LLM SEO (also searched as "SEO for LLM") is the practice of optimizing how large language models understand and represent your brand. The models behind ChatGPT, Gemini, Claude, and Perplexity build an internal picture of who you are, what you do, and whether you're worth recommending — LLM SEO is the work of making that picture accurate, consistent, and favorable.

It is the foundation beneath GEO and AEO. If a model is unsure what category you belong to or has conflicting information about you, no amount of answer formatting will get you recommended.

How language models 'see' your brand

An LLM doesn't store your website; it stores patterns learned from many sources that mention you. Consistent, corroborated signals across reputable sites become the model's confident understanding of your brand. Sparse or contradictory signals become uncertainty — and uncertain brands don't get recommended.

  • Entity consistency: the same name, category, and description everywhere you appear.
  • Corroboration: multiple credible third-party sources saying the same thing.
  • Specificity: concrete facts the model can attach to your entity.
  • Recency: current information so the model isn't relying on stale data.

LLM SEO vs traditional SEO

Traditional SEO optimizes pages for a ranking algorithm. LLM SEO optimizes the broader information environment so a model forms an accurate, recommendable understanding of your brand. Backlinks and content still matter, but so does how you're described in reviews, directories, comparisons, and press the model has likely ingested.

Where to begin with LLM SEO tools

You can't fix what you can't see. The starting point is auditing what the major models currently believe about your brand and where that diverges from reality or from competitors.

AI Brand Track is an LLM SEO tool that probes ChatGPT, Claude, Perplexity, and Gemini with real buyer prompts, measures how each represents and ranks you, and pinpoints the inconsistencies and gaps to fix first.
