An SSL certificate encrypts data between a visitor’s browser and your website. Modern websites should use HTTPS because it protects information, supports visitor trust, and avoids browser security warnings.
What does SSL protect?
SSL helps protect data such as login details, contact form submissions, and checkout information while it travels between the browser and server. It does not replace strong passwords, updates, backups, or secure website administration.
Free versus paid certificates
Many websites can use a free domain-validated certificate. Paid certificates may include additional validation or support, but the right choice depends on your website and compliance requirements rather than price alone.
SSL setup checklist
- Install a certificate for the correct domain and subdomains.
- Force HTTPS and redirect HTTP pages properly.
- Update WordPress and site URLs to HTTPS.
- Fix mixed-content warnings from images, scripts, or stylesheets.
- Renew certificates automatically where possible.
SSL is only one security layer
Combine HTTPS with updates, strong authentication, limited admin access, malware monitoring, reliable backups, and secure hosting practices.
