What is LLMO?
LLMO stands for Large Language Model Optimization. It is one of three near-synonyms (with GEO and AEO) for the practice of getting cited by name in AI assistants like ChatGPT, Perplexity, Gemini, and Claude.
LLMO is GEO is AEO is AI SEO.
The four terms are mostly synonymous. They describe the same underlying practice: optimizing your brand and your content so that the large language models powering AI search will cite you by name when buyers ask category-relevant questions.
Different practitioners and agencies use different terms. GEO (Generative Engine Optimization) is the most common in B2B marketing. AEO (Answer Engine Optimization) is more common in technical SEO circles. LLMO is rarer but growing. AI SEO is the most search-friendly umbrella term.
Pick GEO or AI SEO if you are writing for buyers.
The buyer-facing terms are GEO and AI SEO. Use those in your homepage, your service pages, and your buyer-facing content. Use LLMO and AEO when you are writing for technical SEO audiences who already know what they mean.
