What's the difference between AISO, GEO, AEO, LLMO, and other terms?

“They are overlapping terms for optimizing visibility in AI-generated answers. AISO focuses broadly on AI search, GEO on generative engines, AEO on direct-answer visibility, and LLMO on large language models. The terminology varies, but the goal is similar: helping your brand become easier for AI platforms to understand, mention, cite, and recommend.”
