It authenticates your website’s identity, providing trust and security for users. An SSL certificate is crucial for any website that handles personal data, processes payments, or requires user logins. Additionally, search engines like Google favor websites with SSL certificates, boosting your site's search rankings. You can identify a site with SSL by the padlock icon and "https" in the URL.
