LLM Optimization (LLMO)
Also known as: LLMO, LLM SEO
LLM optimization (LLMO) is the practice of improving how often and how favorably your brand appears in answers from large language models like ChatGPT, Gemini, and Claude. It is largely a synonym for GEO and AEO, since the field has several overlapping names for the same craft.
LLM optimization (LLMO) is the work of shaping whether, and how well, your brand shows up in answers from large language models such as ChatGPT, Gemini, and Claude. If that sounds familiar, it should. LLMO is largely another name for generative engine optimization and answer engine optimization.
One craft, several names
Being honest about this saves confusion. The discipline arrived fast and got named in parallel by different people, so GEO, AEO, LLMO, and “AI SEO” all circulate for roughly the same thing. The distinctions are mostly emphasis. LLMO foregrounds the model, AEO foregrounds the answer, GEO foregrounds the generative engine. Most teams treat them as one field and pick whichever term their audience uses.
What the work actually is
Whatever you call it, the tasks rhyme with mature search engine optimization: make your site crawlable, publish content that answers real buyer questions cleanly, earn trustworthy citations, and keep your brand described accurately. The difference is the goal, being inside the answer rather than ranking a link, and the need to track each engine separately because they disagree. For the foundation, start with what GEO is.
Frequently asked questions
Is LLMO different from GEO and AEO?
In practice, no. LLM optimization, generative engine optimization, and answer engine optimization describe the same work: getting named and cited inside AI answers. The field is young, so several labels compete for the same discipline.
Why are there so many names for this?
The practice emerged quickly and independently across teams, so vocabulary has not settled. GEO, AEO, LLMO, and even AI SEO all point at the effort to be part of the answer rather than a link in a list.
What does LLMO involve day to day?
Publishing clear answer-first content, earning citations on sources the models trust, keeping your brand described accurately, and making your site easy for AI crawlers to read, then tracking how each engine responds over time.
