A
AEO (Answer Engine Optimization) Optimizing your website content to appear as the direct answer to a question specifically in Google's "featured snippets," the highlighted answer boxes that sometimes appear at the top of search results. AEO is a subset of SEO and is related to but different from GEO. See also: GEO, SEO.

AI Overviews Google's feature that generates an AI-written answer at the top of many search results, above the traditional list of website links. AI Overviews pulls from multiple sources and synthesizes a response, citing those sources alongside the answer. Getting your website cited as a source in AI Overviews is one of the most valuable visibility outcomes in GEO.

AI Visibility Score A score from 0 to 100 that measures how easy it is for AI tools to find, identify, and confidently recommend your business. Calculated across eight dimensions of your online presence. A score above 65 is considered strong. A score below 30 means AI has very little reliable information about your business.

B
Behind-the-scenes business information Invisible code added to your website that tells AI tools exactly who your business is, what it does, and where it operates in a format machines can read instantly without interpreting your marketing copy. Also called "structured data" or "schema markup" in technical contexts. The plain-language version: a machine-readable business profile built into your website.

C
Citation frequency How often AI tools name your business in their responses to relevant searches. Measured by running a consistent set of test searches monthly and counting how many times your business appears. The most direct measure of AI visibility progress.

Content gap A question your ideal clients are asking AI that your website doesn't currently answer. Each content gap is an opportunity: the business that answers it well gets cited. Identifying and closing content gaps is one of the core ongoing activities in GEO.
Credibility signals The evidence AI uses to evaluate whether a business is real, established, and worth recommending. Includes Google reviews, third-party mentions, published credentials, years in business, and any outside confirmation that the business is legitimate and active.
E
Engine coverage The number of major AI platforms that mention your business. Tracked across six platforms: ChatGPT, Google AI Overviews, Perplexity, Gemini, Grok, and Claude. A business appearing on five or six of these has strong engine coverage. A business appearing on only one has a narrow presence regardless of how strong that one appearance is.
Entity recognition Whether AI can clearly identify your business as a specific, real, distinct thing in the world with a confirmed name, location, service type, and description. When AI recognizes your business as a clear entity, recommendations become more confident. When it can't build a clear picture, it hedges or skips you. See also: entity consistency.

Entity consistency Whether the information about your business is the same across every platform where your business appears. A business with identical name, address, phone number, and description across its website, Google, Yelp, LinkedIn, and directories has strong entity consistency. Inconsistencies reduce how confidently AI can identify and recommend you.
F
FAQ section A section of your website containing questions your clients commonly ask, each answered in a full paragraph. FAQ sections are the highest-impact content format for AI visibility because AI actively looks for question-and-answer content when generating responses. Answers should be specific, complete, and written so they make sense without any surrounding context.
G
GEO (Generative Engine Optimization) The practice of getting AI tools ChatGPT, Gemini, Perplexity, Google AI, and others to recommend your business by name. GEO is different from SEO: SEO gets you found in traditional search results; GEO gets your business named as the answer when someone asks AI for a recommendation. The discipline covers website setup, content strategy, review building, and profile consistency.

K
Knowledge Graph Google's database of real-world entities businesses, people, places, and things that Google has verified and connected to each other. Being in Google's Knowledge Graph means Google has confirmed your business exists and understands its basic attributes. Businesses in the Knowledge Graph tend to have stronger visibility across Google AI Overviews and Gemini.
L
llms.txt A plain text file added to a website at the root level (yourdomain.com/llms.txt) that gives AI language models a direct summary of the business what it does, who it serves, and where to find its most important content. Think of it as a welcome note written specifically for AI visitors. Most business websites don't have one yet.

N
NAP consistency Whether your business Name, Address, and Phone number are identical across every platform where your business appears. NAP inconsistency even small variations like "Street" versus "St." or a different suite number creates conflicting information that reduces AI confidence in recommending you. Plain-language version: making sure all your listings say exactly the same thing.
P
Prompt tracking The practice of monitoring specific AI searches prompts over time to track whether your business appears in the results. A consistent set of monthly test searches, run in incognito mode across multiple AI platforms, is the foundation of a prompt tracking system.
S
SEO (Search Engine Optimization) The practice of getting your website to appear higher in traditional Google search results. SEO focuses on ranking your pages for specific keywords, building links from other websites, and maintaining technical website health. SEO and GEO are related but different: SEO targets the list of blue links; GEO targets AI recommendation engines. See also: GEO, AEO.
T
Topical authority Being recognized as a trusted, comprehensive source on a specific topic across the internet. Businesses with topical authority in their field have published substantial, consistent content on related topics over time, have been cited by other websites, and appear reliably in searches across that topic area. In GEO terms, topical authority means AI treats your business as a go-to source in your category.
Training data The information AI was trained on the vast collection of internet text, websites, publications, and other sources an AI model learned from during its development. A business that appears widely and consistently across the internet is more fully represented in training data, which means AI has a richer, more confident picture of that business.
U
Unbranded citation When AI mentions your business in a response to a search that didn't include your business name. For example, appearing in results for "best accountant in Austin" (unbranded) is more valuable than appearing when someone searches "[your firm name] accountant" (branded). Unbranded citations are where new clients come from.
