AI SEO tools for getting cited in AI answers

Ranking on Google is no longer the whole job. When someone asks ChatGPT, Gemini, Perplexity, Claude or Google's AI Overviews which product to use, the answer names a few brands and cites a few pages. These are the tools that tell you whether you are among them, and help you get there.

What answer engine optimization is

Answer engine optimization (AEO, also called GEO) is the work of getting your brand named and cited in AI-generated answers. It shares a lot with SEO: many answer engines search the web before they answer, so pages that rank and answer a question clearly are more likely to be drawn on. But it is measured differently.

That is why this page scores two things for each tool: how it measures citation in AI answers, and what it does to improve it. The score below is the AI answer visibility criterion from the main ranking.

    Improves

    Engines
    AI visibility answers metered per answer read; see its pricing page
    Why this score
    Measures AI answers and builds the pages that answer them, but its pricing page does not name the engines it tracks, so it sits in the middle band.

    Improves
    AI prompts over crawled pages can flag thin or unclear content to rewrite.
    Engines
    None tracked; uses model APIs you connect
    Why this score
    No tracking of AI answers; AI is used for page analysis only.

How to use these tools well

  1. Write down the 20–50 questions your buyers actually ask before they choose you, in their words.
  2. Track them on the engines your buyers use, daily if your plan allows; weekly hides too much variation.
  3. For each question where a competitor is named and you are not, read the pages the answer cites.
  4. Publish or fix the page that answers that question better, with facts that can be checked.
  5. Re-measure after the engines have had time to recrawl, and compare the rate, not one answer.
