2025 Core Web Vitals Challenge: WordPress Versus Everyone via @sejournal, @martinibuster

The Core Web Vitals Technology Report shows the top-ranked content management systems by Core Web Vitals (CWV) for the month of June (July’s statistics aren’t out yet). The breakout star this year is an e-commerce platform, which is notable because shopping sites generally have poor performance due to the heavy JavaScript and image loads necessary to provide shopping features.

This comparison also looks at the Interaction to Next Paint (INP) scores because they don’t mirror the CWV scores. INP measures how quickly a website responds visually after a user interacts with it. The phrase “next paint” refers to the moment the browser visually updates the page in response to a user’s interaction.

A poor INP score can mean that users will be frustrated with the site because it’s perceived as unresponsive. A good INP score correlates with a better user experience because of how quickly the website performs.

Core Web Vitals Technology Report

The HTTP Archive Technology Report combines two public datasets:

  1. Chrome UX Report (CrUX)
  2. HTTP Archive

1. Chrome UX Report (CrUX)
CrUX obtains its data from Chrome users who opt into providing usage statistics reporting as they browse over 8 million websites. This data includes performance on Core Web Vitals metrics and is aggregated into monthly datasets.

2. HTTP Archive
HTTP Archive obtains its data from lab tests by tools like WebPageTest and Lighthouse that analyze how pages are built and whether they follow performance best practices. Together, these datasets show how websites perform and what technologies they use.

The CWV Technology Report combines data from HTTP Archive (which tracks websites through lab-based crawling and testing) and CrUX (which collects real-user performance data from Chrome users), and that’s where the Core Web Vitals performance data of content management systems comes from.

#1 Ranked Core Web Vitals (CWV) Performer

The top-performing content management system is Duda. A remarkable 83.63% of websites on the Duda platform received a good CWV score. Duda has consistently ranked #1, and this month continues that trend.

For Interaction to Next Paint scores, Duda ranks in the second position.

#2 Ranked CWV CMS: Shopify

The next position is occupied by Shopify. 75.22% of Shopify websites received a good CWV score.

This is extraordinary because shopping sites are typically burdened with excessive JavaScript to power features like product filters, sliders, image effects, and other tools that shoppers rely on to make their choices. Shopify, however, appears to have largely solved those issues and is outperforming other platforms, like Wix and WordPress.

In terms of INP, Shopify is ranked #3, at the upper end of the rankings.

#3 Ranked CMS For CWV: Wix

Wix comes in third place, just behind Shopify. 70.76% of Wix websites received a good CWV score. In terms of INP scores, 86.82% of Wix sites received a good INP score. That puts them in fourth place for INP.

#4 Ranked CMS: Squarespace

67.66% of Squarespace sites had a good CWV score, putting them in fourth place for CWV, just a few percentage points behind the No. 3 ranked Wix.

That said, Squarespace ranks No. 1 for INP, with a total of 95.85% of Squarespace sites achieving a good INP score. That’s a big deal because INP is a strong indicator of a good user experience.

#5 Ranked CMS: Drupal

59.07% of sites on the Drupal platform had a good CWV score. That’s more than half of sites, considerably lower than Duda’s 83.63% score but higher than WordPress’s score.

But when it comes to the INP score, Drupal ranks last, with only 85.5% of sites scoring a good INP score.

#6 Ranked CMS: WordPress

Only 43.44% of WordPress sites had a good CWV score. That’s over fifteen percentage points lower than fifth-ranked Drupal. So WordPress isn’t just last in terms of CWV performance; it’s last by a wide margin.

WordPress performance hasn’t been getting better this year either. It started 2025 at 42.58%, then went up a few points in April to 44.93%, then fell back to 43.44%, finishing June at less than one percentage point higher than where it started the year.

WordPress is in fifth place for INP scores, with 85.89% of WordPress sites achieving a good INP score, just 0.39 points above Drupal, which is in last place.

But that’s not the whole story about the WordPress INP scores. WordPress started the year with a score of 86.05% and ended June with a slightly lower score.

INP Rankings By CMS

Here are the rankings for INP, with the percentage of sites exhibiting a good INP score next to the CMS name:

  1. Squarespace 95.85%
  2. Duda 93.35%
  3. Shopify 89.07%
  4. Wix 86.82%
  5. WordPress 85.89%
  6. Drupal 85.5%

As you can see, positions 3–6 are all bunched together in the eighty percent range, with only a 3.57 percentage point difference between the last-placed Drupal and the third-ranked Shopify. So, clearly, all the content management systems deserve a trophy for INP scores. Those are decent scores, especially for Shopify, which earned a second-place ranking for CWV and third place for INP.

Takeaways

How To Create a Certified Fast Website To Compete In 2025

This post was sponsored by Bluehost. The opinions expressed in this article are the sponsor’s own.

Imagine clicking on a website only to wait several seconds for it to load.

Frustrating, right?

Your prospective customers think so, too.

In a world where attention spans are shrinking, even a one-second delay can lead to lost visitors, lower rankings, and missed revenue opportunities.

Research finds that B2C websites that load in one second or less have conversion rates three times higher than those that load in five seconds or more.

Conversion rates are 2.5 times higher for B2C websites that load in one second or less.

In other words, speed is no longer a luxury.

Speed is a necessity.

A fast-loading website enhances user experience, boosts SEO rankings, and drives higher conversions.

And with search engines and consumer expectations continuing to evolve, businesses must prioritize performance to stay ahead of the competition.

Implementing the right strategies ensures that websites remain fast, competitive, and ready for the demands of 2025.

A trusted partner like Bluehost provides the robust infrastructure, advanced caching mechanisms, and built-in performance enhancements needed to help websites reach peak efficiency.

1. How To Select The Right Hosting Plan

A website’s performance starts with selecting the right hosting plan. The plan should align with the site’s current and future needs to effectively accommodate growth and traffic fluctuations.

Assess Your Website’s Needs

Before settling on a hosting plan, it’s crucial to evaluate key factors like traffic expectations, content types, and scalability.

For example, websites with heavy multimedia content require more resources than text-based sites, and anticipated visitor numbers influence server capacity needs.

Additionally, selecting a plan that supports future growth ensures smooth scaling without performance bottlenecks.

Match Your Website’s Needs To What The Host Provides

Different hosting solutions cater to different website requirements, ranging from budget-friendly shared hosting to more robust, performance-driven plans. Bluehost offers multiple hosting options tailored to various business needs.

Shared Hosting can work well for smaller websites with moderate traffic, offering a cost-effective way to get started.

Bluehost’s VPS hosting offers more power and flexibility by providing dedicated resources, making it an excellent choice for growing websites that need additional performance.

For large-scale websites demanding maximum speed and control, our dedicated hosting plans deliver exclusive server access with top-tier performance for optimal speed and scalability.

2. Implement Caching Mechanisms

Caching is an essential tool for optimizing website speed by reducing the need to load the same data repeatedly. By storing frequently accessed files, caching decreases server load, enhances response times, and ensures visitors experience faster page loads.

Websites that effectively utilize caching experience better performance, lower bounce rates, and improved search rankings.

Use Built-In Caching Features

For instance, Bluehost provides multiple caching mechanisms to enhance website performance, such as PHP APC (Alternative PHP Cache). A powerful opcode caching system, PHP APC improves database query speed and optimizes PHP script execution, ensuring that frequently accessed data is retrieved faster.

On the other hand, edge caching minimizes latency by delivering content from servers closest to the user, reducing server response times and improving load speeds.

Bluehost makes it easy to use caching to enhance website speed. Caching can be enabled directly through the Bluehost control panel, ensuring seamless implementation.

Additionally, Bluehost is powered by Dell rack-mount servers, which use AMD EPYC chips, DDR5 RAM, and ultrafast NVMe storage. With caching plugins like W3 Total Cache or WP Rocket, your web pages will load faster, improving the user experience, SEO, traffic, and conversion rates.

3. Absolutely Leverage Content Delivery Networks (CDNs)

Another way to speed up websites is to examine how content is delivered to users. A Content Delivery Network (CDN) enhances website performance by distributing content across multiple servers worldwide. This reduces latency and ensures visitors load pages faster, regardless of location.

CDNs minimize the physical distance between the server and the user by caching static assets like images, stylesheets, and scripts at various data centers worldwide. This results in load times and reduced bandwidth usage.

Beyond speed improvements, CDNs also enhance website security by protecting against DDoS attacks, traffic spikes, and malicious bots. Some CDNs offer additional features, such as image optimization, automated compression, and firewall rules, that further improve performance and security.

CDNs & Bluehost

Bluehost offers built-in CDN solutions, including Cloudflare integration, to help websites achieve optimal performance and security.

Activating a CDN through Bluehost’s dashboard is straightforward, and configuring settings that best suit a website’s needs significantly improves speed and reliability.

4. Optimize Images & Media

Impact of Media Files on Load Times

Large images and unoptimized videos can significantly slow down a website. Why? High-resolution media files require more bandwidth and processing power, leading to slower page loads and a poorer user experience.

This is particularly problematic for mobile users and those with slower internet connections since heavy media files can take significantly longer to load, frustrating visitors and increasing bounce rates.

Additionally, media files that are not optimized can consume excessive server resources, potentially affecting overall website performance. If too many large files are loaded simultaneously, the hosting environment can strain, causing slowdowns for all users.

Image- and media-based slowdowns are widespread on websites that rely heavily on visual content, such as e-commerce platforms, portfolios, and media-heavy blogs.

Reducing file sizes, choosing appropriate formats, and leveraging compression techniques can greatly enhance website speed while maintaining visual quality.

How To Size Images The Right Way

First, while it may be common and easy to do, avoid using the width and height attributes in HTML to resize images since this forces the browser to scale the image, increasing load times and decreasing performance.

Instead, resize images before uploading them using graphic editing tools such as Photoshop, GIMP, or online compression services. Scaling images improperly can lead to pixelation and a stretched appearance, negatively impacting user experience.

By resizing images to their intended display size before uploading, websites can significantly reduce the amount of data a browser needs to process, resulting in faster page loads and a more visually appealing layout.

Appropriately resized images will also have a higher visual quality because they are sized for the right display dimensions.

How To Compress Images For Better Website Performance

Compressing images using tools like Squoosh, TinyPNG, or plugins like Smush helps reduce file sizes without sacrificing quality.

Implementing lazy loading ensures that off-screen images and videos only load when needed, reducing initial load times and enhancing overall site performance.

5. Minimize Plugins & External Scripts

How To Discover Your Plugins’ Usage

Overloading a website with excessive plugins and external scripts can severely impact performance. Therefore, it’s essential to regularly assess installed plugins and remove outdated, redundant, or unnecessary ones.

Limiting the number of external scripts running on a page can also help reduce loading times and improve efficiency.

How To Choose Efficient Plugins

Selecting the right plugins is crucial for maintaining website performance. First, look for lightweight, well-coded plugins that prioritize speed and efficiency.

Then, regularly auditing your plugins and removing outdated or redundant ones can prevent conflicts and minimize resource usage.

Bluehost provides hosting environments tailored for WordPress users, ensuring compatibility with essential caching, security, and SEO plugins.

By hosting your website on a reliable platform like Bluehost, you can benefit from a stable infrastructure that complements the best WordPress plugins. This will help you enhance functionality without compromising speed.

6. Tips For Compression, Minification & Technical Tweaks

Additional technical optimizations, in addition to caching and CDNs, can further improve site speed and performance. Compression and minification techniques help reduce file sizes, while other backend optimizations ensure web pages load efficiently.

Implementing these strategies can significantly improve desktop and mobile user experiences.

Benefits Of Compression

Reducing the size of HTML, CSS, and JavaScript files significantly improves page speed. Compressed files require less bandwidth and load faster, creating a smoother user experience.

Effortless Compression & Technical Optimization With Bluehost

Bluehost makes compression easy. GZIP compression can be enabled via Bluehost’s control panel or by modifying the .htaccess file.

Plugins like Autoptimize help minify code by removing unnecessary characters, ensuring that files remain lightweight and optimized for performance.

Utilizing ETags & Expires Headers

Another important aspect of page speed optimization involves using ETags and expired headers, which help streamline browser requests and improve overall efficiency.

These settings instruct a visitor’s browser on how to handle cached content, preventing unnecessary reloads and reducing the number of requests made to the server.

ETags (Entity Tags) are used by browsers to determine whether cached resources have been modified since the last visit. If the content remains unchanged, the browser loads the local copy instead of downloading it again, minimizing bandwidth usage and speeding up load times.

On the other hand, expired headers specify a timeframe for when specific resources should be refreshed.

By setting an appropriate expiration date for static files like images, CSS, and JavaScript, web developers can ensure that repeat visitors are not unnecessarily reloading content that has not changed.

For example, a website logo that remains consistent across pages can be cached efficiently so that users do not have to download it every time they navigate the site.

Properly configuring these settings enhances website performance, particularly for sites with recurring visitors. It prevents redundant data transfers and reduces the workload on the browser and server.

Many hosting providers, including Bluehost, offer tools and support to help website owners implement these optimizations effectively. This ensures a faster and more seamless user experience.

7. Regularly Monitor & Execute Maintenance

Practice Continuous Performance Assessment

Technology changes and slows down. Websites are no exception.

Therefore, websites should undergo regular performance assessments to ensure they’re continually optimized for the best user experience.

Routine speed testing helps identify areas where performance can be improved, whether by addressing slow-loading elements, optimizing server response times, or refining backend processes.

Various tools can assist in performance evaluation. Google PageSpeed Insights, for example, provides detailed reports on website speed and offers specific recommendations for improvements.

Lighthouse, a Google open-source tool, analyzes performance, accessibility, and SEO, helping site owners fine-tune their pages.

Beyond automated tools, ongoing monitoring through website analytics platforms, such as Google Analytics, can offer valuable insights into user behavior.

High bounce rates and low engagement metrics may indicate slow performance, guiding further refinements.

Businesses running ecommerce platforms or large applications should consider integrating application performance monitoring (APM) tools to track performance bottlenecks in real time.

Maintenance Tips

Regular updates to website software, regardless of the platform used, are essential for security and performance.

Content management systems (CMS) like WordPress, Joomla, and Drupal require frequent updates to core files, themes, and plugins to prevent compatibility issues and vulnerabilities. Similarly, frameworks and libraries for custom-built sites must be kept up to date to ensure efficiency and security.

Database optimization is another crucial maintenance task. Over time, databases accumulate redundant data, slowing down query execution.

Periodic optimizations, such as removing unused tables, cleaning up post revisions, and properly indexing databases, can enhance efficiency.

Server maintenance is equally important. Websites hosted on dedicated or VPS servers should have automated backups, uptime monitoring, and log analysis configured.

Cloud-based hosting solutions like Bluehost Cloud provide performance-tracking tools that can help identify and mitigate slowdowns at the infrastructure level, a 100% uptime SLA, and more to ensure websites run smoothly.

Lastly, implementing a proactive security strategy ensures ongoing performance stability. Regular malware scans, security patches, and SSL certificate renewals help prevent vulnerabilities that could slow down or compromise a website.

Security plugins and firewalls, such as Cloudflare, add an extra layer of protection while minimizing unwanted traffic that could strain server resources.
