Having an SSL on your website is important.
SSL Certificates are used to establish a secure encrypted connection between a browser, the one on your computer and a server, a website you are visiting.
SSL connection protects sensitive data, such as credit card information or usernames and passwords, exchanged during each visit or session.
If your site has forms that ask for sensitive, personal information you should be using an SSL Certificate. Otherwise, that data is transmitted in clear text and anybody, such as a hacker, could intercept this transmission and collect, store or even sell this information.
Not having SSL on your site could mean that you are missing leads due to visitors not filling out forms on unsecured pages.
