AI Search & GEO

AI Search & GEO: get cited by ChatGPT, Gemini, and Perplexity

Search is no longer only ten blue links. Answer engines — Google AI Overviews, ChatGPT Search, Perplexity, Gemini, Claude, and Copilot — retrieve pages, synthesize answers, and cite sources. Generative Engine Optimization (GEO) and Answer Engine Optimization (AEO) are the disciplines that make your content the one they quote.

This hub collects the definitions, tactics, and free tools Get Search Signal uses to measure and improve AI-search visibility.

What is AI search visibility?

AI search visibility is how often and how prominently a brand, page, or claim appears in answers generated by AI systems such as ChatGPT, Google AI Overviews, Perplexity, Gemini, and Claude. It is measured with metrics like citation rate, mention rate, sentiment, and share of voice across tracked prompts.

How do AI search engines choose what to cite?

AI answer engines retrieve from a text index of the open web (for example Bing for ChatGPT, Google for AI Overviews) and then select passages that answer the query directly. Extractable, self-contained passages backed by specific facts and clear entities are cited far more often than vague marketing copy. Structured data, question-shaped headings, and visible sources all improve retrieval and attribution.

What is the difference between SEO, AEO, and GEO?

SEO optimizes a page to rank in a list of links. AEO (Answer Engine Optimization) optimizes a passage to be extracted as the direct answer in snippets, People Also Ask, and voice results. GEO (Generative Engine Optimization) optimizes a brand and its content to be retrieved, mentioned, and cited inside AI-generated answers. The foundations overlap — crawlability, authority, clear writing — but each adds different structure and measurement.

How do I check if ChatGPT or Perplexity mentions my brand?

Run repeatable prompts that your buyers would ask, across engines, and record which brands are mentioned, how they are described, and which URLs are cited. Manual checks work for a handful of prompts; at scale you need a tracker. Use the free tools below for single-page checks, or the Get Search Signal LLM visibility tracker to monitor mentions, citations, and sentiment across six AI engines.

Related questions

Do AI crawlers execute JavaScript?▾
Most retrieval crawlers — GPTBot, ClaudeBot, PerplexityBot, CCBot, Applebot-Extended — do not execute JavaScript. If your definitions, FAQs, or product content only render client-side, AI systems cannot read or cite them. Server-rendered HTML is a prerequisite for AI visibility.
Does llms.txt help with AI visibility?▾
llms.txt is an emerging convention that gives large language models a curated map of your most important pages. Adoption is early and not guaranteed, but it is inexpensive to publish and forces clarity about your site structure and entity.
Can I rank in Google AI Overviews without ranking organically?▾
Occasionally, but AI Overviews draw heavily from pages already in the top results. Strong traditional SEO — indexability, authority, clear structure — remains the most reliable path into AI answers.
How is AI visibility measured over time?▾
Track a fixed set of buyer prompts per engine, record citations and mentions on a schedule, and watch the trend rather than a single snapshot. Get Search Signal tracks mention rate, citation frequency, sentiment, and share of voice across six engines.
