SEO is always changing. But the biggest change continues to be the shift toward mobile. Mobile digital media time in the US is now significantly higher (51%) than desktop digital media time (42%), and that number is set to continue to grow. Google recently made mobile page speed a ranking factor. Going forward, if you haven’t already done so, you should look into Accelerated Mobile Pages. It’s becoming more and more paramount to make sure you have no mobile usability issues on your site.
