Read VLVTN Performance and Load-Time Scores
What the load-time scores mean
The performance overview lists your smart links with their speed metrics, sorted slowest first:
- TTFB — time to first byte, how quickly the server starts responding.
- FCP — first contentful paint, when the page first shows something.
- LCP — largest contentful paint, when the main content has loaded.
These are Real User Monitoring (RUM) measurements taken from your actual visitors, and they are shown against color-coded thresholds so you can spot a slow link at a glance.
Why load time matters
Speed matters most for paid-ad funnels. When you send paid traffic to a link, a slow page loses clicks before they convert, so every extra second of load time eats into the return on your ad spend. Keeping LCP, FCP, and TTFB low protects the clicks you paid for.
Reading the numbers carefully
Frequently asked
What are LCP, FCP, and TTFB?
Page-speed metrics. TTFB is time to first byte (how fast the server responds), FCP is first contentful paint (when something first appears), and LCP is largest contentful paint (when the main content has loaded).
Where do these numbers come from?
They are Real User Monitoring (RUM) measurements collected from your actual visitors, not a synthetic lab test.
Why might the numbers swing around?
Low sample count leads to high variance. With only a few visitors, one slow connection can move the averages, so read low-traffic links with caution.
Can I see per-link performance detail?
The per-link performance detail is a Pro feature. The overview list of all links with their load times is available more broadly, sorted slowest first.
