Technical SEO Checklist

Technical SEO is the foundation. If search engines cannot properly crawl and index your site, nothing else matters.

Crawling & Indexing

• Verify Google can access your pages — Use our Google Index Checker to confirm your key pages are indexed. If they are not, investigate why.
• Check your robots.txt — Make sure you are not accidentally blocking important pages. Use our Robots.txt Generator to create a properly configured file.
• Submit an XML sitemap — Ensure your sitemap is up to date and submitted to Google Search Console. Your sitemap should include all important pages with correct hreflang tags for multilingual sites.
• Fix crawl errors — Check Google Search Console for 404 errors and server errors. Use our HTTP Status Code Checker to verify individual URLs return 200.
• Check redirect chains — Use our Redirect Checker to find and fix redirect chains. Keep chains to maximum 2 hops. Use 301 for permanent moves, generated with our Htaccess Redirect Generator.

Security & HTTPS

• Verify SSL certificate is valid — Use our SSL Certificate Checker to check validity, expiry date, certificate chain, and SANs. Expired certificates destroy traffic instantly.
• Force HTTPS everywhere — All HTTP URLs should 301 redirect to HTTPS. Verify with our Redirect Checker.
• Check for mixed content — HTTPS pages loading HTTP resources trigger browser warnings. Scan pages with our Meta Tags Analyzer.
• Enable HSTS — HTTP Strict Transport Security tells browsers to always use HTTPS.

Performance & Speed

• Test Core Web Vitals — LCP under 2.5s, FID under 200ms, CLS under 0.1. Test with Google PageSpeed Insights.
• Check server response time — Use our Server Status Checker to verify your server responds quickly. TTFB should be under 200ms.
• Verify hosting quality — Use our Hosting Checker to see your provider. Consider upgrading if performance is poor.
• Check server location — Use our Server Location Checker. Host near your target audience or use a CDN.

DNS & Infrastructure

• Verify DNS records — Use our DNS Records Checker to confirm A, MX, TXT (SPF/DKIM), and NS records are correct.
• Check domain IP — Use our Domain to IP tool to verify your domain resolves correctly.
• Confirm www/non-www redirect — One should 301 redirect to the other. Check with our Redirect Checker.

Frequently Asked Questions

How long does SEO take to show results?

Typically 3-6 months for meaningful improvements in competitive niches. Technical fixes (SSL, speed, indexing) can show impact within weeks. Content and link building take longer to compound.

What is the most important item on this checklist?

If we had to pick one: make sure Google can find and index your pages. Use our Google Index Checker. Everything else is pointless if your pages are not in the index.

Do I need to do everything on this list?

No. Start with the technical SEO section — these are the foundations. Then move to on-page optimization. Off-page and content strategy are ongoing long-term efforts. Prioritize based on your biggest gaps.

How often should I run through this checklist?

Full audit: quarterly. Quick checks (indexing, speed, SSL, errors): monthly. After any major site changes: immediately.

Are these free tools enough or do I need paid ones?

For small to medium websites, our free tools cover everything in this checklist. Paid tools like Ahrefs or Semrush add deeper competitor analysis and historical data, but are not required to rank well.
