A zero-click search is a search that ends without anyone clicking a result, because the answer appeared on the results page itself: in an AI Overview, a featured snippet, a map pack, a weather card or a phone number. The searcher got what they came for and left, and no website recorded a visit.
Whether that is bad for you depends on what the search was for. A plumber whose number appeared in the map pack and got a call had a very good zero-click search. A blog that lost the click to a summary had a bad one. The term is neutral. The outcome is not.
