CitenzoGrounding
When an AI engine bases its answer on retrieved sources rather than only its training data — the mechanism that produces citations.
Grounding is when an AI engine backs its answer with retrieved, real-world sources instead of relying only on what it memorized during training. Grounded answers can cite where each claim came from, which is why search-connected engines like Perplexity and ChatGPT Search show sources.
Grounding is central to GEO: if an engine grounds its answer in sources that mention you, you get cited. If those sources don't mention you, you don't.
