How to Conduct a Full Https Migration Audit Before Going Live

by

Switching your website from HTTP to HTTPS is a crucial step in ensuring security and trust for your visitors. Before going live with your HTTPS migration, conducting a thorough audit is essential to prevent issues that could affect your site’s performance or SEO. This guide will walk you through the key steps to perform a comprehensive HTTPS migration audit.

Pre-Migration Preparation

Start by backing up your website. This includes your database, files, and any custom configurations. Ensure you have access to your hosting control panel and SSL certificate details. Verify that your SSL certificate is valid, correctly installed, and matches your domain name.

Checking for Mixed Content

Mixed content occurs when some resources on your HTTPS page are loaded over HTTP, which can cause security warnings. Use tools like:

  • Browser developer tools
  • Online scanners such as Why No Padlock?
  • Plugins like Really Simple SSL for WordPress

Identify and update all URLs to use HTTPS. This includes images, scripts, stylesheets, and embedded content.

Server Configuration and Redirects

Configure your server to redirect all HTTP traffic to HTTPS. Use 301 redirects for SEO preservation. Check your server configuration files:

  • Apache: Update the .htaccess file
  • Nginx: Modify the server block configuration
  • Ensure redirects are permanent and correctly implemented

SSL Certificate Validation

Verify that your SSL certificate is correctly installed and trusted by browsers. Use tools like SSL Labs’ SSL Server Test to check for vulnerabilities, expiration, and configuration issues.

Testing Website Functionality

Before going live, test your website thoroughly:

  • Ensure all pages load over HTTPS without errors
  • Check forms, login pages, and checkout processes
  • Test on multiple browsers and devices

Monitoring and Post-Migration Checks

After migration, monitor your website’s performance and security. Use Google Search Console to identify crawl errors and HTTPS issues. Keep your SSL certificate renewed and up to date. Regularly review your site for mixed content and security alerts.

Conducting a full HTTPS migration audit ensures a smooth transition, maintaining your site’s security, SEO rankings, and user trust. Proper preparation and testing are key to a successful migration.
