What is TTFB by dead clicks
TTFB by dead clicks breakdown shows how Time to First Byte (TTFB) differs for sessions with dead clicks compared to those without them.
A dead click happens when a user clicks on an element that doesn’t trigger any action or feedback — like text, images, or icons that look interactive but aren’t. While often caused by design, slow server responses (high TTFB) can amplify the perception that nothing is happening.
This breakdown helps you identify whether slow TTFB is making dead clicks feel worse. If the page takes too long to start rendering after a click, users may assume the element was unresponsive.

Should you worry
In a healthy view, TTFB values for dead click sessions look similar to non-dead click sessions. Dead clicks may still occur, but they’re usually UX-related, not performance-driven.
A healthy setup typically shows:
TTFB consistently under 800ms across all sessions.
Server responses quick, even when users missclick.
Dead clicks caused by unclear design patterns rather than backend speed.
If TTFB is stable, dead clicks are a design problem, not a server performance problem.
Unhealthy TTFB by dead clicks
If dead click sessions consistently show higher TTFB values, slow server responses may be amplifying confusion.
Common causes include:
Server delays making valid interactions appear like dead clicks.
Uncached requests slowing down after user interactions.
Dynamic rendering taking too long to produce the first byte.
API latency making elements feel unresponsive.
Here, slow TTFB blurs the line between real dead clicks and perceived unresponsiveness.
Resolving unhealthy TTFB by dead clicks
Go-to action plan to resolve an unhealthy TTFB by dead clicks:
Ask Uxi to analyze your TTFB by dead clicks values and suggest improvements.
Use Filters to compare dead click sessions by device, country, or traffic type.
Simulate TTFB of the suspected breakdown to see if fixing it will resolve the TTFB by dead clicks. If yes, this is where the resolution focus should be.
Use an automated optimization tool like Navigation AI to improve your TTFB by dead clicks values.
Once you’ve improved TTFB, set an alert to be the first to know if it starts worsening again.
