Is LLM the Same as SEO?

No, an LLM and SEO are not the same thing at all. An LLM, a large language model, is the underlying AI technology behind tools like ChatGPT and Claude. SEO is the practice of making content easy for search systems to find and rank.

The two connect because LLMs are now one of those search systems. When someone asks ChatGPT a question instead of Googling it, the model retrieves and summarizes web content, which means the old SEO playbook now has a second audience beyond Google's crawler.

That second audience is what LLM SEO specifically targets, structuring content so a model can retrieve, trust, and quote it accurately.

Software built for that specific audience is software for AI search visibility, not a general writing assistant.
