An SSL (Secure Sockets Layer) certificate is a digital certificate that authenticates the identity of a website and encrypts information sent to the server using SSL technology. Encryption is the process of scrambling data into an undecipherable format that can only be returned to a readable format with the proper decryption key.
A certificate serves as an electronic “passport” that establishes an online entity’s credentials when doing business on the Web. When an Internet user attempts to send confidential information to a Web server, the user’s browser accesses the server’s digital certificate and establishes a secure connection.
An SSL certificate contains the following information:
- The certificate holder’s name
- The certificate’s serial number and expiration date
- A copy of the certificate holder’s public key
- The digital signature of the certificate-issuing authority
WHY A SECURE WEB SITE
Although only less than 1% of all websites are secure (talk about getting ahead of the competition!), 40% of Google’s page one organic search results feature an HTTPS site. Google has encouraged webmasters to make the migration to a secure site for a while now and has been giving an increasing amount of weight in ranking boosts to websites that are HTTPS. Keep in mind, those sites ranking on page one of Google are also likely following many other best practices in order to gain and retain their valued page one real estate, so it’s not a surprise that of those ranking on page one, more are following Google’s heavy suggestion toward having a secure site!
