The Core Net Vitals Expertise Report by the open supply HTTPArchive group ranks content material administration programs 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 good points had 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 an internet site feels to customers. Web sites that load shortly and reply easily maintain 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 Knowledge Is Collected
The CWV Expertise Report combines two public datasets:
- Chrome UX Report (CrUX): Knowledge from Chrome customers who decide in to share efficiency statistics as they browse. This displays how actual customers expertise web sites.
- HTTP Archive: Lab-based exams that analyze how websites are constructed and whether or not they comply with efficiency greatest 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 very best general efficiency.
Why the Numbers Matter
Core Net Vitals scores translate into actual variations in how customers expertise web sites. Platforms with larger CWV scores supply sooner, smoother interactions, whereas these on the backside frustrate customers with slower efficiency. Whereas all six platforms within the comparability are bettering 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 a very good CWV rating.
- Joomla had the most important acquire, however nonetheless ranked close to the underside with solely 54.78% of web sites displaying a very good CWV rating.
- Wix and Squarespace ranked within the second and third locations, displaying sturdy efficiency however each considerably behind Duda by over ten proportion factors.
- WordPress ranked final, each in July scores and within the month over month charge of enchancment.
Do Content material Administration Programs 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’s additionally a notion that WordPress is quicker than Wix, Duda, and Squarespace. The information, after all, present that the other is true. WordPress is the slowest of the content material administration programs on this comparability.
The proportion of web sites constructed with Duda that had a very good Core Net Vitals rating is 84.96%. The proportion of WordPress websites with a very good CWV rating is 44.34%. Meaning Duda’s proportion of web sites with good CWV scores is about 92% larger than these constructed with WordPress.
One other challenge with WordPress is that it has a substantial quantity of technical debt, one thing that personal content material administration programs should not have to wrestle with to the identical diploma. Technical debt refers back to the accumulation of outdated code and design choices that make it more durable 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 advanced right into a full CMS, capable of be prolonged as just about any sort of web site.
- Including new options on prime 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 as a consequence of:
- Excessive volunteer calls for with inadequate systemic help.
- Lack of equitable monetary remuneration or stipends for ongoing work.
- Stress to keep up legacy programs and innovate new options results in overwhelming workloads.
Penalties
- Lack of institutional data and skilled contributors.
- Rising 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 offers the venture time to handle the problem of technical debt.
The purpose is that if the content material administration system did impact the flexibility to rank, WordPress websites would in all probability wrestle to rank due to the comparatively poor efficiency scores and the slower tempo of growth when in comparison with non-public content material administration programs 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 might be that the selection of CMS doesn’t essentially matter for website positioning, particularly since non-public options like Wix and Duda are purposely constructed with website positioning in thoughts. However, efficiency is essential for issues that matter, resembling conversions and the person expertise, and the actual fact is that the HTTPArchive Expertise Comparability Report ranks WordPress final for Core Net Vitals efficiency in July.
