Google and Responsive Web Design in 2015
The news is full of articles about Google and responsive web design - and for good reason.
On April 21, 2015 Google has announced they will factor in mobilization as part of their search algorithm. That means your webmaster will need to have designed your site to display optimally on all mobile devices.
Google recommends responsive website design, although it does not favor any particular format as long as the pages are accessible to the Googlebot.
This makes all the sense in the world since all of us are going mobile with our internet searches. Google wants to provide users the best experience possible and if your site is not optimized for mobile it just plain looks bad - let alone is devilishly difficult to read, on a small mobile screen size.
A responsive site uses the same HTML code on the same URLs across all devices. This includes your laptop, iPad, smartphone, etc. This kind of website can display differently based on the screen size. The downside is that a responsive website design usually requires completely rebuilding your website.
But if improving search is important to your business (and whose isn't) it's time to make the investment. Your users will appreciate it and Google will reward it.
