Technical SEO checklist

In one line

A technical SEO checklist covers the crawlability, indexability, speed and structure issues that affect the whole site, not just one page.

The checklist

  • Site is crawlable (robots.txt not blocking key pages)
  • Important pages are indexed (check Search Console coverage)
  • XML sitemap exists and is submitted
  • HTTPS everywhere, no mixed content
  • Fast Core Web Vitals (LCP, INP, CLS) on mobile
  • Mobile-friendly, responsive layout
  • Clean URL structure and logical site architecture
  • Canonical tags handle duplicates
  • Fixed broken links and redirect chains
  • Structured data (schema) valid and error-free

How to use it

Run this quarterly and after any migration. Prioritise anything that blocks crawling or indexing, those cap your entire site's potential, then speed and structure.

Frequently asked
