Secure Sockets Layer. Just in case you were wondering what that acronym in the title meant. This essentially is a technology that secures the connection between your browser and the website that you’re visiting. i.e. when you see https: instead of just simply http: then you can be assured that there's an SSL setup and that the connection is more secure.
What does that really mean?
- More Privacy. So, when you're logging into a website, such as your bank, this setup goes the extra step and encrypts that information so that it is transmitted securely.
- Stops Unauthorized Changes. Basically, no one can change the information during transmission.
- Authenticity. This setup also requires the web server to essentially prove that it is who it says it is.
Also, a plus to having the SSL setup is that it can actually improve your rankings in the search engine. I wouldn't get the SSL setup for this reason, but it can't hurt.
What to Remember: you want every site to have an SSL setup, but don't even consider entering sensitive information into a site if you don't see https:.
