Technical SEO Checklist for Next.js Apps in 2025

Pre-Launch Checklist

Unique title + description on every page. Canonical tag on every page. OG and Twitter Card meta. Sitemap submitted to Google Search Console. All images have alt text and are sized explicitly. JSON-LD schema validated. Core Web Vitals passing — PageSpeed 90+. HTTPS enforced. No broken internal links.

Core Web Vitals Quick Tips

LCP under 2.5s: Use next/image with priority on hero images. INP under 200ms: Defer heavy JS, use useTransition for non-urgent updates. CLS under 0.1: Always set explicit width and height on images.

Competently architect intermandated deliverables with client niches and continually build cross-media growth strategies without robust compromises.
