Answer Engine Optimization. An earlier term sometimes used to describe optimizing for AI and voice search. GEO is the more comprehensive and current term.
AI that can take actions on behalf of users, not just provide information. Includes booking, purchasing, and completing tasks. The future of AI where brands AI trusts will be brands AI buys from.
AI making purchase decisions and transactions on behalf of users. Being developed by Google, OpenAI, and Microsoft. Will make AI recommendations even more valuable.
An AI system designed to help users with tasks, answer questions, and provide recommendations. ChatGPT, Claude, Gemini, and Copilot are AI assistants.
A bot that visits websites to gather content for AI systems. Examples include GPTBot (OpenAI), ClaudeBot (Anthropic), and PerplexityBot. These crawlers collect data for training and/or real-time search.
Google's AI-generated summaries that appear at the top of search results for many queries. Blends traditional SEO with GEO — your content can be cited in these AI summaries.
The use of AI assistants like ChatGPT, Claude, or Perplexity to find information, get recommendations, and answer questions — as an alternative or complement to traditional search engines like Google.
A general term for optimizing for AI search systems. GEO is the more specific and widely-used term in the industry.
How often and how favorably your brand appears in AI-generated responses. The core goal of GEO — being mentioned, recommended, and accurately represented by AI systems.
Building your brand's entity and authority so AI recognizes, trusts, and recommends it. Includes entity optimization, knowledge graph presence, and reputation management.
Instances where AI includes your brand name in its responses. Tracking brand mentions across AI platforms is a key GEO metric.
OpenAI's AI assistant, the largest and most widely-used AI chat platform. Over 200 million weekly active users. A primary target for GEO optimization.
When AI explicitly references a source for its information. Perplexity always shows citations; other AI varies. Being cited builds credibility and drives traffic.
Anthropic's AI assistant, known for nuanced responses and strong reasoning. Popular in professional and enterprise settings. Growing importance for GEO.
Anthropic's web crawler used to gather content for Claude AI. Respects robots.txt directives. User agent: ClaudeBot or Claude-Web.
A nonprofit that maintains an open repository of web crawl data. Many AI models use Common Crawl data for training, making it an important source for AI visibility. Crawler: CCBot.
Optimizing content to be understood, cited, and recommended by AI. Includes content structure, writing style, FAQ optimization, and creating authoritative resources.
The amount of text an LLM can consider at once when generating a response. Includes conversation history and retrieved content. Limited context windows mean concise, well-structured content performs better.
Searching by having a conversation with AI rather than typing keywords. Users ask questions, get answers, and ask follow-ups. Requires different optimization than keyword-based search.
Microsoft's AI assistant, powered by OpenAI technology. Built into Windows, Edge, and Microsoft 365. Major presence in enterprise AI.
The amount of resources search engine and AI crawlers allocate to crawling your site. Large sites need to ensure important content gets crawled within budget limitations.
Public relations focused on earning online coverage and mentions. For GEO, digital PR builds citations, authority, and training data presence.
Experience, Expertise, Authoritativeness, Trust. Google's quality framework that also applies to GEO. AI systems have learned to recognize and prioritize E-E-A-T signals.
A distinct, identifiable thing that AI can recognize — such as a brand, person, product, or concept. Strong entities have consistent names, clear categories, defined relationships, and presence across authoritative sources.
The practice of building and strengthening your brand's entity so AI systems can accurately identify, understand, and recommend it. Includes ensuring consistent naming, clear categorization, and presence in authoritative sources.
Highlighted answers that appear at the top of Google search results. Often pulled into AI Overviews. Optimizing for featured snippets supports both SEO and GEO.
Additional training of an AI model on specific data to improve performance for particular tasks. Some organizations fine-tune models on their own data.
Google's AI model and assistant. Powers Google's AI Overviews and standalone Gemini app. Deeply integrated with Google Search.
Search experiences where AI generates synthesized answers rather than showing a list of links. Includes ChatGPT, Perplexity, and Google's AI Overviews.
Generative Engine Optimization. The practice of optimizing your brand, content, and digital presence to be discovered, understood, and recommended by AI-powered search systems like ChatGPT, Claude, and Perplexity.
An assessment of your current AI visibility, including how AI describes your brand, whether you're recommended, competitor analysis, and technical AI accessibility.
A Google crawler user agent that allows websites to block AI training (Gemini/Bard) while still allowing Google Search crawling. Provides granular control.
OpenAI's web crawler used to gather content for ChatGPT training and web browsing features. Can be controlled via robots.txt. User agent: GPTBot.
Connecting AI responses to real, verifiable sources of information. RAG and citations are grounding techniques that reduce hallucinations.
When AI generates false or inaccurate information that sounds confident and plausible. A risk for brands — AI might say incorrect things about you. Monitoring and correction strategies are part of GEO.
The date after which an AI model has no training data. Events, products, or information after the cutoff aren't in the AI's base knowledge — though some AI can search the web for current information.
A structured database of entities and their relationships. Google's Knowledge Graph, Wikidata, and similar systems help AI understand how things connect. Being in knowledge graphs improves AI's understanding of your brand.
Large Language Model. The AI technology behind ChatGPT, Claude, Gemini, and other AI assistants. LLMs are trained on massive text datasets and generate human-like responses by predicting the most likely next words based on patterns learned during training.
Large Language Model Optimization. Another term for GEO, emphasizing the LLM technology. GEO is more widely adopted.
An emerging standard for providing AI-specific instructions and context about your website. Similar to robots.txt but designed for LLM crawlers. Still in early adoption.
AI that can understand and process multiple types of content — text, images, video, and audio. Users can show AI a photo and ask questions. Visual and audio content matter for GEO.
NLP. The AI technology that enables machines to understand human language. LLMs are advanced NLP systems that power modern AI assistants.
Information 'baked into' an AI model during training. Always available without searching. Contrasts with retrieved knowledge from real-time search.
An AI search engine that always searches the web and cites sources. Shows which websites informed its answers. Important for GEO because citations are visible to users.
Perplexity AI's web crawler used for real-time search results. Very active since Perplexity always searches the web. Important for citation visibility.
The input a user gives to an AI system. In GEO, understanding how users prompt AI (what questions they ask, how they phrase them) helps optimize content to match.
Retrieval-Augmented Generation. A technique where AI searches for and retrieves relevant information from external sources (like the web) before generating a response. This allows AI to access current information beyond its training data.
AI systems that suggest products, services, or content to users. AI assistants increasingly function as recommendation engines, making GEO essential for being recommended.
A file that tells web crawlers which pages they can or cannot access. Used to control AI crawler access. Located at yourdomain.com/robots.txt.
A specific vocabulary (Schema.org) for structured data. Common types include Organization, Product, Article, FAQ, and Review schemas. Helps both SEO and GEO.
Whether AI responses about your brand are positive, negative, or neutral. Tracking sentiment across AI platforms is a key GEO metric.
Search Engine Results Page. The page of results shown after a search query. AI Overviews and featured snippets are SERP features that blend SEO and GEO.
Code (usually Schema.org markup) that explicitly tells search engines and AI what your content means. Helps AI understand entities, relationships, and content types.
The technical aspects of GEO — AI crawler access, structured data, site architecture, llms.txt implementation, and other technical optimizations for AI discovery.
The basic unit LLMs use to process text. Words are split into tokens (often word parts). Common words and brands get their own tokens. Context windows are measured in tokens (e.g., 128K tokens).
The massive dataset of text (web pages, books, articles) used to train an LLM. Information in training data becomes part of the AI's 'knowledge.' Your brand needs to be present in quality training data sources to be known by AI.
What a user is actually trying to accomplish with their query. Understanding intent — informational, transactional, navigational — helps create content AI will recommend for the right queries.
A free, collaborative knowledge base that provides structured data to Wikipedia and many other services. Being in Wikidata helps AI understand your brand as an entity.
The free encyclopedia that's a major source for AI training data. Having a Wikipedia page significantly increases AI visibility and entity recognition. Requires meeting notability guidelines.
When users get their answer directly from search results (or AI) without clicking through to a website. AI search often provides zero-click answers, making brand mentions valuable even without traffic.
