What is TTFB by bounce page
TTFB by bounce page shows how Time to First Byte (TTFB) values perform on pages where users bounced — meaning they didn’t go beyond the initial page.
This lens reveals whether slow server response times are impacting a user's very first impression of your site, causing them to leave before content even begins loading.
It only includes pages that had measurable traffic and a bounce event during the selected period.
High TTFB on bounce pages is a warning sign: if it takes too long just to start loading, many users won’t wait around.
Healthy TTFB by bounce page sample
Should you worry
A healthy TTFB by bounce page lens shows green performance across key landing pages. This means the server responded quickly, and bounces weren’t likely driven by backend delays.
Fast TTFB ensures that even single-page visits load promptly, preserving trust and opening the door to future engagement or conversions.
Unhealthy TTFB by bounce page sample
If bounce pages show high TTFB — especially high-traffic pages like homepage, landing campaigns, or blog posts — this suggests users are bouncing before content even begins to load.
Common reasons include:
Poor CDN configuration or lack of edge caching.
Slow server-side logic or database queries.
Redirect chains or heavy authentication processes at load time.
Improving TTFB on bounce pages can significantly reduce early abandonment and create better first-touch experiences.
Resolving unhealthy TTFB by bounce page
Go-to action plan to resolve an unhealthy TTFB by bounce page:
Ask Uxi to analyze your TTFB by bounce page values and suggest improvements.
Use Filters to focus on high-traffic pages with bounce activity and poor TTFB. Look at server region, device, or caching status.
Simulate TTFB of the suspected lens to see if fixing it will resolve the TTFB by bounce page. If yes, this is where the resolution focus should be.
Use an automated optimization tool like Navigation AI to improve your TTFB by bounce page values.
Once you’ve improved TTFB, set an alert to be the first to know if it starts worsening again.
