What are Core Web Vitals?

Core Web Vitals are a set of standardised metrics from Google that help developers understand how users experience a web page. While Core Web Vitals were created for developers, these tools can be used by all site owners because they break down the user’s real-world experience on a page.

Core Web Vitals identify user experience issues by generating a metric for three primary areas of user experience, including:

A Page Performance Score is a single metric that considers all of the important user experience metrics in Core Web Vitals. This score uses an aggregate scoring system across all mobile and desktop visits. It takes the weighted average to deliver a single score to understand pages that need closer examination quickly.

We tested 70 dental websites from across the UK and have outlined the scores below.

Dental practice website “Performance”

Page performance is a really important metric for user experience. However, just over 65% of the 70 websites we tested rated “poor”, i.e below 50 out of 100, and an extra 28% needed improvements. This meant that overall 93% were either poor or needed improvement.

Dental practice website “Accessibility”

This is often overlooked. In the tests we ran, around 50% of sites either needed improvements or were poor.
