Zero-click search
Short definition
A zero-click search is one where the searcher finds their answer directly on the results page and never clicks through to a site.
For questions such as the weather, a time difference or a simple definition, a search engine shows the answer directly on the results page. As AI Overviews have spread, this behaviour now shows up on more complex questions too, a visitor can read the summary and leave without ever reaching a site.
This can shrink a site's visitor numbers even while it ranks well. A brand caught in these clickless searches now has to measure its visibility not by visits, but by whether it gets cited as the source inside that summary answer.
A query behind zero-click behaviour is not labelled directly in Google Search Console, it can only be inferred indirectly. When a page ranks well and gets plenty of impressions for a query but its click-through rate sits well below what would be expected, that pattern usually signals the answer is already showing on the results page itself.
Why it matters
The rise of zero-click search means measuring a site's traffic by clicks alone is no longer enough. Brand awareness can now be built inside an answer that gets seen but never clicked.
Illustrative example
A flooring manufacturer noticed its brand named inside a summary answer despite the search being zero-click, and shifted its measurement from clicks to how often the brand gets mentioned.
