Next.js Development

Next.js sends fully rendered HTML from the server, so crawlers read your content on the first request. A plain React app sends an empty shell and fills it in with JavaScript. Google will usually render that eventually, but AI crawlers such as ChatGPT, Perplexity and ClaudeBot do not execute JavaScript at all, so client-only pages are invisible to them.

They differ in when the HTML is generated. SSG builds pages at deploy time and is fastest for content that rarely changes. SSR builds on each request and suits personalised or fast-moving data. ISR builds statically then refreshes on a timer, which fits blogs and catalogues that update daily but must stay fast.

Yes. Static and incrementally regenerated pages are served from a CDN edge, so traffic spikes hit cached HTML rather than your origin. We combine that with route-level caching, image optimisation and database connection pooling. The architecture scales to millions of monthly visits without a proportional server bill.

Cost tracks scope, not framework. A marketing site with 10 to 15 pages and a CMS sits at the lower end; a Next.js application with authentication, dashboards, payments and an admin panel is a multiple of that. We quote against a fixed scope after discovery so the number does not move mid-build.

Yes, and we do it without losing rankings. We map every existing URL to its new route, set 301 redirects for anything that changes, carry over metadata and structured data, and keep the sitemap accurate through the switch. Traffic is monitored for several weeks after launch to catch regressions early.
