If content is king, technical SEO is the road network of the kingdom. If the roads are broken, even the most valuable content never reaches its destination. Technical SEO is the infrastructure work that lets search engines find, crawl, understand and index your site without friction. Here is the complete checklist to work through.
1. Crawling and indexing
- Is robots.txt configured correctly? Is it accidentally blocking important pages?
- Is an XML sitemap in place, up to date and submitted to Search Console?
- Are unnecessary, thin or duplicate pages marked noindex?
- Are there indexing errors in Google Search Console?
2. Site architecture and URL structure
- Are URLs short, readable and meaningful? (e.g. /blog/seo-guide)
- Is there a logical category/menu hierarchy?
- Can every page be reached within a few clicks?
- Is the internal linking structure strong?
3. Performance (Core Web Vitals)
- Are LCP, INP and CLS within the "good" range?
- Are images optimized and lazy-loaded?
- Are caching and a CDN active?
4. Mobile friendliness
Google now uses "mobile-first indexing" — it evaluates the mobile version of your site. On mobile, buttons must be comfortably tappable, text readable, and no content should be cut off.
5. Security and technical tags
- Is the SSL certificate (HTTPS) active?
- Does every page have a single, meaningful H1?
- Are titles and meta descriptions unique and optimized?
- Are canonical tags correct and solving duplicate-content issues?
- Is structured data (schema) in place?
- Are Open Graph tags ready for social sharing?
6. Broken links and redirects
404 errors annoy both users and Google. Set up proper 301 redirects for moved pages and avoid redirect chains. Run a broken-link scan regularly.
