Generative Engine Optimization (GEO)
Generative Engine Optimization (GEO) is the practice of optimizing content, brand messaging, and digital presence to improve visibility and favorable mentions in AI-powered search engines and language models like ChatGPT, Claude, Perplexity, and Grok. Unlike traditional SEO which targets Google rankings, GEO focuses on how AI systems perceive and recommend your brand.

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)
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

This includes monitoring visibility across ChatGPT, Claude, Perplexity, and other AI assistants to understand brand perception in the AI ecosystem.

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
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
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
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.
