑A‑T signals, Q&A formatting, section structure, and structured data—that each added 22‑33% more AI citations, while a promotional tone cut citation rates by roughly 26%. The research informed the creation of a Content Toolkit that audits pages for these signals, helping marketers boost AI visibility. The findings contrast with traditional SEO metrics, highlighting a distinct set of criteria for LLM citation behavior.
