What is GEO vs SEO vs AIO?

GEO, SEO, and AIO describe overlapping but distinct goals. SEO is the practice of ranking a page in Google's organic results. GEO, generative engine optimization, is the practice of getting that same content quoted or summarized inside ChatGPT, Gemini, or an AI Overview.

AIO, sometimes written as AI optimization, is a broader and less standardized umbrella term some marketers use to cover any effort aimed at AI visibility, including GEO. It does not have a fixed technical definition the way SEO does.

In practice most teams do not run three separate strategies. They build one strong content foundation, then check it against both ranking factors and citation factors, since the two overlap on things like clarity, structure, and credible sourcing.

A software for GEOchecks a page against both sets of factors in one pass.
