As of the 21st April 2015, Google will be handsomely rewarding sites that are optimised for mobile. With the constant rise in popularity of mobile search, as well as mobile commerce, Google wants to ensure that they are directing their users to sites that will work well on their devices. Remember that ultimately Google wants to provide the best user experience for their searchers, as that's how they stay as the world's top search engine. These changes will affect every country currently using Google, and will apply to results in all languages. If your site is not mobile-ready, you will be penalised. Don't worry though, we've made it easy by constructing a guide of how you can respond to these changes before D-day!
