Next.js 15 gives developers unprecedented control over technical SEO — if you know how to configure it correctly.
First, master the Metadata API. Instead of adding raw meta tags in head, use exported metadata objects and dynamic generateMetadata functions. This ensures your Open Graph images, canonical tags, and page titles update cleanly across every route.
Second, implement JSON-LD structured data. Search engines and AI answer engines rely on schema markup to understand what your business actually does. Add Organization, WebSite, Service, and FAQPage schemas.
Third, optimize Core Web Vitals. Use next/image with AVIF/WebP formats, load fonts via next/font/local, and inline critical CSS to eliminate layout shifts and reduce LCP to under 1 second.
Finally, maintain dynamic sitemaps with sitemap.ts. Ensure every blog post, product detail, and service page is included in your XML sitemap for instant Google indexing.
