WordPress still powers 43% of websites on the web. It's a mature technology with a massive ecosystem. But for a business that wants to stand out and perform, is it still the right choice in 2025?
The real advantages of WordPress
- —Huge ecosystem, thousands of plugins for almost everything.
- —Easy to use for managing content once set up.
- —Often lower upfront cost than custom development.
- —Many developers know the platform, making it easy to find help.
- —Gutenberg block editor has significantly improved the content editing experience.
The limitations nobody mentions
WordPress was built in 2003 as a blogging tool. Its monolithic architecture is fundamentally different from modern frameworks. As a result, WordPress sites are on average 3 to 5 times slower than an equivalent Next.js site, even with caching plugins.
Security is the other major issue. WordPress is the number one target for automated attacks on the web, 90% of hacked CMS sites run WordPress. Not because WordPress is poorly built, but because its market share makes it a massive target. Every plugin you install is an additional attack surface.
- —Performance, Core Web Vitals are often in the red without significant optimisation work.
- —Security, constant updates required, vulnerable plugins are common.
- —Design, impossible to truly move away from a template without recoding everything.
- —Technical debt, WordPress sites accumulate debt over time (outdated plugins, conflicts).
- —Plugin dependency, a plugin abandoned by its maintainer can break your site overnight.
The benchmarks that make you think
In our comparative tests on equivalent projects, a well-optimised WordPress site (with WP Rocket, Imagify, CDN) shows an average LCP (Largest Contentful Paint) of 2.8 seconds. The same site built in Next.js with Server Components and deployed on the Vercel Edge Network: 0.6 seconds. That's a 4.5x difference.
Google has used Core Web Vitals as a ranking signal since 2021. An LCP above 2.5 seconds is rated "Poor" by Google. Below 1.2 seconds is "Good". On competitive keywords, this technical difference can represent several positions in search results, positions that translate directly into traffic and revenue.
Total cost of ownership over 3 years
The "WordPress is cheaper" argument often falls apart over time. Factor in: regular updates that sometimes need a developer, plugin conflicts to resolve, redesigns needed because a theme is no longer maintained, and security incidents that can be expensive to manage.
An average WordPress site costs between €150 and €400/month in maintenance when managed by an agency. Over 3 years, that's €5,400–€14,400 in recurring costs, on top of the initial development. A well-architected Next.js site, by contrast, can run on €80–€150/month for hosting and light maintenance.
The SEO impact
WordPress has long been perceived as "good for SEO" thanks to Yoast. In reality, Yoast handles on-page SEO (meta tags, sitemaps, breadcrumbs), exactly what any modern framework does natively. The real SEO factor in 2025 is technical performance, and that's where WordPress is structurally disadvantaged.
A Next.js site using Static Site Generation sends pre-rendered HTML to the browser within milliseconds. Google's bots index content instantly, without waiting for JavaScript execution. On WordPress, even with a cache plugin, rendering is done server-side on the fly, which is intrinsically slower and less predictable.
Next.js explained simply
Next.js is the React framework used by Vercel, GitHub, TikTok and hundreds of thousands of startups. It generates ultra-fast static pages while retaining the flexibility of JavaScript for dynamic parts. It's the best of both worlds: the speed of a static site and the power of a modern application.
Concretely for you: your site is compiled in advance into optimised HTML, CSS and JavaScript files, distributed via a global CDN. When a user visits from Brussels or Luxembourg, they receive the file from the nearest server, typically under 50ms of network latency.
When WordPress is still a good choice
For a personal blog, an association website, or a small business that needs a site quickly and cheaply, WordPress is perfectly adequate. If your site is primarily an information platform and performance isn't critical, it's a valid option. Similarly, if your team has WordPress expertise and needs immediate editorial autonomy, that's a legitimate factor.
When to go custom
As soon as your site becomes a business tool, lead generator, e-commerce platform, premium brand showcase, WordPress becomes a constraint. Performance, design flexibility and security then justify a custom build.
A telling sign: if you've installed more than 20 plugins on your current WordPress site, it's probably slow, hard to maintain, and vulnerable. That's the moment to consider migrating to a modern stack.
Migration: how does it work?
Moving from WordPress to Next.js is a structured process, not a complete rebuild from zero. We export your existing content, reimport it into a headless CMS (Sanity or Contentful depending on your needs), and redesign the interface. Content is preserved, and SEO is carefully maintained through 301 redirects.
At WCS, we build on Next.js, the React framework used by major global brands. The results are incomparable: sub-1-second load times, Lighthouse score 95+, and total design freedom without the constraints of a theme.
