Technical SEO is the backbone of your search visibility. A beautifully written piece of content on a technically broken site will never reach its ranking potential. Work through this checklist systematically and address every issue you find.
Crawlability and Indexation
1. Verify your robots.txt is not blocking important pages. 2. Submit an up-to-date XML sitemap to Google Search Console. 3. Check for accidental noindex tags on pages that should be indexed. 4. Review the Coverage report in Search Console for crawl errors. 5. Fix 404s with appropriate 301 redirects.
Site Speed and Core Web Vitals
6. Run Lighthouse audits on your most important pages. 7. Enable browser caching and GZIP compression. 8. Compress all images and serve them in WebP or AVIF format. 9. Eliminate render-blocking resources. 10. Use a CDN to reduce latency.
HTTPS and Security
11. Ensure your site serves exclusively over HTTPS. 12. Check that your SSL certificate is valid. 13. Set up HSTS headers. 14. Verify there are no mixed-content warnings.
Structured Data
15. Implement Organisation and WebSite schema on your homepage. 16. Add Article schema to all blog posts. 17. Use Product schema for product pages. 18. Add FAQPage schema to Q&A sections. 19. Validate all structured data with Google's Rich Results Test.
URL Structure
20. Ensure every page has a canonical tag. 21. Keep URLs short, lowercase, and descriptive. 22. Use hyphens not underscores. 23. Avoid unnecessary query strings. 24. Consolidate duplicate content. 25. Set up proper redirects for any moved pages.
Work through this list methodically. Even addressing ten of these twenty-five items can produce a noticeable improvement in crawl efficiency and ranking performance.
