RAG
Retrieval-Augmented Generation is the pattern of pulling relevant documents from a search index and feeding them into a language model at answer time. It is what powers most cited AI answers.
How does RAG decide whether to cite you?
Perplexity, ChatGPT browsing, Claude with web search, and Google AI Overviews all use retrieval-augmented generation. Rather than answering purely from memory, the engine first retrieves a set of documents from a live index, then writes its answer from those documents and cites them. That two-step shape is what makes GEO possible at all.
Your visibility in these engines is therefore a product of two things: whether your content is retrievable, meaning it is indexed, crawlable, and topically matched to the query; and whether, once retrieved, the model finds it useful and trustworthy enough to actually quote. You can be retrieved and still not cited if a competitor's page answers the question more cleanly.
Optimizing for both halves is the practical core of GEO: structure and technical health for retrieval, and clear, authoritative, directly-answering content for citation. GrowthManager builds pages with that two-step in mind and tracks which engines retrieve and cite you for each tracked query.
RAG also changes how freshness compounds. A traditional SEO page can rank for years off one strong publish. A RAG-targeted page benefits from continuous small updates: refreshed examples, current statistics, new comparison data points. Engines weight recency for many query types and the retrieval step penalizes pages whose timestamps drift months stale on time-sensitive topics. Plan for weekly content maintenance, not just initial publication, and watch citation share lift on the queries you keep current versus the ones you let coast.
