Introduction to Core Web Vitals
The Core Web Vitals Technology Report provides insights into the top-ranked content management systems by Core Web Vitals (CWV) for the month of June. This report is significant because it highlights the performance of various content management systems, including their ability to provide a good user experience. A key aspect of this report is the comparison of Interaction to Next Paint (INP) scores, which measure how quickly a website responds visually after a user interacts with it.
What are Core Web Vitals?
Core Web Vitals are a set of metrics that measure the performance of a website. They include metrics such as Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). These metrics provide insights into the loading speed, interactivity, and visual stability of a website. The Core Web Vitals Technology Report combines data from the Chrome UX Report (CrUX) and HTTP Archive to provide a comprehensive view of website performance.
How are Core Web Vitals Measured?
The Core Web Vitals Technology Report uses data from two public datasets: Chrome UX Report (CrUX) and HTTP Archive. CrUX obtains its data from Chrome users who opt into providing usage statistics reporting as they browse over 8 million websites. HTTP Archive, on the other hand, obtains its data from lab tests by tools like WebPageTest and Lighthouse that analyze how pages are built and whether they follow performance best practices.
Top-Performing Content Management Systems
The top-performing content management system is Duda, with a remarkable 83.63% of websites on the Duda platform receiving a good CWV score. Duda has consistently ranked #1, and this month continues that trend. Shopify is the next top performer, with 75.22% of Shopify websites receiving a good CWV score. This is extraordinary because shopping sites are typically burdened with excessive JavaScript to power features like product filters, sliders, image effects, and other tools that shoppers rely on to make their choices.
Interaction to Next Paint (INP) Scores
INP scores measure how quickly a website responds visually after a user interacts with it. A good INP score correlates with a better user experience because of how quickly the website performs. The top-ranked content management system for INP scores is Squarespace, with 95.85% of Squarespace sites achieving a good INP score. This indicates an excellent user experience for Squarespace websites.
