Definition
A zero-click search ends without a click to any website: the answer is shown directly in the results, in a snippet, a knowledge panel or an AI-generated overview.
Why it matters
Your content can inform an answer without bringing a visit. Search traffic can fall while your content is used just as much.
The AI version
AI assistants work the same way: they read pages and answer in the chat. Some people click through; many don't. To see how often assistants read your pages, regardless of clicks, look at your server's traffic; see AI visibility.
