What is GEO

Generative Engine Optimization, explained

Generative Engine Optimization (GEO) is the practice of making your brand visible in AI-powered search engines. When someone asks ChatGPT "what's the best project management tool" or searches Perplexity for "top CRM software," AI engines synthesize answers from across the web 鈥?and GEO ensures your brand is among the sources they cite.

Unlike traditional SEO, which focuses on ranking in blue links, GEO is about influencing how large language models describe and recommend your brand. Brand mentions correlate 3x more strongly with AI visibility than backlinks (Ahrefs study of 75,000 brands). The tools to monitor this are evolving fast 鈥?and we track them all.

Guides & resources

AEO

Answer Engine Optimization (AEO) is the practice of optimizing content to be selected as the direct answer in AI-powered search engines and answer platforms, including Google's featured snippets, voice search, and AI assistants.

Agentic Commerce

Agentic commerce is the emerging paradigm where AI agents autonomously research, compare, recommend, and even complete purchases on behalf of users — representing the convergence of GEO, e-commerce optimization, and AI-powered decision-making.

Agentic Search

Agentic search is the next evolution of AI-powered search where AI agents not only retrieve and synthesize information but also take action on behalf of users — making purchases, booking appointments, and completing multi-step tasks.

AI Crawler Accessibility

AI crawler accessibility refers to ensuring that AI search engine crawlers and bots can access, parse, and index website content — a technical prerequisite for appearing in AI-generated search responses.

AI Overviews

AI Overviews are Google Search's AI-generated summaries that appear at the top of search results, synthesizing information from multiple web sources into a single conversational answer with inline citations.

AI Search Engine

An AI search engine is a search platform that uses large language models and generative AI to synthesize answers from multiple sources, rather than returning a list of links like traditional search engines.

AI Share of Voice

AI Share of Voice (AI SOV) measures your brand's visibility across AI-powered search platforms relative to competitors, tracking how often your brand appears in AI-generated responses compared to other brands in your industry.

Brand Mentions

Brand mentions are references to a brand name in any context — including unlinked mentions — used by AI engines as signals for citation, recommendation, and topic association.
