An SSL certificate is a digital certificate that encrypts the connection between your website and your visitors’ browsers. When a site has SSL, the URL starts with https:// instead of http://, and visitors see a padlock icon in their browser. It keeps data private and secure in transit.
Why SSL Matters
- Security: encrypts sensitive data like login credentials and payment info
- Trust: visitors trust sites with the padlock; no padlock shows a Not Secure warning
- SEO: Google uses HTTPS as a ranking signal. No SSL means a ranking disadvantage
- Required for payments: you can’t process credit cards without it
Types of SSL Certificates
- Domain Validated (DV): basic encryption, quick to issue, free via Let’s Encrypt
- Organization Validated (OV): verifies the organization, more trust
- Extended Validation (EV): highest trust, shows company name in browser (less common now)
How to Get SSL for WordPress
- Most hosts include a free SSL certificate (via Let’s Encrypt)
- Some premium certificates cost money but offer added warranties and trust levels

SSL is non-negotiable for any website in 2024. The good news: most web hosts give it to you for free.
