“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.”
This update will impact only mobile searchers and it will give a ranking boost to mobile-friendly pages in Google’s mobile search results only. It will only impact mobile searchers and will have no impact on your desktop rankings.
One of the best ways to to test if Google considers your web pages to be mobile-friendly is using its own Mobile-Friendly Test tool.
If your website “fails” this test, it’s time to rethink your presence on the web and make your website responsive or provide it with a mobile version. And this is where we come in.
