According to Google:
“Starting April 21, we will be expanding our use of mobile-friendliness as a ranking signal. This change will affect mobile searches in all languages worldwide and will have a significant impact in our search results. Consequently, users will find it easier to get relevant, high quality search results that are optimized for their devices.”
Yes. Starting April 21, 2015, if your website isn’t “responsive” or mobile friendly, your competitors will be outranking you in the search results.
As of April 21st, Google will not only label your website “mobile-friendly”, they will also use that label to determine where to place your website in the search results.
Of course, having a mobile friendly site has been used in Google’s algorithms for a long time now. However, this new update as of April 21, 2015 will have an even larger impact on websites. It will reward sites with mobile friendly pages, leaving non-responsive sites in the dust!
Bottom line: If your website was built without the ability to adjust to various size devices and your competitor’s website has this functionality, they will appear higher in the search engines than your website. Thus, your competitors will get a larger share of website traffic.
