This LinkedIn post says it all: “April 21, 2015 – Responsive Reckoning Day with Google . . . It’s official. Non-responsive sites will start ranking lower in Google mobile search.”
So I’ve just spent the past two days pulling my hair out reprogramming this website’s CSS file. The good news is Google’s Mobile Friendly Test says I now pass the grade. To experience the awesomeness for yourself, just grab the right side of your browser window and slowly make it narrower.
Consider this your PSA to get your website affairs in order by April 21! I have visions of Google secret police breaking into houses everywhere, cackling maniacally, as they scream about CSS armageddon. Yeah, it could happen, you know.
