JavaScript frameworks are no longer an SEO risk, provided they are set up properly.
- Rendering — serve fully rendered HTML. In the Next.js App Router pages are server-rendered or static by default; avoid client-only data fetching for content you want indexed.
- Metadata — a unique title and description per page, canonical URLs, and Open Graph and Twitter cards.
- Structured data — JSON-LD for Organization, WebSite, BreadcrumbList, Article, Product and FAQPage where they apply.
- Crawlability — an automatic XML sitemap, a simple robots.txt that never blocks CSS or JavaScript, and no broken links or redirect chains.
- Performance — aim for LCP under 2.5 s and INP under 200 ms on mobile; Core Web Vitals affect rankings and conversions.
- Internal linking — build topic clusters with a pillar page and supporting articles that link to each other.
