8 Percent With a Summary, 15 Without
When an AI summary appears, the click rate halves. An independent research organisation measured this through actual behaviour: across more than sixty-eight thousand searches, users clicked a traditional result 8 percent of the time when a summary was present and 15 percent when it was not.
This is not an estimate. It is a direct record of what people did. That makes the finding solid. More than sixty-eight thousand searches were examined. The sample runs wide enough to generalise from.
What the Number Says
BU BÖLÜMÜN ÖZETİ
- The method is strong
- The gap is nearly double
- The rate is low even without a summary
Three findings.
The method is strong
Behaviour tracking rather than a survey. What people did was measured, not what they said. That closes the finding to argument. What people say and do often diverges. Behaviour data settles that gap. People misremember their own actions when asked directly.
The gap is nearly double
The distance between 15 and 8 percent is wide. When a summary appears, clicks fall by almost half. Different studies point the same way, so the direction is settled. The size gets debated but the direction does not. Everyone reaches the same conclusion. Clicking is falling and it looks permanent.
The rate is low even without a summary
This is the critical point. Without any summary the click rate still sits at 15 percent. So the whole problem does not come from new technology. Zero-click search was already climbing before it. The shift runs further back. New technology accelerated an existing trend. It did not create it. The underlying shift was already underway.
What the Headline Misses
BU BÖLÜMÜN ÖZETİ
- Summaries do not appear on every search
- Being cited is its own channel
- Some sessions end there
Three details.
Summaries do not appear on every search
This rate applies only where one shows up. Summaries cluster around information questions and appear less on local or purchase-intent searches. So the effect stays limited in those areas. Local businesses feel it less. Checking your own field matters. Sectors behave differently and the gap can be wide.
Being cited is its own channel
Your name can appear inside the summary. You get seen without a click. That effect shows up in no current measurement tool, and an unmeasured gain never enters the calculation. Yet brand awareness still builds. Direct searches can rise as a result.
Some sessions end there
The same study shows something else: after seeing a summary, some users abandon the search entirely. The answer has been received. That still counts as a contact if your name appeared. They may recall you on the next search.

- An hour of comparison
- First move: find which content is affected
- Next move: change the measure
Three steps.
An hour of comparison
Compare your impression and click figures across two years. Impressions rising while clicks fall is the typical picture, and your own numbers beat any general rate.
First move: find which content is affected
Did your informational pages fall, or all of them? Without that separation the intervention lands in the wrong place. Effort goes where it does nothing.
Next move: change the measure
Raw clicks no longer mean much alone. Measuring enquiries gives a truer indicator.
Clicks fell but being seen did not. The two need separating.
