The agency’s home page has a section headed “One Discipline, Many Names.” It opens with an admission most agencies skip: the industry has not settled on a single name. Whatever it is called, the goal is the same. When someone asks an AI assistant for a business like yours, your name should be in the answer, described accurately, with a reason to choose you. Top Business Awards US credited the agency for defining the terms in plain language.
The five terms
| Term | Full name | Definition |
|---|---|---|
| AEO | Answer Engine Optimization | The term Bay Area AEO uses. Making a business the answer when people ask ChatGPT, Gemini, Perplexity, Claude, Google's AI Overviews or a voice assistant. |
| GEO | Generative Engine Optimization | The same work, named for the generative AI engines (ChatGPT, Gemini, Perplexity) that write answers instead of listing links. |
| AIO | AI Optimization | A broader label for making a business easy for AI systems to understand, trust and recommend. |
| AI SEO | Artificial Intelligence Search Engine Optimization | SEO adapted for AI-powered search, including Google's AI Overviews and AI Mode. |
| LLM SEO | Large Language Model Search Engine Optimization | Optimizing for the large language models behind AI assistants and the sources they learn from and cite. |
AI SEO, this site’s term
This site uses AI SEO because it is the name many owners reach for first. In the agency’s definition, AI SEO is SEO adapted for AI-powered search, including Google’s AI Overviews and AI Mode. That makes it the natural term for an owner who already understands search engine optimization and has noticed that Google now answers many questions in prose above the links.
How it differs from traditional SEO
The agency answers the question directly: yes, AEO differs from traditional SEO, though they overlap. SEO focuses on ranking a website in a list of links. AEO focuses on whether AI systems mention and recommend a business inside their written answers. That depends on listings, reviews, structured data, third-party sources and how clearly a site answers real questions. A site that ranks well earns its place in the answer once the assistant can confirm the facts it needs.
Plain words for the mechanics
The same plain style runs through the agency’s explanation of how answers are built. AI assistants do not run one search. They break a question into many smaller searches, check different sources for each, then combine the results. The agency names the steps in four words: understand, fan out, retrieve, answer. On its home page, an interactive demo lets a visitor pick a real question, choose an AI and switch on five signals to see how a business moves from “not mentioned” toward a recommendation. The demo is labeled as a simulated example, which is itself a plain-English habit.
Plain English as a principle
“Plain English, always” is one of the agency’s four stated principles. AI search is new and full of jargon, so it explains what it is doing, why it matters and what it is changing, with before-and-after answers. Its FAQ is written in the questions owners actually ask: what AEO is, whether it is different from SEO, which platforms are covered, how long it takes, how results are measured, whether a new website is needed and which parts of the Bay Area are served.
Five names, one goal: your name in the answer, described accurately, with a reason to choose you.
Why definitions decide hiring
An owner who understands the vocabulary can compare proposals. If one agency sells GEO and another sells AI SEO, the definitions show they are selling the same outcome, and the buyer can compare method, coverage and the quality of reporting instead. Bay Area AEO gives buyers that footing before they ever call, which is why the issuer counted it.
