Business or personal website Unless you sell things on your personal website, a Standard SSL (DV) is fine. This is also true for informational business sites. eCommerce websites should use a single-domain Standard SSL (DV) or Premium SSL (EV). If you need to protect different domains Wildcard SSLs cover multiple subdomains. For example, use a Wildcard to protect *.myexampledomain.com, which would cover store.myexampledomain.com, www.myexampledomain.com and any other subdomains. UCC SSLs will cover multiple domains, subdomains and websites. For example, you can secure www.myexampledomain.com, mail.myexampledomain.com, and www.myexampledomain1.com
