What Do the Terms in AI Search Optimization Mean?
Direct answer
AI search optimization uses a mix of established SEO terms and newer concepts specific to how AI platforms find, understand, and recommend businesses. This glossary defines each term in plain language, with concrete examples, so the rest of the site can link out to a definition instead of re-explaining it inline.
AI Search Visibility
AI search visibility is how easily AI-powered tools such as ChatGPT, Google AI Overviews, Gemini, Claude, and Perplexity can find, understand, and accurately describe or recommend a business when answering a relevant question. It depends on different signals than traditional search rankings, including entity consistency, structured data, and content that directly answers real customer questions.
Answer Engine Optimization (AEO)
Answer Engine Optimization is the practice of structuring website content so that answer engines, AI tools that generate a direct response rather than a list of links, can extract and quote it accurately. It focuses on question-based headings, direct-answer paragraphs, and FAQ content rather than the keyword density and backlink signals traditional SEO relies on.
Generative Engine Optimization (GEO)
Generative Engine Optimization is the practice of making a business understandable and recommendable to generative AI platforms such as ChatGPT, Gemini, and Perplexity by ensuring the business is documented as a consistent, verifiable entity across its own website and the wider web, not just optimized on a single page.
LLM Visibility
LLM visibility refers to whether and how accurately a large language model, the technology behind tools such as ChatGPT, Gemini, and Claude, can represent a business when asked a relevant question, whether the model is answering from its trained knowledge or from a live web search performed as part of generating the response.
AI Citations
An AI citation is a mention or link that an AI tool includes as a source when generating an answer, similar to a footnote. Platforms such as Perplexity, Google AI Overviews, and Bing Copilot display citations directly within their responses; ChatGPT and Claude show them specifically when web search is used to answer a question.
Entity SEO
Entity SEO is the practice of establishing a business as a single, clearly defined, consistently described entity across the web, so that search engines and AI platforms can confidently connect every mention, listing, and review to the same business rather than treating them as unrelated fragments.
Structured Data
Structured data is a standardized code format, most commonly Schema.org markup written in JSON-LD, added to a webpage to explicitly label what its content means, such as identifying a business name, address, service, or FAQ, in a way search engines and AI systems can read directly rather than infer from plain text.
Frequently asked questions
Why does AI search have its own glossary of terms?
Because the discipline borrows some language from traditional SEO but means something different by it, and introduces genuinely new concepts, such as AI citations and entity SEO, that traditional SEO glossaries do not cover.
Are these terms industry standard?
Most, such as structured data and entity SEO, are established terms used across the SEO industry. Newer terms, including AEO and GEO, are still settling into common usage, and we define them the way we apply them in our own work.
