Use getStaticProps with ISR in Next.js by returning a revalidate property alongside props, enabling incremental static regeneration to serve pre-rendered pages that update periodically without full rebuilds.

Use getServerSideProps in Next.js only when your page requires real-time data on every request, as it bypasses static generation and ISR, potentially impacting performance compared to pre-rendered pages.

Add SEO meta tags in Next.js by importing the Head component into your Pages Router files, then defining titles, descriptions, and Open Graph tags directly within the page's JSX structure for optimal search engine indexing.

Optimize Next.js images using the built-in next/image component, and implement lazy loading for secondary components to reduce initial bundle size, directly improving frontend performance and SEO metrics.

Configure Next.js internationalization by setting up locale-specific routing patterns within the Pages Router directory structure, managing translations to serve localized content based on user locale preferences.

Create custom 404 error pages in Next.js by adding a 404.js file directly inside the pages directory, allowing you to handle routing errors and implement Error Boundaries for a customized fallback experience.
