As the digital landscape continues to evolve, the importance of conducting regular technical SEO audits cannot be overstated. In this article, we’ll take you through a comprehensive checklist to help you identify and fix common technical SEO issues that might be hindering your website’s performance.

Step 1: Crawlability Audit

• Check crawlability: Ensure that search engines can crawl your website by checking for any crawl errors. Use tools like Screaming Frog, Ahrefs, or Google Search Console to identify any crawl-related issues.
• Verify sitemap: Make sure you have a valid sitemap submitted to Google Webmaster Tools and Bing Webmaster Tools. Update it regularly to reflect changes in your website’s structure.
• Check robots.txt: Ensure that your robots.txt file is not blocking important pages or directories from being crawled.

Step 2: Mobile-Friendliness Audit

• Verify mobile-friendliness: Use tools like Google’s Mobile-Friendly Test or GTmetrix to check if your website is mobile-friendly.
• Check page speed on mobile: Ensure that your website loads quickly and is usable on mobile devices. Aim for a score of 70+ on the PageSpeed Insights tool.

Step 3: Page Speed Audit

• Verify page load time: Check your page load time using tools like GTmetrix, Pingdom, or Google’s PageSpeed Insights.
• Optimize images: Compress images to reduce file size and improve page load times. Use tools like TinyPNG or ShortPixel for image compression.
• Minify code: Minify JavaScript, CSS, and HTML code to reduce file sizes and improve page load times.

Step 4: SSL Audit

• Verify SSL installation: Check if your website has a valid SSL certificate installed (HTTPS).
• Check SSL configuration: Ensure that your SSL certificate is properly configured and not causing any issues with crawling or indexing.
• Test SSL validation: Use tools like SSL Labs or Qualys SSL to test your SSL certificate’s validity and configuration.

Step 5: XML Sitemap Audit

• Verify sitemap format: Check if your sitemap follows the correct format (XML) and is not causing any issues with crawling.
• Check sitemap size: Ensure that your sitemap is not too large, as this can cause issues with crawling and indexing.
• Test sitemap submission: Verify that your sitemap has been successfully submitted to Google Webmaster Tools and Bing Webmaster Tools.

Step 6: Internal Linking Audit

• Verify internal linking structure: Check if your website’s internal linking structure is logical, easy to navigate, and not causing any issues with crawling or indexing.
• Check anchor text variation: Ensure that you’re using a variety of anchor texts for internal linking to avoid over-optimization.

Step 7: Broken Link Audit

• Identify broken links: Use tools like Screaming Frog or Ahrefs to identify broken links on your website.
• Verify link fix: Fix any broken links by updating or removing them from your website.

Step 8: Structured Data Audit

• Verify structured data presence: Check if your website is using structured data (e.g., JSON-LD, schema.org) to provide search engines with additional context.
• Check structured data syntax: Ensure that your structured data follows the correct syntax and formatting.

Step 9: Canonicalization Audit

• Verify canonical URLs: Check if your website has a valid canonical URL set for each page (e.g., using the rel="canonical" attribute).
• Test canonical URL linking: Verify that your canonical URLs are correctly linked to other pages on your website.

Step 10: Robots.txt Audit

• Verify robots.txt file presence: Check if your website has a valid robots.txt file.
• Check robots.txt syntax: Ensure that your robots.txt file follows the correct syntax and formatting.
