Unlike traditional SEO which targets Google rankings, GEO focuses on how AI systems perceive and recommend your brand. ### [AI Share of Voice](https://www.brandvector.io/glossary/ai-share-of-voice) AI Share of Voice measures the percentage of AI-generated recommendations and responses that mention your brand compared to competitors for relevant industry queries. It quantifies your brand's presence in AI assistant outputs like ChatGPT, Claude, and Perplexity, serving as the AI-era equivalent of traditional market share metrics. ### [Answer Engine Optimization (AEO)](https://www.brandvector.io/glossary/answer-engine-optimization) Answer Engine Optimization (AEO) is the strategy of structuring content to appear in direct answer formats used by AI assistants, voice search, and featured snippets. AEO focuses on providing concise, authoritative answers that AI systems can extract and present directly to users without requiring click-throughs. ### [AI Brand Monitoring](https://www.brandvector.io/glossary/ai-brand-monitoring) AI Brand Monitoring is the systematic process of tracking and analyzing how artificial intelligence language models mention, describe, and recommend a brand in their responses. This includes monitoring visibility across ChatGPT, Claude, Perplexity, and other AI assistants to understand brand perception in the AI ecosystem. ### [LLM Optimization](https://www.brandvector.io/glossary/llm-optimization) LLM Optimization encompasses strategies and techniques for improving how Large Language Models perceive, understand, and recommend a brand or product. This includes optimizing content structure, citation sources, and entity clarity to increase favorable mentions in AI-generated responses from systems like GPT-4, Claude, and Gemini. ### [Zero-Click Search](https://www.brandvector.io/glossary/zero-click-search) Zero-Click Search refers to search queries where users receive complete answers directly from search results, AI assistants, or featured snippets without clicking through to any website. This phenomenon has grown significantly with AI chatbots providing comprehensive responses, fundamentally changing how brands must approach visibility and traffic acquisition. ### [AI Traffic Attribution](https://www.brandvector.io/glossary/ai-traffic-attribution) AI Traffic Attribution is the process of identifying and measuring website visitors who arrive via AI assistant recommendations, such as clicks from ChatGPT, Claude, or Perplexity responses. This traffic typically appears as 'direct' in analytics tools, requiring specialized tracking to properly attribute and analyze. ### [Citation Share](https://www.brandvector.io/glossary/citation-share) Citation Share measures the percentage of times a brand is cited or referenced when AI language models respond to relevant industry queries. It tracks not just mentions, but instances where AI explicitly attributes information or recommendations to your brand, indicating authoritative positioning in AI-generated content. ### [GPTBot](https://www.brandvector.io/glossary/gptbot) GPTBot is OpenAI's web crawler for collecting content that may be used to train its generative AI models. It is separate from OAI-SearchBot, which decides whether your site can appear in ChatGPT search answers, and from ChatGPT-User, which visits pages when a ChatGPT user asks it to. Blocking GPTBot opts your content out of training; it does not remove you from ChatGPT search. ### [PerplexityBot](https://www.brandvector.io/glossary/perplexitybot) PerplexityBot is Perplexity AI's web crawler that indexes content for their AI-powered answer engine. Unlike ChatGPT, Perplexity always cites sources in responses, making PerplexityBot crawl access crucial for earning citations. It crawls more aggressively than GPTBot and focuses on extracting quotable, citable content for real-time search results. ### [ClaudeBot](https://www.brandvector.io/glossary/claudebot) ClaudeBot is Anthropic's web crawler that collects data for Claude AI models. Using user-agent strings 'ClaudeBot' and 'anthropic-ai', it operates more conservatively than GPTBot or PerplexityBot. Claude relies heavily on training data rather than real-time browsing, making ClaudeBot's historical crawls important for long-term visibility in Claude's recommendations. ### [llms.txt](https://www.brandvector.io/glossary/llms-txt) llms.txt is an emerging file standard that provides AI crawlers with a structured, machine-readable summary of a website's key information. Placed at the domain root (yourdomain.com/llms.txt), it helps AI systems quickly understand your brand, products, and value proposition without crawling your entire site. Think of it as a robots.txt for AI understanding, not just access. ### [Entity Optimization](https://www.brandvector.io/glossary/entity-optimization) Entity optimization is the practice of establishing a clear, consistent, and authoritative digital identity for your brand across all sources AI systems reference. This includes knowledge graph presence, Wikipedia entries, consistent naming across platforms, and schema.org markup—all helping AI confidently identify and recommend your brand. ### [Topical Authority](https://www.brandvector.io/glossary/topical-authority) Topical authority is the measure of a website's expertise and comprehensive coverage of a specific subject area. For AI visibility, building topical authority means creating deep, interconnected content clusters that establish your brand as the go-to expert on topics relevant to your industry, making AI more likely to cite and recommend you. ### [E-E-A-T](https://www.brandvector.io/glossary/e-e-a-t) E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness—Google's framework for evaluating content quality. For AI visibility, E-E-A-T signals help AI systems determine which sources to cite and recommend, making it essential to demonstrate real-world experience, expert credentials, authoritative standing, and trust signals across your content. ### [AI Crawler](https://www.brandvector.io/glossary/ai-crawler) AI crawlers are web bots operated by AI companies to index content for language models and AI-powered search. Key crawlers include GPTBot (OpenAI), ClaudeBot (Anthropic), PerplexityBot (Perplexity AI), and Google-Extended (Google). Managing access via robots.txt determines whether AI systems can access your content for training and real-time responses. ### [Google-Extended](https://www.brandvector.io/glossary/google-extended) Google-Extended is Google's user-agent specifically for AI training data collection, separate from Googlebot used for Search indexing. Blocking Google-Extended prevents your content from training Gemini and other Google AI products but does not affect Google Search rankings or AI Overviews. It's the rare AI crawler that lets you opt out of training without losing search visibility. ### [AI Content Optimization](https://www.brandvector.io/glossary/ai-content-optimization) AI content optimization is the practice of structuring and writing content specifically for extraction by AI systems. This includes using inverted pyramid structure, creating 40-60 word answer blocks, writing question-based headers, avoiding pronouns in opening sentences, and formatting information in easily quotable chunks that AI can cite directly. ## FAQ ### What is BrandVector? BrandVector is a resource for AI search visibility: how brands get mentioned and recommended by ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews. We publish platform guides and a glossary, offer free tools like the AI Visibility Checker and llms.txt Generator, compare AI visibility tracking tools, and match businesses with specialists who can improve their AI visibility. ### Does BrandVector still offer an AI visibility tracking product? No. BrandVector previously offered an AI visibility tracking subscription, which has been discontinued. If you need ongoing tracking, our AI visibility tools directory compares the leading options on pricing, engines covered, and features. ### Are your tool comparisons unbiased? Our comparisons are based on each vendor's published pricing and feature information, and every listing shows when it was last verified. Some outbound links are affiliate links, and vendors can pay for a clearly labeled Featured placement. Neither affects the order or content of our comparisons. ### How does BrandVector make money? Through affiliate commissions when you sign up for a tool via our links, clearly labeled sponsored listings, and referral fees from partner specialists when we introduce them to businesses that request help. All of our guides and free tools are free to use. ### How does expert matching work? Tell us about your website, goals, budget, and timeline using the Get Expert Help form. We review every request and introduce you to up to three AI visibility (GEO) specialists that fit your needs. You decide whether to work with any of them. ### Does it cost anything to request help? No. Requesting help and receiving introductions is free and there is no obligation. If you hire a specialist, you agree on pricing directly with them. ### What happens to the information I submit? We only share your request with the specialists we introduce you to, and only if you consent on the form. We don't sell your information. See our privacy policy for details. ### What is AI visibility? AI visibility is how often and how favorably AI assistants like ChatGPT, Claude, Perplexity, and Google AI Overviews mention or recommend your brand when people ask questions in your category. As more buyers research with AI, being recommended there works like ranking on the first page of Google. ### What is generative engine optimization (GEO)? Generative engine optimization (GEO) is the practice of improving how AI-powered search engines understand, cite, and recommend your brand. It combines technical access for AI crawlers, clear and well-structured content, and earning mentions on the sources AI models rely on. Our GEO guide covers it in depth. ### How can I check whether ChatGPT mentions my brand? Ask ChatGPT, Claude, and Perplexity the questions your customers would ask, such as 'best [category] for [use case]', and note whether and where your brand appears. Our free Prompt Generator creates a list of prompts to test, and the AI Visibility Checker shows whether AI crawlers can access and understand your site. For ongoing tracking, use an AI visibility tool. ### How long does it take to improve AI visibility? Technical fixes like allowing AI crawlers in robots.txt can take effect within weeks for AI search features that browse the web. Changes that depend on model training data or on earning mentions from other sites usually take several months. ### Do I need a paid AI visibility tool? Not to get started. Manual testing with a consistent set of prompts tells you where you stand. Paid tools become useful when you need to track many prompts across several AI engines over time, monitor competitors, or report results to clients or stakeholders. ### Are BrandVector's tools really free? Yes. The AI Visibility Checker, llms.txt Generator, and Prompt Generator are free and don't require an account. The AI Visibility Checker is limited to a few checks per day to prevent abuse. ### What does the AI Visibility Checker check? It checks whether AI crawlers like GPTBot, ClaudeBot, and PerplexityBot are allowed by your robots.txt, whether your site has an llms.txt file, how well your pages can be crawled and parsed, your Open Graph tags, and your internal linking, and it combines these into an AI visibility health score. It also suggests prompts you can test in ChatGPT and Perplexity to see whether they mention your brand.
