#Mobilegeddon was the rather alarmist name given to Google’s update to their search algorithm which was launched on the 21st April (2015). The scary name was given to it as people were worried about the ramifications of the update.
The update was meant to favour websites which were designed to also function on mobile devices, such as Smart Phones and Tablets. More and more people use these devices, which typically have much smaller screens than desktops and laptops, and sites which are not mobile-friendly can be hard to view; text can appear too small or large, people may have to scroll left and right, and up and down, making navigation difficult. Images can take up too much space, and some technologies (e.g. Flash) are not always supported on mobile devices. These are just a few of the issues.
The update was not only meant to push mobile-friendly sites in search results when people search from mobile devices, but also generally favour mobile-friendly sites when searching from any device. The idea is that all sites should be mobile-friendly, it is 2015 after all.
The fear which many website owners had, is that their websites would disappear from search results. However, the effect has been much more subtle, though some say they have already seen a difference.
If your website isn’t mobile-friendly you should really make it so. As time goes on, if a site isn’t mobile-friendly, it’s safe to assume that it will be penalised more and more.
Making a site mobile ready doesn’t have to be a massive project. In fact it’s possible that your site is already set to go. If you want to check, try Google’s rather useful mobile-friendly testing tool.
What if your site isn’t ready? Your options for doing so are thus; firstly you can create a mobile-ready version of your site which users are redirected to when they visit using a mobile device. The second, and recommended option, is to use a responsive design on your site. Responsive sites automatically resize content and move it around depending on the size of the window the site is being viewed in. Using a responsive design will make things easier for you in the long-run.
