Glossary
SEO, AEO and GEO, in plain English.
The terms behind getting found on Google and cited by AI — what each one means and why it matters to a business.
- SEO (Search Engine Optimization)
- The work of making a website rank in Google's and Bing's organic results: fast pages, clean structure, crawlable content, the keywords customers actually search, and links from trusted sites.
- AEO (Answer Engine Optimization)
- Structuring content so search engines and voice assistants lift it as the direct answer — featured snippets, People Also Ask, Siri and Alexa. It rewards pages that ask a real question and answer it in the first two sentences.
- GEO (Generative Engine Optimization)
- Making AI assistants — ChatGPT, Perplexity, Gemini, Claude and Google AI Overviews — name and cite a business when a user asks for a recommendation. It depends on clear entity information, structured data, consistent facts across the web, and content an AI can quote.
- Google AI Overviews
- The AI-written summary Google shows above the normal results for many searches. It cites a handful of source pages; being one of them is the new top spot.
- llms.txt
- A plain-text file at the root of a website (/llms.txt) that tells AI models what the site is, what it offers and where the key pages are — a sitemap written for language models instead of crawlers.
- Schema markup (structured data)
- Machine-readable labels, usually JSON-LD, that tell search engines and AI exactly what a page describes — a LocalBusiness, a Service with a price, an FAQ, a review. It is how a site states facts instead of hoping they are inferred.
- Entity
- A distinct, identifiable thing — a business, a person, a place — that search engines and AI models track across the web. Strong entities have the same name, address, phone and description everywhere they appear.
- E-E-A-T
- Experience, Expertise, Authoritativeness and Trustworthiness — the qualities Google's quality guidelines use to judge whether content deserves to rank. Real authors, real credentials and real reviews are how a site shows them.
- Core Web Vitals
- Google's page-experience measurements: how fast the main content loads (LCP), how quickly the page responds to input (INP), and how much the layout jumps around (CLS). Slow sites rank lower and convert worse.
- Featured snippet
- The boxed answer at the top of a Google result page, quoted directly from one website. AEO is largely the practice of winning these.
- AI citation
- A link or source mention inside an AI assistant's answer. Citations are how AI search sends traffic and trust to a business; a site nobody cites is invisible in AI search.
- Google Business Profile
- The free listing that powers a business's presence in Google Maps and the local pack. Complete, accurate profiles with steady reviews are one of the strongest local ranking signals.
- Local pack
- The map and three business listings Google shows for searches with local intent, like 'plumber near me'. Most local calls come from here, not from the organic links below it.
- Canonical URL
- The one official address for a page, declared in its code, so search engines do not split ranking signals between duplicate versions of the same content.
- robots.txt
- A file at a site's root that tells crawlers — including AI crawlers like GPTBot, ClaudeBot and PerplexityBot — which parts of the site they may read. Blocking them by accident removes a business from AI answers.
- AI crawler
- A bot that reads websites for an AI company — GPTBot and OAI-SearchBot (OpenAI), ClaudeBot (Anthropic), PerplexityBot, Google-Extended. Some gather training data; others fetch pages live to answer a user's question and cite them.
- Google AI Mode
- Google's conversational search experience, where the whole answer is generated by AI and cites a set of sources. It rewards the same things AI Overviews do: pages that rank, answer clearly and can be trusted.
- Zero-click search
- A search where the answer appears right on the results page — a featured snippet, map pack or AI Overview — so the user never clicks a link. Being the answer, or the business named in it, matters more than the click.
- People Also Ask
- The expandable boxes of related questions in Google's results, each answered by a quote from one website. A prime AEO target: question-shaped headings with short, direct answers win them.
- NAP consistency
- Keeping your business Name, Address and Phone number identical everywhere they appear — your website, Google Business Profile, Apple Maps, Yelp and directories. Mismatches make search engines and AI less confident you are one real business.
- Backlink
- A link from another website to yours. Relevant links from trusted sites — local chambers, partners, press — remain one of the strongest signals that your business is real and reputable.
- Title tag
- The page title shown as the blue headline in search results and in the browser tab. For a local business it should name the service and the city, in under about 60 characters.
- Google Search Console
- Google's free tool that shows which of your pages are indexed, which searches you appear for, and how many people click. The first place to look when a site isn't showing up.
