GEO & Digital Marketing Glossary

A reference, link, or mention of a specific source within an AI-generated answer. Earning citations — being named or linked as the source for a fact or recommendation — is the primary success metric for GEO, similar to how rankings are the primary metric for traditional SEO.

Google's AI-generated summary that appears above traditional search results for many queries, synthesising information from multiple sources into a single answer with citations. Appearing in an AI Overview — and being named as a source — is one of the clearest signals that a page is GEO-optimised.

A closely related discipline focused on structuring content so it can be lifted directly as "the answer" by voice assistants, featured snippets, and AI chat interfaces — typically through clear question-and-answer formatting, concise definitions, and structured data. AEO and GEO overlap heavily; AEO is often considered an early predecessor of GEO.

The set of rules that determines how credit for a conversion is assigned across the multiple touchpoints — ads, organic search, AI citations, email — a customer interacts with before converting. Choosing the right attribution model affects which channels appear to be "working" and where budget gets allocated.

A link from another website pointing to yours. Backlinks from relevant, reputable sites act as a trust signal for both traditional search engines and AI systems, indicating that other sources consider your content worth referencing.

The "preferred" version of a page specified in HTML when the same or similar content is accessible via multiple URLs — for example, with and without tracking parameters. Canonical tags prevent duplicate-content confusion and consolidate authority signals onto a single URL.

The percentage of people who click a result after seeing it, calculated as clicks divided by impressions. A low CTR despite strong rankings often signals that a title or description isn't compelling — or that an AI Overview is answering the query before users reach the results.

A pillar page covering a broad topic, supported by a group of related articles that each address a specific sub-topic and link back to the pillar. This interlinked structure is one of the most effective ways to build topical authority — and a strong signal to AI systems that a site comprehensively covers a subject.

The practice of improving the percentage of website visitors who complete a desired action — such as submitting a form or making a purchase — through testing changes to layout, copy, and calls to action. CRO ensures that the extra visibility GEO and SEO generate actually converts into business results.

A server-side tracking method — used by Meta, Google, and others — that sends conversion data directly from a business's server to the ad platform, bypassing browser-based limitations like ad blockers and cookie restrictions. CAPI significantly improves the accuracy of ad attribution.

A set of Google metrics measuring real-world page experience: loading speed (LCP), interactivity (INP), and visual stability (CLS). Strong Core Web Vitals scores support both search rankings and crawlability, since slow or unstable pages are harder for bots to process reliably.

How easily search engine and AI bots can access, read, and index the pages on a website. Issues like broken links, blocked resources, slow load times, or missing sitemaps can prevent otherwise great content from ever being seen — or cited.

Short for Experience, Expertise, Authoritativeness, and Trustworthiness — the framework Google's quality raters and algorithms use to assess content quality, especially for topics affecting health, finances or safety. Strong E-E-A-T signals, such as author bios, credentials, and reviews, help both search rankings and AI citation likelihood.

The practice of structuring content, data and digital signals so AI systems such as ChatGPT, Google AI Overviews, and Perplexity recognise a business as a credible source and cite it directly in generated answers — rather than only ranking it in a list of links. GEO requires specific, verifiable content, structured data, topical authority, and a consistent digital footprint.

Google's current website analytics platform, which tracks visitor behaviour, traffic sources, conversions, and engagement using an event-based data model. GA4 data helps measure whether GEO and SEO efforts are translating into real traffic and leads.

A free Google tool that shows how a website performs in Google Search — including which queries it appears for, click-through rates, indexing issues, and increasingly, AI Overview appearance data. It's an essential diagnostic tool for both SEO and GEO.

When an AI system generates information that sounds plausible but is factually incorrect or fabricated, often because it lacks reliable source material on a topic. Businesses with thin or inconsistent online information are more likely to be misrepresented through hallucination.

The type of AI model (e.g. GPT, Gemini, Claude) that powers chatbots and AI search assistants. LLMs are trained on vast amounts of text and generate responses by predicting the most likely next words — which is why factual accuracy and consistency across the web matter for being represented correctly.

The question or instruction a user types into an AI assistant — for example, "best accountants in Cape Town for small business". Understanding the real prompts your customers use, not just the search keywords they type into Google, is central to GEO content planning.

A technique AI systems use to improve accuracy by retrieving relevant, up-to-date content from external sources — websites, documents, databases — before generating a response, rather than relying only on what the model memorised during training. RAG is why fresh, well-structured content increases citation chances.

Standardised code — typically JSON-LD, based on the schema.org vocabulary — added to a webpage that explicitly tells search engines and AI systems what the content means: this is a FAQ, this is a review, this is a local business with these opening hours. Structured data is one of the highest-leverage GEO investments because it removes ambiguity for machines.

The practice of improving a website's visibility in traditional search engine results pages through technical improvements, content quality, and authority signals like backlinks. SEO remains the foundation that GEO builds on — the two disciplines work best together.

The page displayed after a user runs a search, containing organic listings, ads, AI Overviews, local packs, and other features. Understanding what occupies a SERP for your target queries shows where the real opportunities — including AI Overview placements — actually are.

The degree to which a website is recognised as a comprehensive, trustworthy source on a specific subject, built by publishing depth of interlinked content rather than isolated pages. AI systems favour sources with demonstrated topical authority when selecting what to cite.

A small piece of code placed on a website that records visitor actions — page views, purchases, form submissions — and sends that data back to an advertising platform, enabling retargeting and conversion measurement. Browser privacy changes have made pixel-only tracking less reliable, which is why pairing pixels with server-side tracking (CAPI) is now standard.

Tags added to the end of a URL — for example ?utm_source=newsletter&utm_medium=email — that tell analytics tools exactly where traffic came from. Consistent UTM tagging is essential for accurately attributing leads and revenue to specific campaigns.

A search where the user gets their answer directly from the results page — via an AI Overview, featured snippet, or knowledge panel — without clicking through to any website. Zero-click searches are increasing, which is why being cited as the source matters more than ever, even without a click.
