All the information you send on the Internet is passed from computer to computer to get to the destination server. Any computer between you and the server can see your credit card numbers, usernames and passwords, and other sensitive information if it is not encrypted with an SSL certificate. With a SSL certificate, the information becomes unreadable to everyone except for the server you are sending the information to. This protects it from hackers and identity thieves.

Phishing email usually includes a link to fake websites or uses a man-in-the-middle attack to use your own domain name. Because it is very difficult for criminals to receive a proper SSL certificate, they won’t be able to perfectly impersonate your site. This means that your users will be far less likely to fall for a phishing attack because they will be looking for the trust indicators in their browser, such as a green address bar, and they won’t see it.

In 2014, Google made changes to its algorithm in order to give the upper hand to HTTPS enabled websites. This has been evident in various studies conducted by SEO experts around the world. So if you want to a better ranking and be on Googles first page or other search engines, you definitely should build your website with SSL.

SSL certificates helps you gaining visitors’ trust. Your website will be displayed with a security padlock in the address bar of the browser. This will indicate that the connection is secure and will show your websites visitors that you take their privacy seriously.
