What is LLM SEO?
SEO Definition and Examples
LLM SEO (or GEO) is optimizing content to be cited or recommended by AI models like ChatGPT, Perplexity or Google AI Overviews.
Full Definition: What is LLM SEO
LLM SEO (Large Language Model SEO), also known as GEO (Generative Engine Optimization), is an emerging discipline that optimizes content to be selected as a citable source by generative AI models. Unlike classic Google (which follows links), LLMs read the text and decide whether it is worth citing based on the clarity, specificity and credibility of the information. Key principles: clear definitions at the start of sections ("X is Y that does Z"), specific numeric data, cited sources, FAQ-style structure, tabular format and a robots.txt that allows AI crawlers (GPTBot, ClaudeBot, PerplexityBot).
Why Does LLM SEO Matter for SEO?
By 2026, an estimated 30-40% of searches with a direct answer will come from AI Overviews (Google) or chatbots (ChatGPT, Perplexity). Sites not optimized for LLMs lose a third of their potential organic visibility.
