Choosing the right SSL Certificate. You will start considering purchase of SSL Certificate for your website once you start collecting user’s sensitive data. It doesn’t have to be specifically credit card information but any information that your visitors consider private, like home address or phone number. You will need a separate dedicated IP address to setup your SSL certificate, so if you are using shared hosting, make sure that your service provider will be able to provide you one. There can be additional charges associated with setting up a dedicated IP for you. So make sure that you’ve taken all the costs into account.
