What is TTFB by navigation type
TTFB by navigation type shows the Time to First Byte (TTFB) across different navigation types — like Navigate, Back-forward, or Prerender. This lens helps you see how quickly the server responds when users arrive via different types of navigation.
The list only includes navigation types that brought traffic during the selected time period.
TTFB is the time between a user's request and the first byte of data received. It’s a key backend performance metric — especially for pages that aren't cached or prerendered.
Healthy TTFB by navigation type sample
Should you worry
A healthy TTFB by navigation type lens is all green — whether users are navigating normally or coming back via the back button. That means your server response is fast and consistent, regardless of how the user got to the page.
Unhealthy TTFB by navigation type sample
In the example below, the Navigate type shows slow TTFB. That often means your server or CDN isn’t fast enough to respond during first-time visits. This leads to a visible delay before the page even begins loading — a silent killer for perceived speed.
Resolving unhealthy TTFB by navigation type
Go-to action plan to resolve an unhealthy TTFB by navigation type:
Ask Uxi to analyze your TTFB by navigation type values and suggest improvements.
Use Filters to focus on the slowest navigation type, then switch to TTFB by page group or TTFB by country to identify bottlenecks.
Simulate TTFB of the suspected lens to see if fixing it will resolve the TTFB by navigation type. If yes, this is where the resolution focus should be.
Use an automated optimization tool like Navigation AI to improve your TTFB by navigation type values.
Once you’ve improved TTFB, set an alert to be the first to know if it starts worsening again.
