What is TTFB by pageviews per session
TTFB by pageviews per session lens compares initial server response time across the user journey. Time to First Byte (TTFB) shows how long it takes your server to respond after a page is requested.
Longer sessions often mean more server requests. If TTFB degrades across pages, your infrastructure may be struggling to keep up.
Healthy TTFB by pageviews per session sample
Should you worry
If users consistently experience fast TTFB, even after 10+ pageviews, your backend is scaling smoothly. Spikes in TTFB for shorter sessions, on the other hand, can block conversions before they begin.
Unhealthy TTFB by pageviews per session sample
If TTFB increases with session depth, investigate caching gaps, session-based rendering, or overloaded APIs. If it’s poor for single-page sessions, prioritize landing page optimization and faster cold starts.
Resolving unhealthy TTFB by pageviews per session
Go-to action plan to resolve an unhealthy TTFB by pageviews per session:
Ask Uxi to analyze your TTFB by pageviews per session values and suggest improvements.
Use Filters to isolate slow segments across country, device, or browser.
Simulate TTFB of the suspected lens to see if fixing it will resolve the TTFB by pageviews per session. If yes, this is where the resolution focus should be.
Use an automated optimization tool like Navigation AI to improve your TTFB by pageviews per session values.
Once you’ve improved TTFB, set an alert to be the first to know if it starts worsening again.
