How to Measure Whether AI Search Engines Cite Your Website

The useful part

If your organic clicks are falling, the missing layer may be the answer page that now appears before your link. GEO and AEO measure whether ChatGPT, Perplexity, Gemini, Claude, and AI Overviews cite your site, and whether their answers support or weaken your position. Search visibility now has another layer Traditional SEO asks whether a page can be found, ranked, and clicked.

How it works

• Generative search adds a different question: when a user asks for an answer, does the system select your page as a source?
• Both depend partly on familiar SEO signals such as content quality, authority, structure, and technical accessibility.
• They also depend on how well your claims match the wording and intent of natural-language questions.
• An AI answer can mention your brand without linking to your site, link to a competitor, summarize your offer inaccurately, or omit your page entirely.
• For a founder or marketing leader, the practical issue is not whether the technology is interesting.

What to take from it

A page can also be cited for a feature that is no longer available. GEO, or generative engine optimization, focuses on being selected and represented by AI systems. AEO, or answer engine optimization, focuses on making the answer useful, clear, and easy to reuse.

Example or evidence

• In the ZenRadar survey, the five surfaces were ChatGPT, Perplexity, Claude, Gemini, and AI Overviews.
• They do not behave identically, so one result cannot stand in for all of them.
• For each run, record the query, timestamp, locale, market, full answer, cited URLs, competitor mentions, and important omissions.
• A citation may be positive, neutral, or based on a claim that your own page does not support.
