How to Set Up SSL on Your WordPress Site for Free
SSL protects the connection between a visitor’s browser and your WordPress website. Once it is active, your address begins with https:// and browsers display a padlock or security indicator. SSL is commonly delivered through a TLS certificate, so you may see both terms used by your hosting provider.
For bloggers, small businesses and online shops in Australia, HTTPS is a basic requirement rather than an optional extra. It helps protect login details, contact forms and checkout information while giving visitors in Sydney, Melbourne, Brisbane and regional areas more confidence when browsing your site. You can usually install a free certificate through your web host without buying a premium security package.
Why HTTPS Matters For WordPress
An SSL certificate encrypts data sent between a website and its visitors. This reduces the risk of passwords, form submissions and payment-related information being intercepted on public Wi-Fi, home networks or shared connections. It is especially important if your WordPress site includes user accounts, newsletter forms, bookings or WooCommerce.
Search engines also use HTTPS as a ranking signal, although it will not automatically move a site to the first page of Google Australia. A secure address can improve trust and reduce warnings that cause visitors to leave. Australian customers often look for a padlock before entering details, particularly when buying from a smaller local business or a new .com.au website.
Check Your Hosting And Domain Setup
Before installing SSL, confirm that your domain points to the correct hosting account. Log in to your registrar and review the DNS records. An A record usually points the domain to your hosting server, while a CNAME record may be used for www. If you recently moved from a host in Melbourne to a server in Sydney, DNS changes may still be spreading.
Check whether your hosting dashboard includes free Let’s Encrypt SSL certificates. Many Australian and international hosts provide an SSL, Security or Let’s Encrypt option inside cPanel or a custom control panel. Make sure the certificate covers every version of your domain that visitors may use, including:
example.comwww.example.comexample.com.au, if applicable
If your DNS is managed through Cloudflare, confirm whether the encryption mode matches the certificate installed on your server. The “Flexible” setting can create redirect loops because Cloudflare connects to the server using HTTP. “Full” or “Full (strict)” is generally safer when your origin server has a valid certificate.
Create A Backup Before Changing URLs
Changing WordPress from HTTP to HTTPS affects the site URL, internal links, media files and sometimes database entries. Create a complete backup before making changes. Save both the database and website files, and check that the backup can be restored through your host’s system.
You can use your host’s backup tool or a trusted WordPress backup plugin. If your site generates regular sales from customers across Australia, schedule the change during a quiet period rather than just before a promotional campaign or a busy weekend. Keep your hosting support details available in case the site shows a redirect error.
Install The Free SSL Certificate
Open your hosting control panel and look for labels such as SSL/TLS, Let’s Encrypt, AutoSSL or Security. Select your domain and enable the free certificate. Some hosts issue it immediately; others may take several minutes while the certificate authority verifies your DNS records.
The options vary between providers, so use this guide as a general path:
| Hosting setup | Usual SSL method | What to check |
|---|---|---|
| cPanel hosting | SSL/TLS Status or AutoSSL | Include the root and www domain |
| Managed WordPress hosting | Security or Domains screen | Confirm HTTPS is enabled automatically |
| Cloud hosting | Server panel or command line | Verify DNS and web-server configuration |
| Cloudflare in front of hosting | Cloudflare SSL/TLS settings | Avoid Flexible mode with a server certificate |
| VPS hosting | Certbot with Let’s Encrypt | Configure automatic renewal |
After activation, test https://yourdomain.com in a private browser window. If the certificate is active, the browser should show a secure connection without a certificate warning. Repeat the test with the www version if you use it.
Update WordPress To Use HTTPS
In the WordPress dashboard, go to Settings and then General. Change both “WordPress Address (URL)” and “Site Address (URL)” from http:// to https://. Save the changes, then sign in again if WordPress logs you out.
If you cannot access the dashboard after changing the URLs, update the values through your hosting file manager or database tools. In wp-config.php, temporary constants can force HTTPS:
define('WP_HOME', 'https://example.com');
define('WP_SITEURL', 'https://example.com');
Replace the domain with your own address and avoid adding these lines if the values already exist. Another option is to update the home and siteurl rows in the WordPress database, but make a backup first because an incorrect database edit can take the site offline.
Redirect HTTP Visitors And Fix Mixed Content
A certificate does not automatically redirect old HTTP links. You need a permanent 301 redirect so visitors and search engines are sent to the secure version. Many hosts provide a “Force HTTPS” switch. If yours does not, a security plugin such as Really Simple Security can help detect the certificate and apply the required settings.
You can also configure a redirect in .htaccess on Apache hosting, but do not add rules blindly if your host already manages redirects. A typical rule is:
RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
Mixed content occurs when the main page loads over HTTPS but images, scripts, stylesheets or fonts still use HTTP. Use a site-crawling tool or browser developer tools to locate those resources. Update hard-coded links, replace old image URLs in the WordPress database with care, and check page-builder settings. Do not simply ignore mixed-content warnings because blocked scripts can break menus, forms or WooCommerce features.
Verify The Whole Website
Test the homepage, contact form, navigation, images, comments, login screen and checkout if your site sells products. Open the pages on a phone using mobile data as well as Wi-Fi. This is useful for Australian visitors in areas where connection quality varies, including regional Queensland, Western Australia and outer suburban areas.
Check that HTTP versions redirect once to the preferred HTTPS address. A chain such as HTTP to www to HTTPS can slow loading and create configuration problems. Run the site through an SSL checker and review the certificate name, expiry date, supported protocols and intermediate certificates.
Update Google Search Console with the HTTPS property and submit the secure sitemap. Review Google Analytics or another analytics platform to confirm that visits and referral data continue to record correctly. If you use social media profiles, email campaigns or business listings, update important links to the secure URL, including profiles aimed at customers in Australia.
Keep The Certificate Renewing
Free Let’s Encrypt certificates commonly last for 90 days, but reliable hosting platforms renew them automatically. Visit the hosting dashboard after installation and look for a renewal status or expiry date. Set a calendar reminder or monitoring alert so an expired certificate does not suddenly display a security warning.
Keep WordPress, themes and plugins updated, particularly security and caching tools. Clear your site cache after forcing HTTPS, then purge any CDN cache so visitors receive the latest redirects and stylesheets. Review the site after major hosting, DNS or Cloudflare changes because a server migration can remove certificate settings.
Once HTTPS works correctly, remove unnecessary SSL plugins and duplicate redirect rules. A simple configuration is easier to maintain and less likely to create loops. Continue checking the site after updates so your WordPress installation remains secure for visitors using desktop and mobile networks across Australia.
Apply these steps to move your WordPress site to HTTPS without paying for a certificate. Back up first, activate Let’s Encrypt through your host, force secure URLs, repair mixed content and verify every important page. A working SSL setup improves visitor trust, supports safer online transactions and gives your .com.au website a stronger technical foundation.
