## LLMO / GEO guides

- [What LLMO is](https://stellagent.ai/insights/llmo): The overview. How an LLM assembles an answer, the two routes information reaches it by, and the four layers of the work — reach, comprehension, selection, measurement.
- [How LLMO, GEO, AIO and AEO relate](https://stellagent.ai/insights/llmo-geo-aio-aeo-difference): The four labels refer to nearly the same work. Where they genuinely diverge.

- [Structured data for e-commerce](https://stellagent.ai/insights/ec-structured-data-guide): Why to implement it — not for AI citations, but against misreading.
- [Merchant Center and product feeds](https://stellagent.ai/insights/merchant-center-product-feed): From ad plumbing to AI source data, and how Google's feed differs from ChatGPT's.
- [E-commerce SEO in the AI era](https://stellagent.ai/insights/ec-seo-ai-era): Designing for three readers — people, Googlebot and AI crawlers — and the four places their requirements conflict.
