What is TTFB by checkout
TTFB by checkout breakdown measures server responsiveness at the checkout funnel point. Time to First Byte (TTFB) is the time from request start until the first byte of the response is received.
Healthy TTFB by checkout sample
Should you worry
In a healthy view, checkout responds quickly from the server edge so rendering can start immediately, even under load.
Unhealthy TTFB by checkout sample
If TTFB is slow, heavy server-side work (pricing, taxes, inventory, personalization), cold starts, or regional latency can hold back the entire experience.
Resolving unhealthy TTFB by checkout
Go-to action plan to resolve an unhealthy TTFB by checkout:
Ask Uxi to analyze your TTFB by checkout values and suggest improvements.
Use Filters to focus on regions, routes, or templates with elevated TTFB.
Simulate TTFB of the suspected breakdown to see if fixing it will resolve the TTFB by checkout. If yes, this is where the resolution focus should be.
Use an automated optimization tool like Navigation AI to improve your TTFB by checkout values.
Once you’ve improved TTFB, set an alert to be the first to know if it starts worsening again.
