What is TTFB by funnel points
TTFB by funnel points breakdown breaks down Time to First Byte (TTFB) by user journey funnel points — the key moments like landing, product, cart, and checkout that define how users move toward conversion.
TTFB measures how long your server takes to start responding. If TTFB is high at a specific funnel points, users may wait too long to see any part of the page — leading to early drop-offs or frustration at crucial stages.

Should you worry
In a healthy view, TTFB remains in the green across all major funnel points. That means your server is responding quickly no matter where the user is in the journey.
Even if response times vary slightly, the key is to avoid yellow or red, especially at high-traffic or high-intent funnel points.
Unhealthy TTFB by funnel points
When you see poor TTFB on key funnel points — like Checkout or Product — it usually points to:
Server-side personalization or authentication slowing down responses.
Uncached pages or API calls for logged-in users.
Backend logic delays for dynamic content or A/B test variations.
This adds friction during critical steps and increases the chance of exits.
Resolving unhealthy TTFB by funnel points
Go-to action plan to resolve an unhealthy TTFB by funnel points:
Ask Uxi to analyze your TTFB by funnel points values and suggest improvements.
Use Filters to pinpoint high-latency pages or user groups.
Simulate TTFB of the suspected breakdown to see if fixing it will resolve the TTFB by funnel points. If yes, this is where the resolution focus should be.
Use an automated optimization tool like Navigation AI to improve your TTFB by funnel points values.
Once you’ve improved TTFB, set an alert to be the first to know if it starts worsening again.
