Recently I read a Google article that said Google was now going to favor websites that use Security Certificates. That means your website shows up in the address bar with the letters https://domainname.com rather than http://domainname.com.
Why is this important to Google? First the https encrypts data that your site visitors might send via a web form submission. Second, it ensures that the website is actually the real website your visitor wanted to visit. There are hackers out there that can break into your website and redirect people to a different website. Https ensures this won’t happen because hackers will not pay the money required to make a website secure.
Here is an excerpt from Google Webmasters:
For these reasons, over the past few months we’ve been running tests taking into account whether sites use secure, encrypted connections as a signal in our search ranking algorithms. We’ve seen positive results, so we’re starting to use HTTPS as a ranking signal. For now it’s only a very lightweight signal — affecting fewer than 1% of global queries, and carrying less weight than other signals such as high-quality content — while we give webmasters time to switch to HTTPS. But over time, we may decide to strengthen it, because we’d like to encourage all website owners to switch from HTTP to HTTPS to keep everyone safe on the web.
