How to convert your WordPress site from http to https for SSL Certificates

How to Secure Your WordPress Site with HTTPS in 2025 (Australia Guide)

In 2025, having a secure website is no longer optional—it’s essential. Google continues to prioritise secure websites in its search rankings, and the Chrome browser flags all non-HTTPS (HTTP) sites as “Not Secure”, which can hurt user trust and SEO.

If you’re running a WordPress website, converting your site from HTTP to HTTPS using an SSL certificate is one of the fastest ways to improve your security, credibility, and visibility online.

Why You Need to Install an SSL Certificate in 2025

Google’s ongoing push for secure websites means that SSL (Secure Sockets Layer) is now a ranking factor in Australia and worldwide. Without HTTPS, your website may:

  • Display a “Not Secure” warning in browsers
  • Lose visitors due to trust concerns
  • Rank lower in Google search results

Common Issues After Installing SSL on WordPress

After installing your SSL certificate, your site might still load some mixed content (images, CSS, or scripts using HTTP). This can cause your padlock icon to be missing or for your website to still appear as not fully secure.

Best WordPress Plugin for SSL: Really Simple SSL

One of the easiest ways to ensure full HTTPS compliance is by using the Really Simple SSL plugin. This tool:

  • Automatically detects your SSL certificate
  • Redirects all traffic from HTTP to HTTPS
  • Updates internal links and dynamic content
  • Fixes mixed content issues without manual coding

 Important: Before activating the plugin, always create a full backup of your WordPress site, as it modifies database entries and configuration settings.

Step-by-Step: How to Convert WordPress from HTTP to HTTPS

  1. Purchase and install your SSL certificate through your hosting provider or a third-party vendor.
  2. Install the Really Simple SSL plugin from your WordPress dashboard.
  3. Activate the plugin and follow the on-screen prompts.
  4. Verify your site now displays the secure padlock and all content loads over HTTPS.
