Starting April 21, Google will be expanding their 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 their search results. Consequently, users will find it easier to get relevant, high quality search results that are optimized for their devices.
This means that if your site is not mobile-friendly, your site will not be as relevant in the search results.
If you are a THUD Client, and your site has not been redesigned in the past 12-months, this directly affects you and your business. Call us today so we can coordinate a plan of action to keep your site indexing properly.
You can see Google's Blog post on this change here, which was posted February 26, 2015.
