Why SSL is so important for your sites, and your business

When your site has an SSL certificate, the connection between site visitors and the site is secure. This means:

Data transferred between the site and its visitors is encrypted, so no one can intercept it.
Content on the site can’t be changed by anyone other than the site owner.
Site visitors see a lock icon in the address bar, boosting the site’s brand reputation and increasing visitors’ confidence and trust.
When there’s no SSL certificate, browsers indicate that the site is “Not secure”; this discourages visitors from browsing.
The site gets a SEO boost for having HTTPS enabled on it.
