Large Language Model Optimization (LLMO) is the practice of shaping your content and online presence so AI language models mention, cite, or recommend your brand in their answers. It overlaps heavily with GEO and AEO, but its specific concern is how the model itself understands and represents you.
These acronyms are often used interchangeably, which breeds confusion. A rough way to separate them:
In practice the three reinforce each other, and most teams pursue them together.
You can't edit a model's weights, but you can shape the signals it learned from and the pages it retrieves. Suppose a boutique accounting firm wants ChatGPT to list it among options for freelancers. The work involves publishing clear, factual service pages, earning mentions in trade publications and roundups the model may have trained on, keeping brand details consistent everywhere, and marking up content with structured data so retrieval-based models can lift accurate facts.
LLMO is a close relative of generative engine optimization and depends on how each underlying large language model is trained and queried.
