Why it matters to a buyer
Grounded answers hallucinate less and stay current in a way a model's frozen training data cannot, since training data has a cutoff date but grounding pulls in whatever is live on the web right now, which is exactly why a business's current pricing, hours or offerings are more likely to be represented accurately in a grounded answer than in one drawn only from what a model happened to absorb during training. A buyer's content strategy should specifically target the grounded, retrieval-based route, since that is the part of an answer engine's behaviour that content published today can actually influence.
How it is measured or applied
Grounding works by running a search at the moment of the query, retrieving a set of current pages, and generating a response constrained to reflect what those pages actually say, with citations pointing back to them. Content earns inclusion in grounded answers the same way it earns any AI citation: by being crawlable, directly answering the likely underlying question, and carrying clear, checkable facts. It is observed indirectly, since no vendor publishes which specific searches fed a given grounded answer, so tracking relies on running prompts with web search enabled and recording which sources get cited.
