What is LLM SEO?

Large Language Models (LLMs) like ChatGPT, Claude, Gemini, and Perplexity are changing how people find answers. Instead of scrolling through a list of blue links, users are increasingly relying on AI-generated responses—responses that are often pulled from a limited set of sources.

LLM SEO is the process of optimizing your content, authority, and entity signals so that your brand appears in AI-generated answers.

While traditional SEO targets Google’s algorithms, LLM SEO targets the training data, retrieval engines, and citation logic of AI systems. The goal is simple: increase the probability your brand is referenced as an authoritative source when someone asks AI a question in your niche.
