SSL (Secure Socket Layer) certificates encrypt the communication between your website and visitors, ensuring data security. SSL certificates are vital for protecting sensitive information like login credentials, payment details, and personal data. Google also considers SSL a ranking factor, so having SSL can improve your SEO. To set up an SSL certificate, choose a hosting provider that offers SSL support, either through free services like Let’s Encrypt or paid options. After obtaining the certificate, install it via your hosting control panel or through your provider’s support team. Finally, redirect all HTTP traffic to HTTPS to ensure security across your site.
