It’s rare that in analyses of content management systems, WordPress doesn’t come out on top. But today, we’ll look at one report where the outright winner does not begin with a W.
Recently, HTTPArchive has recently published its latest rankings for the top performing content management system.
Before we dive into the top 5 content management systems for Core Web Vitals, a little bit on the data. Two datasets are used by HTTPArchive to arrive at its score when it comes to Core Web Vitals and content management systems.
These datasets are CRuX and Lab. CRuX data comes from the actual visits of a website by real users who have allowed their data to be collected anonymously for Core Web Vitals performance. Lab data comes from millions of websites in which the data simulates both mobile device and connectivity to reach a score.
These two datasets are combined together to determine the Core Web Vitals scores across all content management systems.
These are their results for the best CMS for Core Web Vitals.
Number one: Duda
Duda is a website building platform that gets organizations online and make a digital presence quickly, without having to worry too much about the underlying tech.
The ultimate goal of Duda is to provide customers with the ability to focus on their business while the platform handles the technology side.
When it comes to Core Web Vitals performance, Duda was no doubt the number one. The percentage of websites that are built on Duda that have a good Core Web Vitals performance is 77.3%.
This makes Duda the undisputed king of the Core Web Vitals, beating second place by more than 20%.
When it comes to other website builder platforms, Wix was in second place, with 54% of websites built on the platform having a good score.
“Using this data driven approach we were able to identify opportunities for improvements,” said a spokesperson for Duda. “We implemented those improvements and checked the improvement again using our BI tool. This was a successful iterative approach that helped us to increase scores over time.”
Number two: Drupal
Second in the rankings is the open-source Drupal platform, overtaking the position that was previously held by Wix.
This year, Drupal overtook Wix as 58% of websites that are built on the platform have good Core Web Vitals scores. This is an increase since last year, when its score measured 50.2%
Number three: Wix
Unfortunately for Wix, they’ve slipped down the list into third place when it comes to the amount of websites receiving good Core Web Vitals scores.
Last year, the percentage of Wix websites having a good core was 55.3% compared to this year’s scores, which slipped to 54%.
Number four: Squarespace
Squarespace has been going from strength to strength in recent years. In last year’s report, those websites that are built on Squarespace that received a good score across Core Web Vitals was 31.5%. This year, the amount of websites rose to 42.8%.
Number five: WordPress
Long the number one in terms of most used CMS, WordPress has to contend with being behind a number of competitors when it comes to the Core Web Vitals performance of its websites.
However, despite not changing position since last year, it has increased its percentage of websites that receive a good Core Web Vitals score.
Last year the number of websites having a good Core Web Vitals score was 31% before jumping to a strong percent of 37.4%.
That’s a good improvement from WordPress, which had been viewed as neglecting the intensity of focus when it came to improving Core Web Vitals. This year’s performance has shown that WordPress is now making strides when it comes to improvements.
