Do you know why some website addresses begin with "http" while others start with "https"? That "s" stands for secure, and it means the site you’re visiting is using a protected, encrypted connection. That security is provided by a Secure Socket Layer (SSL) certificate. Websites that accept credit card payments and other secure information have been required to have SSLs for a long time, and recently there has been a push to make the entire World Wide Web adopt this level of security.
I don't accept credit cards online. Why do I need SSL?If your website does not have an SSL certificate, and it contains any kind of text input, even a basic contact form or newsletter sign-up script, Google Chrome now warns visitors with a notice that reads:
Your connection to this site is not secure. You should not enter any sensitive information on this site (for example, passwords or credit cards), because it could be stolen by attackers.You may not be collecting passwords or credit card information, but that notice will be enough to scare away a sizable chunk of your site's visitors. Also, Google ranks sites with SSL higher than those those without it.
