·1,543 views·By Richard Cohen

What Is Technical SEO?

Technical SEO ensures Google can crawl, index, and understand your site. Without it, even the best content won't rank.

The Technical SEO Checklist

Crawlability

  • robots.txt: correctly configured, not accidentally blocking important pages
  • No redirect chains: keep to max 1 redirect per URL
  • No broken links: fix all 4xx errors
  • Crawl budget: important for large sites (1,000+ pages)
  • Indexation

    XML Sitemap: submit to Google Search Console. Include only canonical, published pages. Exclude thin content, paginated pages, filtered URLs.

    Canonical tags: prevent duplicate content issues with ``.

    Page Speed

    Target: LCP < 2.5s on mobile.

  • Images: WebP format + lazy loading
  • CSS/JS: minify and defer non-critical
  • CDN: Cloudflare, Vercel Edge
  • Remove render-blocking resources
  • Site Architecture

    3-click rule: every page reachable in ≤ 3 clicks from homepage. Build topical silos for better crawl efficiency.

    HTTPS

    HTTPS has been a ranking signal since 2014. Ensure your SSL certificate is valid and properly configured.

    Mobile-First

    Google uses mobile-first indexing. Test with Mobile-Friendly Test.
