Top 6 CMS for Core Web Vitals

HTTPArchive has published the latest rankings of the best performing Content Management Systems (CMS). We reviewed the rankings of six popular CMS and found that the best performing CMS outperforms its competitors by wide margins.

We continue to review the data related to the geographic region of the United States, as before.

The global data is slightly different from the US data, but not to the point of changing the ranking position of any of the CMS under review.

How Core Web Vitals CMS Ratings Are Determined

HTTPArchive uses two sets of data to arrive at the top rankings of vital web data from all content management systems.

The data sets used by HTTPArchive are:

  1. CRux data set
  2. Laboratory data set

CRux data set

The CRuX dataset comes from actual website visits by real people who have opted-in to anonymously allow Core Web Vitals data to be collected from the websites they visit.

Laboratory data set

The lab’s dataset comes from a crawler that collects data from millions of websites. Lab data simulates mobile devices and mobile connectivity to arrive at ranking scores.

These two data sets are used to determine the core web vitals scores for all CMS and are published for review.

#1 Core Web Vitals Champion: Doubt

Duda is a professional website building platform that enables businesses to connect quickly without having to think about the underlying technology.

The goal is to give customers the ability to focus on their business while Duda takes care of the technology. That’s an approach shared by other companies like Wix and Squarespace.

Of those three website building platforms, Duda still leads.

When we last checked the HTTPArchive technology report data, Duda was leading the pack by a significant margin.

This trend continues with the latest performance data being released, which is for February 2022.

The percentage of websites built with Duda that performed well on basic vital web data was an impressive 77.3%.

As of October 2021, the percentage of well-performing websites was 69.3%.

Duda’s performance benchmark improved by 8%.

A comparison of the three website building platforms in this review builds up like this:

Comparison of CWV Scores of SaaS Website Builders

  • Doubt 77.3%
  • Wix 54.0%
  • Square space 42.8%

Duda is not only leading the competition, but beating them by exceptionally wide margins.

Wix, the second-place competitor for website builders, trails Duda by more than 23 percentage points.

In a way, this shouldn’t be surprising because the last time we talked to Duda they indicated that website performance was an important goal for them.

They shared that they took a data-driven approach to identify areas for improvement and then implement updates to client websites so they could enjoy faster and better performance.

A spokesperson for Duda had shared:

“With this data-driven approach, we were able to identify opportunities for improvement.

We implement those improvements and verify the improvement again using our BI tool.

This was a successful iterative approach that helped us increase scores over time.”

Core Web Vitals Champion #2: Drupal

The second place CWV champion is the open source CMS Drupal, overtaking the second place previously held by Wix.

In the previous survey, the percentage of Drupal sites with a good Core Web Vitals score was 50.2%.

This year, Drupal outperforms Wix with a score of 58.2%, with Wix behind by four percentage points with a score of 54.0%.

#3 Core Web Vitals Champion: Wix

This time, instead of improving performance, the percentage of sites with a vital web core approved actually dropped.

This contributed to Wix dropping from position #2 to behind Wix in position #3.

In the latest survey, Wix performance was 55.3% of sites built with Wix and enjoyed a passing central web vitals score.

This year, Wix’s performance actually fell to 54.0%.

#4 Core Web Vitals Champion: Squarespace

Squarespace is moving forward with a strong performance improvement on its platform.

In the previous survey, Squarespace was ranked at 31.45% of sites that passed CWV. This time around, 42.84% of Squarespace sites have a passing CWV score.

#5 Core Web Vitals Champion: WordPress

WordPress clings to position n. 5, which is the same position he ranked in October.

WordPress performance increased from 31% to a whopping 37.4%.

That is a significant amount of improvement which may reflect the good work of the WordPress performance team that is working within WordPress to improve WordPress performance speed.

The WordPress Performance team recently released an experimental performance plugin as part of their effort to test performance improvements before they become the main core of WordPress.

Future versions of WordPress may see more improvements.

Champion #6 Core Web Vitals: Joomla

Joomla didn’t make the rankings the last time we polled HTTPArchive results.

According to HTTPArchive, Joomla had a score of 30.5% in September 2021, which is the date of results reported in October.

This time, Joomla jumps just behind WordPress with a score of 35%, just two percentage points behind WordPress.

Here are the top-ranked CMSs based on performance measured by Core Web Vitals:

Duda’s score of 77.3% is more than twice as good as fifth place WordPress, which is currently the most popular CMS in the world.

Clearly, if web performance is important to a business, there are CMSs other than WordPress to choose from.

But don’t write WordPress off just yet because its performance team is catching up fast.
