The Core Internet Vitals Know-how Report by the open supply HTTPArchive group ranks content material administration methods by how effectively they carry out on Google’s Core Internet Vitals (CWV). The July replace exhibits that each main platform has improved since June, however not all positive factors had been equal. Joomla posted the most important month-over-month improve, whereas Duda ranked first in July with 84.96% of websites passing CWV.
Why Core Internet Vitals Matter
Core Internet Vitals (CWV) are metrics created by Google to measure how briskly, steady, and responsive a web site feels to customers. Web sites that load rapidly and reply easily maintain guests engaged, whereas websites that fall quick frustrate customers and improve bounce charges. For companies and publishers, CWV scores replicate the consumer 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 checks that analyze how websites are constructed and whether or not they observe efficiency greatest practices.
Collectively, these sources present a constant image of how totally different web site platforms carry out on Core Internet Vitals in the actual world.

Duda as soon as once more is the Core Internet Vitals champion, ranked by the proportion of internet sites that has CWV rating.
#1 Duda — 84.96%
#2 Wix — 73.37%
#3 Squarespace — 68.93%

#6 WordPress — 44.34%
Joomla confirmed the quickest development, however it nonetheless ranked fifth in July. Duda led with the best general efficiency.
Why the Numbers Matter
Core Internet Vitals scores translate into actual variations in how customers expertise web sites. Platforms with larger CWV scores provide 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 Internet Vitals champion in July with a rating of 84.96% of internet sites constructed with the Duda platform having CWV rating.
- Joomla had the most important acquire, however nonetheless ranked close to the underside with solely 54.78% of websites exhibiting CWV rating.
- Wix and Squarespace ranked within the second and third locations, exhibiting robust efficiency however each considerably behind Duda by over ten share factors.
- WordPress ranked final, each in July scores and within the month over month charge of enchancment.
Do Content material Administration Methods Matter For Rating?
I’ve seen discussions on-line about whether or not the selection of content material administration system has an affect on rankings. Some individuals 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 info, after all, present that the other is true. WordPress is the slowest of the content material administration methods on this comparability.
The share of websites constructed with Duda that had Core Internet Vitals rating is 84.96%. The share of WordPress websites with CWV rating is 44.34%. Meaning Duda’s share of websites with good CWV scores is about 92% larger than these constructed with WordPress.
One other difficulty with WordPress is that it has a substantial quantity of technical debt, one thing that non-public content material administration methods do not need to battle with to the identical diploma. Technical debt refers back to the accumulation of outdated code and design selections that make it tougher to take care of, replace, or enhance the platform over time. It’s not distinctive to WordPress, however 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, in a position to be prolonged as nearly any form 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 assist.
- Lack of equitable monetary remuneration or stipends for ongoing work.
- Strain to take care of legacy methods and innovate new options results in overwhelming workloads.
Penalties
- Lack of institutional information and skilled contributors.
- Rising technical debt and slowed innovation cycles.
- Risk to WordPress’s long-term ecosystem well being.”
WordPress has not too long ago 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 mission time to handle the problem of technical debt.
The purpose is that if the content material administration system did impact the power to rank, WordPress websites would in all probability battle 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 might be that the selection of CMS doesn’t essentially matter for website positioning, particularly since personal options like Wix and Duda are purposely constructed with website positioning in thoughts. However, efficiency is vital for issues that matter, comparable to conversions and the consumer expertise, and the very fact is that the HTTPArchive Know-how Comparability Report ranks WordPress final for Core Internet Vitals efficiency in July.
