The 18-Step SEO Audit Checklist

 The performance of your website in search engine results depends heavily on conducting an appropriate SEO audit. Your website visibility and traffic growth together with improved rankings become possible after you solve identified problems.



The following guide presents an 18-step SEO audit checklist which will help you rate and optimize your website successfully.

Step 1: Check for Indexing Issues

Ensure your website is indexed by search engines. Use the following tools to check:

  • Google Search Console: Navigate to the Indexing section to see the indexed pages.
  • Site Command: Search site:yourwebsite.com on Google to check how many pages are indexed.

Fix: If pages are missing, check for crawl errors, sitemap issues, or improper use of noindex tags.


Step 2: Analyze Page Load Speed


Poor website speed generates negative effects on user interaction and search engine rankings. Use tools like:


Google PageSpeed Insights

GTmetrix

Lighthouse

You should compress images while enabling cache functions and minimizing CSS and JavaScript code along with implementing a CDN for accelerated delivery.

Step 3: Ensure Mobile-Friendliness


Having a mobile-friendly website becomes indispensable because Google directs its primary indexing efforts to mobile platforms. The compatibility of your website can be checked with the aid of the Mobile-Friendly Test tool.
