Imagine walking into a high-end store. The doors open slowly, lights flicker, and the assistant appears only after a minute. You'd likely leave before seeing anything. That's exactly how your client feels when visiting your outdated WordPress site.
Google and Deloitte research is ruthless: every second of delay past 2 seconds drops conversion by 20%. This isn't pocket change. For a store generating $50,000 monthly, a slow site can cost you $10-15,000.
WordPress, burdened with PHP technology (which must "build" the page on every visit) and dozens of plugins, rarely loads under 3 seconds on mobile. Most smartphone users give up after 3 seconds. You lose them forever.
WordPress was created in 2003 as a blogging platform. To turn it into a professional store or corporate site today, you must "glue on" functionality with plugins.
SEO plugin, security plugin, forms plugin, cookies plugin... Each is external code, often written by amateurs. The result? Technical debt. One plugin update can crash your entire site (the infamous "White Screen of Death"). Worse, each plugin adds database queries that choke your server.
In 2026, Google doesn't just evaluate keywords. The foundation is Core Web Vitals – metrics measuring speed, visual stability, and responsiveness. Browsers reward sites that are instantly interactive.
Thanks to Static Site Generation (SSG) in Next.js, your site is ready to read in a fraction of a second, before the user even blinks. Google sees this as "Premium UX" and boosts your position in search results **above** competitors using old CMS systems.
WordPress sites make up over 40% of the internet, making them the most common target for mass hacker attacks. Automated bots scan the web for known plugin vulnerabilities.
The solution I implement – Headless Next.js – eliminates this attack vector completely:
