Speed is a ranking factor and a revenue factor
Slow pages lose visitors before the content even appears. Core Web Vitals tell you where that is happening.
Google’s yardstick, measured
Page speed is a confirmed Google ranking factor. WebYes reports the metrics behind it for every scanned page.
Five metrics, one view
FCP, LCP, TBT, CLS, and Speed Index, each shown against its good, needs improvement, and poor thresholds.
A score that tracks progress
A site-wide performance score with trend indicators shows whether each round of fixes moved you forward.
From slow metric to fix list
Every scan measures your vitals and turns the misses into issues you can work through.
Every metric, with its threshold
Each scanned page gets its Core Web Vitals measured on mobile and desktop, plotted against the good, needs improvement, and poor thresholds, so you see at a glance which metric is costing you.
- FCP, LCP, TBT, CLS, and Speed Index per page
- Thresholds shown against each metric
- Average response time tracked with trends
Lab today, real visitors tomorrow
Scan-based vitals show what to fix now. Pair them with Real User Monitoring and you also see how those fixes feel for actual visitors.

Slow pages lose visitors
Core Web Vitals are measured in every WebYes scan.
They are the metrics Google uses to judge how a page feels to use: how fast it loads, how quickly it responds, and how stable the layout is. WebYes measures them for every page in your scan.
FCP, LCP, TBT, CLS, and Speed Index for each scanned page, on mobile and desktop, each plotted against its good, needs improvement, and poor thresholds. Average response time is tracked alongside them.
No. Scan-based Core Web Vitals need nothing installed; WebYes measures your pages from the outside. Only Real User Monitoring, which captures data from actual visitors, uses a small snippet.
Scan-based vitals are lab measurements you run on demand, ideal for finding and verifying fixes. RUM measures real visits continuously. They complement each other, and both live in the same performance module.
Yes. Page speed is a confirmed Google ranking factor, and it directly affects bounce rates too. Improving your vitals helps both how you rank and how many visitors stay.
