TL;DR
I migrated my own website from WordPress to Next.js and continued developing its content and SEO. Site-wide Google organic clicks increased from 17 to 132 between the first observable and latest complete 28-day Search Console windows. This is an overall before-and-after comparison, not isolated proof of one change.

No marketing fluff. A practical migration note from my own move away from plugin-heavy WordPress. The page focuses on method, measurement and SEO-safe architecture, not unsupported multipliers.

The checkpoints
The technical rows describe the migration method. The GSC row is a measured site-wide result from final Web search data without dimensions; its source, date ranges and limitations are recorded in the proof ledger.
| Metric | WordPress (before) | Next.js (after) | Improvement |
|---|---|---|---|
LCP Largest Contentful Paint | plugin-heavy WordPress | Next.js + edge CDN | faster first view |
INP Interaction to Next Paint | plugin JS bundles | less client JS | smoother interactions |
CLS Cumulative Layout Shift | theme/layout shifts | stable components | more stable UI |
SEO Technical SEO | plugin-dependent | structured metadata | cleaner crawlability |
GSC Google organic clicks · 28 days | 17 · 23 Apr–20 May 2025 | 132 · 10 Jul–6 Aug 2026 | +676.5% clicks |
Interpretation: 17 → 132 clicks equals +676.5%, but the baseline was very small. The comparison covers the entire site and a broader query mix; it does not prove that the migration alone caused the increase, and Search Console clicks are not leads or revenue.
Why I made the switch
Why was WordPress holding us back?
My previous WordPress setup depended on a theme and several plugins for the portfolio, blog, forms, SEO and security. That made updates and performance diagnosis harder because the page combined database work with assets from several independent components.
Why Next.js specifically?
Next.js renders pages on the server and ships pre-built HTML. No database call per page view. Static and dynamic content is cached at the edge via CDN. React Server Components mean less JavaScript reaches the browser and performance can be measured per route.
Why can conversions improve after migration?
Conversion rate is bounded by friction: slow pages, layout shifts, unclear forms and heavy client-side JavaScript all reduce trust. The migration removed plugin risk, simplified the lead path and made performance measurable before and after launch.
Can my business expect the same results?
It depends on your starting point. If your current site is slow, unstable or plugin-heavy, a migration can create measurable upside. The first step is a benchmark of Core Web Vitals, analytics and search visibility before I quote.
WordPress vs Next.js – feature comparison
| Aspect | WordPress | Next.js |
|---|---|---|
| Architecture | PHP + MySQL, monolithic | React server-rendered, edge CDN |
| Dependencies | Theme and plugins by feature | Framework and packages reviewed in code |
| Security updates | Core, theme and plugins updated separately | Framework and dependencies updated together |
| Performance | Depends on theme, plugins, hosting and cache | Depends on implementation, cache and CDN |
| SEO baseline | Often configured through a plugin | Metadata and structured data in the application |
| Hosting | PHP/database hosting | Node or edge hosting |
| Maintenance | CMS, theme and plugin compatibility | Code, framework and dependency compatibility |
| Customization | Bound by theme and plugin architecture | Bound by the product scope and codebase |
