This guide provides a comprehensive technical SEO checklist to help you enhance your website’s performance.
1. Website Crawling and Indexing
1.1 Check Robots.txt File
Ensure your robots.txt file is correctly configured to allow search engines to crawl important pages.
Use Disallow directives only for pages you don’t want indexed.
1.2 Optimize XML Sitemap
Submit an updated XML sitemap to Google Search Console and Bing Webmaster Tools.
Ensure all indexed pages are included and exclude irrelevant or duplicate pages.
1.3 Fix Indexing Issues
Use Google Search Console’s Coverage Report to identify pages blocked from indexing.
Implement proper canonical tags to avoid duplicate content issues.
2. Site Speed and Performance Optimization

Use Google PageSpeed Insights or GTmetrix to analyze page speed.
Optimize images using modern formats (WebP, AVIF) and compression tools.
Enable lazy loading for images and videos.
2.2 Minimize HTTP Requests
Reduce unnecessary scripts, CSS, and images.
Combine multiple CSS and JavaScript files where possible.
2.3 Implement a Content Delivery Network (CDN)
Use a CDN to serve static files from the nearest server to users.
Popular options include Cloudflare, Akamai, and Amazon CloudFront.
2.4 Enable Browser Caching
Set caching policies for static files to reduce load times for repeat visitors.
3. Mobile-Friendliness

Reduce Cumulative Layout Shift (CLS) by ensuring elements don’t shift unexpectedly.
Enhance First Input Delay (FID) by optimizing JavaScript execution.
4. Secure Your Website
4.1 Install SSL Certificate (HTTPS)
Ensure your website uses HTTPS for security and trust.
Redirect all HTTP URLs to HTTPS to avoid duplicate content issues.
4.2 Protect Against Mixed Content Issues
Ensure all images, scripts, and resources load over HTTPS.
