For all you jQuery fans, sorry! We’re not discussing the practice of moving through the Document Object Model. Instead, I’d like to refer back to the series of articles recently published about the is responsive.

Given that the last few years have been “The Year of Mobile,” I’m proposing we re-purpose the phrase to, “The Decade of Mobile.” And this is where we must understand how to traverse the DoM.

You might recall that in November of 2014, Google introduced the “mobile-friendly” label to the search engine results on mobile devices. And now, as of April 21, 2015, Google is making the “Year of Mobile” official with their upcoming changes to the search algorithm.

When it comes to search on mobile devices, users should get the most relevant and timely results, no matter if the information lives on mobile-friendly web pages or apps. As more people use mobile devices to access the internet, our algorithms have to adapt to these usage patterns. In the past, we’ve made updates to ensure a site is configured properly and viewable on modern devices. We’ve made it easier for users to find mobile-friendly web pages and we’ve introduced App Indexing to surface useful content from apps.

So what does this mean for your business? If you don’t have a mobile-friendly site, you will be impacted by the way your content is listed for mobile users. A good practice to start now is reviewing your mobile traffic in your analytics platforms. Something you can do today is using the Google Mobile-Friendly Test. This test will ensure your website meets Google expectations for a mobile-friendly site.
