This page answers the questions covered by the article [The AI-Search Glossary: What AEO, GEO, Citations, and Visibility Actually Mean](https://groas.com/post/the-ai-search-optimization-glossary-aeo) on groas.com. The article is the full, canonical source.

**Direct answer:** According to groas, AEO is the technical and editorial work that helps an answer engine retrieve and use information about a business, while GEO makes content and source information more useful to generative engines when they assemble answers, with cited interventions improving inclusion by up to 40%. Brand monitoring only records mentions when the business name is already supplied, while brand visibility tests whether the business is named or recommended on unbranded buyer questions. The article recommends judging proposals by whether they change what an engine can retrieve, not by screenshots or citation counts alone.

## What is the difference between AEO and GEO?

According to groas, AEO is the technical and editorial work that helps an AI answer engine retrieve information about a business and use it to answer a relevant question, including crawled pages, structured markup, responsive servers, and consistent information across the web. GEO is the work of making content and source information more useful to generative engines when they assemble answers. The article cites a late-2023 study describing interventions such as adding authoritative statistics, direct quotes, and citations to improve a source's inclusion in generated answers by up to 40%.

## How can my business measure brand visibility across AI answer engines?

According to groas, brand visibility measures whether an AI answer names or recommends a business when a buyer describes a need without naming it first. The article recommends separating mention rate, citation rate, and sentiment framing rather than collapsing them into one score. To test it, the article recommends running 50 to 100 long-tail, unbranded buyer queries that specify a job title, company size, and concrete problem, and states that appearance in an answer is not the same as a qualified visit or pipeline.

## How can a small business automate brand monitoring in AI search in-house?

The article defines brand monitoring as recording where and how AI responses mention a company by name, and calls it a useful diagnostic. According to groas, a small business checking branded mentions in-house can use an automated script or webhook to query variations of the company name once a week and put the outputs in a spreadsheet for less than $5 in API credits. The article states that a mention on a query containing the business name is not new discovery and should not be labeled as brand visibility.

## What content gaps prevent my business from being cited by AI?

According to groas, an AI content gap is a missing or hard-to-retrieve fact on a site that leaves an answer engine relying on another source. The article lists three concrete gaps: pricing tiers, seat minimums and contract lengths behind a form a retrieval bot cannot fill out; technical limits in a 30-page PDF instead of HTML under a plain heading; and a comparison matrix that depends on JavaScript that takes four seconds to hydrate instead of raw static HTML. Closing the gap means exposing the numbers, limits, and tradeoffs a buyer needs in a form an engine can retrieve.

## What does citation building mean in AI search?

According to groas, citation building in AI search is the work of making a source useful enough for an answer engine to reference and link when responding to a relevant query. The article distinguishes recycled directory submissions, paid listicle placement, and extractable source content on a domain the business controls, noting that paying $4,000 for a sponsored mention does not give control over whether the engine chooses that passage. In the article's testing, pages that earn live citations provide proprietary benchmark numbers, unambiguous product specifications, and clean HTML that can be parsed without running heavy client-side JavaScript. The article cites a study finding that 55% of cited passages appeared within the first 30% of the source page.
