Zero-click search

A zero-click search is a search that ends without the searcher clicking any result. The person may have found the answer on the results page or in an AI summary, given up, or searched again.

How common it is

In a SparkToro study of US Google searches in the first four months of 2026, based on Similarweb's clickstream panel, 68% ended without a click of any kind. The author attributes the rise mainly to the growth of AI Overviews. The data leaves out the Google mobile app, so the real share is probably higher.

AI summaries also reduce clicks on the results that remain. Pew Research Center found that people who saw a Google AI summary clicked a traditional result in 8% of visits, against 15% when there was none, and clicked a link inside the summary in 1% of visits. Ahrefs found that the presence of an AI Overview correlates with a 58% lower average click-through rate for the top-ranking page.

Why it matters

When fewer searches end in a click, traffic undercounts your reach. A buyer can read an answer that names your brand, never click, and search for you by name later. The answer becomes the place where you are compared, so you need to know what it says.

How to measure it

Measure presence as well as visits:

• AI visibility: how often AI answers name you for the prompts you track.
• Impressions: Search Console's Generative AI performance report counts how many times links to your site were shown in AI Overviews and AI Mode.
• Branded search: rising Search Console impressions for your brand name can show that people heard about you somewhere.
• AI referral traffic: the visits that do arrive from AI assistants.
