What is TTFB by bounce rate
TTFB by bounce rate lens compares backend response times between bounced and non-bounced sessions. Time to First Byte (TTFB) measures how fast your server responds — the first visible sign of performance.
Healthy TTFB by bounce rate sample
Should you worry
Equal TTFB across BR and Not BR sessions suggests your backend is performing well and not contributing to early exits.
Unhealthy TTFB by bounce rate sample
If bounced sessions consistently show slower TTFB, your server or CDN configuration may be slowing down key landing pages — before any visual element even appears.
A long server delay before rendering can increase perceived slowness, pushing users to abandon the session before even seeing your offer.
Resolving unhealthy TTFB by bounce rate
Go-to action plan to resolve an unhealthy TTFB by bounce rate:
Ask Uxi to analyze your TTFB by bounce rate values and suggest improvements.
Use Filters to find patterns by country, browser, or UTM source.
Simulate TTFB of the suspected lens to see if fixing it will resolve the TTFB by bounce rate. If yes, this is where the resolution focus should be.
Use an automated optimization tool like Navigation AI to improve your TTFB by bounce rate values.
Once you’ve improved TTFB, set an alert to be the first to know if it starts worsening again.
