Google has announced that very soon it will operate two separate search indexes (indices, OK) - one for desktop sites and one for mobile sites. Given that morst searches are these days done by people using mobile devices, it means your site will not show up for anyone searching for your product on a mobile unless you have a mobile compatible site!
In other words, you should have a responsive website. For those that still don't know what this means, a responsive site is coded in such a way that it displays correctly on any device - mobile phone or large Mac desktop computer display. Check out our sites below.
