Google recently unleashed an algorithm update that could negatively affect your website. Search engine optimization experts have dubbed it Mobilegeddon, and it’s targeting websites that aren’t compatible with mobile devices.

The update doesn’t affect searches on personal computers, but it does affect searches conducted on tablets and smartphones. Even if you think that doesn’t apply to you, it probably does (unless, of course, you don’t have a website at all). That’s because half of all home shoppers use a mobile device during their searches.

Mobilegeddon takes aim at non-mobile-friendly websites. If you’re not sure whether your site is in good shape, you can use Google’s Mobile-Friendly Test to find out. Unfortunately, sites that don’t pass Google’s test won’t show up in mobile search results (and if you’ve been paying attention to your analytics, you may have noticed a drastic decline in the number of visitors you receive).

If your website isn’t coming up on mobile searches, you’re losing visibility. More than half of your potential clients won’t even see your site when they search – and that can be a disaster, particularly because most home shoppers call only one Realtor®.

Your first move should be to talk to your web developer about making your website compatible with mobile devices. (If you’re still not sure what mobile-friendly means, view the Benchmark Realty website on your smartphone or tablet; you can also change the size of your browser’s window and watch how the website responds.)
