Technical SEO Checklist: 50+ Points to Audit

Technical SEO forms the foundation of any successful search strategy. Without proper technical implementation, even the best content won't reach its potential. This comprehensive checklist covers everything you need to audit.

Crawlability & Indexation

Robots.txt Configuration

Your robots.txt file is the first thing search engine crawlers encounter. Ensure it's properly configured:

  • βœ…File is accessible at /robots.txt
  • βœ…No critical pages are blocked
  • βœ…Sitemap location is specified
  • βœ…Different rules for different bots if needed
User-agent: *

Disallow: /admin/

Disallow: /private/

Allow: /

Sitemap: https://yoursite.com/sitemap.xml

XML Sitemap Best Practices

  • βœ…Sitemap is auto-generated and up-to-date
  • βœ…Only includes canonical, indexable URLs
  • βœ…Submitted to Google Search Console
  • βœ…Split into multiple sitemaps if over 50,000 URLs

Site Architecture

A well-structured site helps both users and search engines navigate your content efficiently.

URL Structure

Internal Linking Strategy

  • Hub Pages: Create comprehensive pillar content that links to related articles
  • Contextual Links: Link naturally within content to relevant pages
  • Navigation: Ensure critical pages are within 3 clicks of the homepage
  • Breadcrumbs: Implement for both users and search engines
  • Performance Optimization

    Core Web Vitals Checklist

    Largest Contentful Paint (LCP)
    • βœ…Optimize and compress images
    • βœ…Use next-gen formats (WebP, AVIF)
    • βœ…Implement lazy loading below the fold

    Mobile Optimization

    With mobile-first indexing, mobile optimization is non-negotiable:

    • βœ…Touch targets at least 48x48 pixels
    • βœ…Readable font sizes (minimum 16px)
    • βœ…No horizontal scrolling required

    Schema Markup

    "@context": "https://schema.org",

    "@type": "Article",

    "headline": "Your Article Title",

    "author": {

    "@type": "Person",

    "name": "Author Name"

    },

    "datePublished": "2025-01-10",

    "image": "https://example.com/image.jpg"

    }

    Essential Schema Types

    • Organization
    • LocalBusiness (if applicable)
    • Article/BlogPosting
    • Product (for e-commerce)
    • FAQ
    • HowTo
    • BreadcrumbList

    Security & HTTPS

    • βœ…Valid SSL certificate
    • βœ…All resources loaded over HTTPS
    • βœ…HTTP to HTTPS redirects in place
