For most of the 2010s, WordPress was the default choice for business websites. It's still a capable platform for the right use case. But for businesses with serious performance, security, and integration requirements, Next.js has become the clear technical winner.
Performance: Not Even Close
Google's Core Web Vitals are now a direct ranking factor. WordPress sites — even heavily optimised ones — consistently score 70–85 on Lighthouse. Next.js sites regularly score 95–100.
The difference: Next.js uses server-side rendering, static site generation, and edge caching by default. Pages load in under 1 second. Images are optimised automatically. Code is split so visitors only download what they need.
Security: A Fundamental Difference
WordPress's popularity makes it a constant target. Over 90% of hacked websites run WordPress. Plugin vulnerabilities, database exposures, and brute-force attacks are endemic.
Next.js with a modern deployment (Vercel, Netlify) has no database to expose, no plugin ecosystem to maintain, and no admin login to brute-force. The attack surface is dramatically smaller.
Integration Capabilities
Enterprise businesses need their website to connect to CRMs, ERPs, analytics platforms, and custom APIs. WordPress achieves this through plugins of varying quality. Next.js achieves this through typed API routes and server actions — clean, maintainable, testable code.
The Migration Question
Migrating from WordPress to Next.js is a 6–10 week project for most businesses. The content migration, design redesign, and SEO preservation work is straightforward with the right team. The performance and security gains make it worthwhile for any business with genuine traffic and lead generation requirements.
