Generative artificial intelligence models such as ChatGPT, Gemini and Perplexity work in a specific way: they are trained on a vast but limited dataset up to a cut-off date (knowledge cut-off). For example, Gemini's knowledge cut-off is January 2025, while ChatGPT is frozen at October 2023.
When a user asks a question about a topic after the cut-off, the model does not have the answer in its training set. This is where Retrieval-Augmented Generation (RAG) comes into play: the AI searches online, analyzes traditional search engine results, selects the most authoritative sources and synthesizes an updated answer.
This process is what makes GEO SEO strategic: you cannot "enter" the static model, but you can optimize your retrieval-ready content to be the selected source when the AI activates RAG search in the context of SEO for artificial intelligence.
