Best CMS for Core Web Vitals

Among the leading content management systems (CMS), Squarespace, WordPress, and Wix have shown the most significant improvement compared to last year’s January 2024 core web vitals scores.

Core Web Vitals measure how quickly a website loads and performs. The Core Web Vitals Technology Report compiles these scores, combining real-world performance data from the Chrome UX Report (CrUX) dataset and lab measurements from the HTTPArchive dataset to provide accurate insights into website performance across different CMS platforms.

This article compares the core web vitals scores of Drupal, Duda, Joomla, Squarespace, Wix, and WordPress from January 2023 to January 2024.

The growth rate calculates improvements over two years by determining the percentage increase between the 2023 and 2024 scores. ChatGPT computes these percentages, which are then cross-checked with Google Gemini, offering insight into the rate of improvement across CMS platforms.

Keep in mind: Growth rate percentages might not match absolute rate differences. Absolute differences show the actual change in percentage points between two years, while growth rate percentages offer a broader perspective on performance enhancements over time.

“The formula for growth rate is expressed as follows:”

Year over Year Rates of Improvement

The year-over-year (YoY) improvement scores indicate each CMS’s improvement rate.

Squarespace – 54% Growth Rate

The growth rate jumped from 34.7% in 2023 to 54% in 2024, marking a remarkable increase of 55.62%.

This percentage signifies a 55.62% rise compared to the 2023 score of 34.7% and the 2024 score of 54%.

The absolute difference in percentage points between 34.7% and 54% is 19.3 points.

WordPress – 28.29% Growth Rate

In January 2023, 30.4% of WordPress sites demonstrated good core web vitals performance. By 2024, this figure surged to 39.0%. This increase from 2023 (30.4%) to 2024 (39.0%) represents a growth rate of 28.29%. The absolute percentage difference between 2023 and 2024 (30.4% vs. 39.0%) amounts to 8.6%.

Duda – 7.50% Growth rate

Duda achieved a growth rate of 7.50%, securing the fifth position in the comparison between 2023 and 2024. The increase from 70.7% passing CWV in 2023 to 76.0% in 2024 reflects this improvement. Despite Duda-built sites already boasting exceptionally high core web vitals scores, the platform continued to enhance its performance year over year.

Changes In Number Of Measured Sites

In 2024, Drupal’s higher scores were the result of measuring fewer websites, with approximately 129,000 Drupal sites measured compared to 147,000 in 2023.

These scores align with usage data reported on Drupal.org, which indicates a year-over-year decrease in usage from 981,659 sites in 2023 to 795,595 sites in 2024, marking a total decline of 186,064 Drupal websites.

WordPress also had slightly fewer measured sites, with a difference of 20,368 measured WordPress websites.

Joomla saw a decline of 30,243 measured websites, while the number of measured Duda sites remained stable, with only a slight decrease of 52 measured websites.

According to the Core Web Vitals Technology report, Wix and Squarespace were the only platforms in the group that experienced increased measured sites between 2023 and 2024.

Leading in Core Web Vitals

Duda maintains its position as the leader in top core web vitals scores despite WordPress showing the highest growth rate among the six content management systems analyzed in the Core Web Vitals Technology report.
