Since Digicert.com provides free certificates to MVPs, we have added a SSL certificate to our blog and switched to HTTPS on all our traffic. Thank you so much Digicert. This will make sure that all traffic to and from our blog is encrypted.
Google has announced that they will use https as a ranking signal in terms of Google searches. It is therefore considered a best practice to enable SSL on your website. More info about that here: https://webmasters.googleblog.com/2014/08/https-as-ranking-signal.html
WordPress also announced that they will offer free SSL for everyone that is hosted on the WordPress platform (great work WordPress!):
So if you own a blog or a website you should really consider getting a SSL certificate, not only will it make you more secure, but you will also do your webpage a favor when it comes to search ranking.
