What Is LLM in SEO?

LLM SEO refers to optimizing content specifically so large language models like ChatGPT and Claude are more likely to reference or cite it when generating answers to user questions. It matters because a growing share of research and buying decisions now start with a question to an AI assistant rather than a traditional search box.

The practical approach overlaps significantly with strong traditional SEO: clear structure, direct answers near the top of content, and genuine expertise on the topic. What differs is measurement, since ranking position no longer captures the full picture when a citation inside an AI answer can drive real traffic without a traditional click.

Building content aimed at both signals is central to how agency SEO software approaches every page.
