Without a valid SSL certificate, browsers show visitors a “Not Secure” warning before they read a word of your site. Google has treated HTTPS as a ranking signal since 2014, so an expired or missing certificate costs you both trust and visibility.
A standard domain-validated certificate covers most business sites and issues within minutes. If you take payments directly, an organisation-validated certificate adds verified business identity. Running several subdomains makes a wildcard certificate cheaper than buying each separately. See also website security and firewall.
If you would rather not track expiry dates, validation emails and reinstallation yourself, the managed service handles issuing, installing and renewing the certificate for you. It suits businesses running several sites, or anyone caught out by a certificate lapsing over a weekend.
Yes. The browser warning appears on every site without it, and visitors leave rather than click through a security warning.
Browsers block the site with a full-page warning. Auto-renewal prevents that, and we monitor expiry dates for sites we manage.
