Tutorials — Build a Fast, SEO-Friendly Next.js Site

Step-by-step guides to set up a Next.js project with TypeScript, dark mobile-first styling, metadata, JSON-LD, robots, sitemap, security headers, and a custom 404 page. Each tutorial is written for crawlability and clarity.

• Next.js project setup

  Create a new Next.js app with TypeScript, App Router, and install SEO and UI helpers like next-sitemap, lucide-react, and clsx.

• SEO metadata & JSON-LD

  Configure metadata, OpenGraph, Twitter cards, canonical URLs, and structured data (JSON-LD) for better search visibility.

• Dark, mobile-first global CSS

  Add a dark theme with CSS variables, responsive layout, sticky nav, cards, and mobile-first breakpoints.

• Robots.txt and sitemap

  Use Next.js route handlers to generate robots.txt and a dynamic sitemap.xml for crawlers.

• Performance and security headers

  Set security and performance headers in next.config (X-Content-Type-Options, X-Frame-Options, Referrer-Policy, etc.).

• PWA manifest and 404 page

  Add a web app manifest for installability and a custom 404 not-found page for better UX.
