What Is LLM SEO? How to Get Your Brand Into AI Answers

LLM SEO is the work of getting your brand named when people ask ChatGPT, Gemini or Perplexity for a recommendation. Here's what it involves.

Key takeaways

  • LLM SEO means optimising for the large language models behind ChatGPT, Gemini, Perplexity and Google's AI answers.
  • It overlaps heavily with GEO and AEO: the names differ, the work is largely the same.
  • Models name brands that are described consistently and vouched for by trusted third parties.
  • Measure it by testing a fixed set of buyer questions every month.

What LLM SEO means

LLM stands for large language model, the technology behind ChatGPT, Gemini, Claude, Perplexity and Google's AI Overviews and AI Mode. LLM SEO is the work of making your brand easy for these systems to find, understand and recommend when someone asks a question your business can answer.

You will also see it called generative engine optimisation (GEO), answer engine optimisation (AEO) or AI search optimisation. The labels differ but the work overlaps almost completely. Our complete guide to GEO covers the wider discipline.

How language models decide which brands to name

When an AI assistant answers a question, it draws on what it learned in training and, increasingly, on live search results. Either way, it favours brands it can be confident about: brands described consistently across the web, covered by trusted publications, reviewed by real customers and clearly explained on their own sites.

Five things that improve LLM visibility

Consistent description. Say what you do, for whom and where in the same words on your site, profiles and press materials.

Answer-first pages. Answer the questions buyers ask plainly, near the top of the page, so a model can quote you accurately.

Third-party proof. Press coverage, reviews and inclusion in comparison articles give models independent evidence.

Structured data. Organisation, service or product and FAQ schema help machines read your pages.

Crawlable content. Make sure key pages are not blocked and load fast. See what llms.txt is for one emerging signal.

How to measure it

Write down 20 to 30 questions your buyers ask, run them through the main AI assistants every month and record whether your brand is named and how it is described. Track searches for your brand name alongside it. Our guide to measuring citation share explains the method.
