If you have been following this blog, you may have noticed that the design has changed last week. The blog is now responsive and supports rendering to a mobile browser.
One of the reasons this important is that Google is updating their page ranking algorithms. This is something that happens often where minor changes are made. There are also times when a major change happens that has a major impact on the ranking of your site. Except for SEOs most people do not follow this closely.
The difference this time is that Google also change has a major support for mobility. So if your page does not support rendering in mobile browser, then it will get a lower score as per the new algorithm when the search is from a mobile device. So it is important that you make sure that your pages are optimized for mobile.
As per this post
