The Core Net Vitals Know-how Report by the open supply HTTPArchive neighborhood ranks content material administration methods by how effectively they carry out on Google’s Core Net Vitals (CWV). The July replace exhibits that each main platform has improved since June, however not all beneficial properties have been equal. Joomla posted the most important month-over-month enhance, whereas Duda ranked first in July with 84.96% of web sites passing CWV.
Why Core Net Vitals Matter
Core Net Vitals (CWV) are metrics created by Google to measure how briskly, secure, and responsive a web site feels to customers. Web sites that load rapidly and reply easily preserve guests engaged, whereas websites that fall quick frustrate customers and enhance bounce charges. For companies and publishers, CWV scores mirror the person expertise and competitiveness on-line.
How the Information Is Collected
The CWV Know-how Report combines two public datasets:
- Chrome UX Report (CrUX): Information from Chrome customers who choose in to share efficiency statistics as they browse. This displays how actual customers expertise web sites.
- HTTP Archive: Lab-based assessments that analyze how websites are constructed and whether or not they observe efficiency finest practices.
Collectively, these sources present a constant image of how totally different web site platforms carry out on Core Net Vitals in the true world.

Joomla confirmed the quickest progress, nevertheless it nonetheless ranked fifth in July. Duda led with the best general efficiency.
Why the Numbers Matter
Core Net Vitals scores translate into actual variations in how customers expertise web sites. Platforms with greater CWV scores supply sooner, smoother interactions, whereas these on the backside frustrate customers with slower efficiency. Whereas all six platforms within the comparability are enhancing month to month, what issues most is the precise expertise customers get proper now.
- Duda is the Core Net Vitals champion in July with a rating of 84.96% of internet sites constructed with the Duda platform having an excellent CWV rating.
- Joomla had the most important achieve, however nonetheless ranked close to the underside with solely 54.78% of web sites displaying an excellent CWV rating.
- Wix and Squarespace ranked within the second and third locations, displaying robust efficiency however each considerably behind Duda by over ten proportion factors.
- WordPress ranked final, each in July scores and within the month over month fee of enchancment.
Do Content material Administration Techniques Matter For Rating?
I’ve seen discussions on-line about whether or not the selection of content material administration system has an influence on rankings. Some folks assert that plugins make WordPress simpler to rank in Google.
There may be additionally a notion that WordPress is quicker than Wix, Duda, and Squarespace. The details, in fact, present that the other is true. WordPress is the slowest of the content material administration methods on this comparability.
The share of web sites constructed with Duda that had an excellent Core Net Vitals rating is 84.96%. The share of WordPress websites with an excellent CWV rating is 44.34%. Meaning Duda’s proportion of web sites with good CWV scores is about 92% greater than these constructed with WordPress.
One other difficulty with WordPress is that it has a substantial quantity of technical debt, one thing that personal content material administration methods shouldn’t have to wrestle with to the identical diploma. Technical debt refers back to the accumulation of outdated code and design selections that make it tougher to keep up, replace, or enhance the platform over time. It’s not distinctive to WordPress, nevertheless it is a matter due to how WordPress is constructed and the way its ecosystem works.
Some causes for WordPress’s technical debt:
- WordPress was initially conceived as a running a blog platform and has developed right into a full CMS, in a position to be prolonged as just about any type of web site.
- Including new options on high of legacy code means workarounds should be made for backward compatibility, which creates complexity and slows down innovation.
Technical debt was a problem mentioned at WordCamp EU 2025, summarized on the official WordPress website as associated to contributor burnout:
“Burnout Disaster & Sustainability
- Contributor burnout is pervasive attributable to:
- Excessive volunteer calls for with inadequate systemic help.
- Lack of equitable monetary remuneration or stipends for ongoing work.
- Strain to keep up legacy methods and innovate new options results in overwhelming workloads.
Penalties
- Lack of institutional information and skilled contributors.
- Growing technical debt and slowed innovation cycles.
- Menace to WordPress’s long-term ecosystem well being.”
WordPress has lately moved to a slower annual launch cycle, and one of many advantages of that change (summarized by WordPress right here) is that it provides the challenge time to deal with the difficulty of technical debt.
The purpose is that if the content material administration system did affect the power to rank, WordPress websites would most likely wrestle to rank due to the comparatively poor efficiency scores and the slower tempo of improvement when in comparison with personal content material administration methods like Wix. However that’s not the case.
WordPress web sites rank very effectively regardless of all the problems with the platform, together with safety. So it could be that the selection of CMS doesn’t essentially matter for web optimization, particularly since personal options like Wix and Duda are purposely constructed with web optimization in thoughts. Nonetheless, efficiency is vital for issues that matter, corresponding to conversions and the person expertise, and the very fact is that the HTTPArchive Know-how Comparability Report ranks WordPress final for Core Net Vitals efficiency in July.
