A

AI Citation Tracking

#ai-citation-tracking
GEO AI & LLMs Analytics
Definition

Monitoring when AI platforms cite, mention, or recommend a brand, page, product, or competitor for target prompts.

Why it matters

It turns GEO from guesswork into measurement by showing which answers include the brand and which sources get credited.

AI Crawl Readiness

#ai-crawl-readiness
Technical GEO
Definition

The state of a site being easy for AI crawlers and search crawlers to access, render, parse, and trust.

Why it matters

It is the technical foundation behind AI citations; if engines cannot crawl or understand the page, they cannot recommend it.

AI Overviews

#ai-overviews
AI & LLMs SEO
Definition

Google's generative answer summaries that appear above the traditional blue links, synthesizing multiple sources into a single response with inline citations.

Why it matters

Appearing as a cited source inside an AI Overview can drive more visibility than ranking first in the links beneath it.

AI Visibility Score

#ai-visibility-score
GEO Analytics
Definition

A composite benchmark for how visible a brand is across AI answers, citations, entity signals, and crawl readiness.

Why it matters

It gives teams a starting point for prioritizing fixes and tracking whether AI visibility is improving over time.

Answer Engine Optimization (AEO)

#answer-engine-optimization
AEO GEO
Definition

The practice of structuring content so answer engines — ChatGPT, Perplexity, Google AI Overviews — can extract a direct, citable answer rather than just a ranked link. The goal is to be the answer, not only to appear in a list of results.

Why it matters

As more queries are resolved with a synthesized answer, AEO decides whether your brand is the source that gets quoted.

Answer-First Content

#answer-first-content
AEO Content
Definition

Content that leads with a clear, self-contained answer before adding detail, examples, or supporting context.

Why it matters

It matches how snippets and AI answers extract passages, increasing the chance your wording becomes the cited response.

B

Brand Entity

#brand-entity
SEO AI & LLMs Authority
Definition

The machine-readable identity of a brand as a distinct entity with names, services, locations, profiles, and relationships.

Why it matters

Clear brand entities help search engines and AI systems connect mentions, reviews, links, and service pages to the same business.

C

Citation

#citation
GEO AI & LLMs
Definition

A reference an AI engine makes to a source when generating an answer, often shown as a linked footnote. Citations are how generative results attribute and credit information.

Why it matters

Earning citations is the central win condition of GEO — being named in the answer is the new equivalent of the top organic position.

Conversion Rate Optimization (CRO)

#conversion-rate-optimization
CRO
Definition

The practice of increasing the percentage of visitors who take a desired action through analysis, testing, and UX improvements.

Why it matters

CRO turns earned and paid traffic into leads, sales, and measurable business outcomes.

E

E-E-A-T

#e-e-a-t
Authority
Definition

Google's quality framework — Experience, Expertise, Authoritativeness, and Trustworthiness — used to assess whether content and its creator are credible.

Why it matters

Strong E-E-A-T signals make a brand more likely to be surfaced and cited by AI engines that weight source trust heavily.

F
G

Generative Engine Optimization (GEO)

#generative-engine-optimization
GEO
Definition

The discipline of optimizing content and entities to be surfaced, synthesized, and cited by generative AI engines such as ChatGPT, Gemini, and Perplexity.

Why it matters

As discovery shifts from links to AI-generated answers, GEO is how brands stay visible in the systems that increasingly mediate that discovery.

Google Business Profile

#google-business-profile
Local Reputation
Definition

A business listing in Google that powers local results, maps information, reviews, photos, hours, and calls.

Why it matters

An accurate and active profile is one of the strongest foundations for local visibility and local AI recommendations.

K

Knowledge Graph

#knowledge-graph
SEO AI & LLMs
Definition

Google's database of entities and the relationships between them, used to understand meaning and power rich, fact-based results.

Why it matters

Connecting your entities to the Knowledge Graph — via schema and sameAs references — strengthens how reliably engines recognize your brand.

L

Large Language Model (LLM)

#large-language-model
AI & LLMs
Definition

An AI model trained on vast amounts of text to understand and generate human-like language — the technology behind ChatGPT, Gemini, and Perplexity.

Why it matters

LLMs are the new intermediaries of discovery; understanding how they retrieve and cite content is the foundation of GEO and AEO.

O

Online Reputation Management

#online-reputation-management
Reputation Authority
Definition

The practice of monitoring, improving, and protecting how a brand appears across reviews, search results, social channels, and AI answers.

Why it matters

Reputation signals influence whether users trust a brand and whether engines feel confident recommending it.

P

Pay-Per-Click (PPC)

#pay-per-click
Paid Search
Definition

A paid advertising model where advertisers pay when someone clicks their ad.

Why it matters

PPC can generate immediate demand capture when campaigns, landing pages, and tracking are managed tightly.

Product Schema

#product-schema
eCommerce Technical
Definition

Structured data that describes a product, including name, image, brand, offers, availability, price, and reviews.

Why it matters

Product schema helps search engines and AI systems understand exactly what is being sold.

R

Retrieval-Augmented Generation (RAG)

#retrieval-augmented-generation
AI & LLMs
Definition

An AI architecture that retrieves relevant external documents at query time and feeds them to a model so its answer is grounded in current, specific sources.

Why it matters

RAG is why crawlable, well-structured content matters for AI visibility — your pages can be retrieved and cited even if the model never trained on them.

S

Schema Markup

#schema-markup
Technical
Definition

A standardized vocabulary (schema.org) added to a page's code that helps search engines and AI understand the meaning and relationships of its content.

Why it matters

Schema is the connective tissue of entity SEO — it turns plain content into explicit, machine-readable facts engines can trust and reuse.

Structured Data

#structured-data
Technical
Definition

Information organized in a standardized format — usually schema.org as JSON-LD — that explicitly describes a page's content to machines.

Why it matters

It's the foundation that makes single-page glossaries viable — DefinedTerm structured data keeps every term a distinct entity at one URL.

V

VideoObject Schema

#videoobject-schema
Video Technical
Definition

Structured data that describes a video, including its name, description, thumbnail, upload date, duration, and embed URL.

Why it matters

VideoObject schema helps engines understand and feature video content in rich results and AI surfaces.

Z
