Two and a half years ago, I wrote in Search Engine Land that RAG was the future of search. That part aged well. What I didn't name back then is what's eating it now. Every major AI search platform — AI Mode, ChatGPT Search, Perplexity, Claude, Gemini Deep Research, Copilot — has quietly moved on from "query → retriever → top-k → answer." The retrieve-once-then-generate pattern is dead for the major platforms. What replaced it has (at least) five gatekeepers your content has to survive. Most teams can only see one of them. The other four are a black box behind a black box behind a black box. I talk about agentic RAG in great detail in this new post and I also share some code to replicate the agentic RAG pipeline and show you where your content may be falling out of the process. ipullrank.com/agentic-rag
