RSS stands for “really simple syndication,” or, depending on who you ask, “rich site summary.” At their heart they are just simple text files with basic updated information — news pieces, articles, that sort of thing. That stripped-down content is usually plugged into what is called a “feed reader” or an interface that quickly converts the RSS text files into a stream of the latest updates from around the web.
As internet content became more complex, so did RSS files, which quickly adopted images, video, and more, but still in a stripped down format for easier loading and compatibility across all feed readers. Readers usually automatically update, so that they delivers the newest content right to your device. Basically, this approach allows internet users to create their own online feed filled with custom updates from the sites that they like to visit regularly.

An SSL Certificate (Secure Sockets Layer), also called a Digital Certificate, creates a secure link between a website and a visitor's browser. By ensuring that all data passed between the two remains private and secure, SSL encryption prevents hackers from stealing private information such as credit card numbers, names and addresses.
If you sell products or services on your website and accept credit cards online, you need an SSL Certificate for website security. If you don't sell online but want to add credibility to your website, a Site Confirm Seal may be sufficient.
