Keyword Research Tools for AEO in LLMs: The Real Stack for 2026
The best keyword research tools for AEO in LLMs aren't the ones that report search volume — they're the ones that surface the conversational questions people actually ask ChatGPT, Perplexity, and Google AI Overviews, and then show you whether an AI engine cites you when someone asks. In practice that means a small stack: a question-mapping tool like AlsoAsked or AnswerThePublic to find how buyers phrase things, an AI-visibility tracker like LLMrefs, Peec AI, or Otterly to see if you're being named, and Google Search Console to validate real demand on your own pages.
