How to read the Wix Site Speed dashboard

Wix’s dashboard has two parts, and they answer different questions.

• Real visitor experience: the Core Web Vitals recorded from people who actually loaded the site.
• Google PageSpeed simulation: an estimate from one simulated visit.

Real visitor experience is the half that matters. Wix collects it from every visit, in every browser, and shows an average for the past 30 days, for the whole site and page by page. Each measure carries a label set by Google’s thresholds: Good, Fair or Poor.

Two measures do most of the work. Largest Contentful Paint is how long the largest thing on screen takes to appear. Interaction to Next Paint is how quickly the page responds to a tap or click. Our guide to checking your website speed gives the marks for each.

The simulation is Google’s PageSpeed test run on the page. Wix describes what it does: Google simulates a low-end mobile device on a slow connection and estimates a score. Wix adds that a low score here does not mean the site is underperforming for real visitors.

A simulated score is useful for one thing: its list of what is slowing the page.

Wix’s advice is to focus on real visitor data wherever a page has enough traffic to produce it. Treat the real-visitor figures as the verdict and the simulation as the diagnosis. A page labelled Good for real visitors with a middling simulated score is fine. A page labelled Poor for real visitors has a problem whatever the simulation says.

The dashboard shows your site only. A ranking is a contest, and the useful comparison is with the sites beside you in the results. Google’s PageSpeed Insights tests any public address, so run your page and a competitor’s there, and compare the real-visitor section of each.

One difference matters when you do. Google’s real-visitor data counts visits made in Chrome, and Wix’s counts every browser, so the two figures for your own site will not match exactly.

If the real-visitor labels are Good, speed is not what is holding the site back. If they are Fair or Poor, work through how to speed up a Wix website and read the dashboard again a month later.
