Technical SEO Checklist for Modern Web Applications

Single-page applications and modern JS frameworks can quietly tank organic visibility if SEO isn't considered from day one. Our technical SEO checklist covers:

• Server-side rendering or static generation for crawlable content
• Structured data (Schema.org) for rich search results
• Core Web Vitals: LCP, INP and CLS benchmarks
• Canonical tags and proper handling of duplicate content
• XML sitemaps and robots.txt configured correctly for staging vs. production

We run this checklist against every website and web app we ship, and periodically re-audit for clients on retainer as search engine guidelines evolve.
