So maybe you've heard... Google is bringing down the hammer on sites that they don't consider "mobile-friendly".
What does this mean?
In short, you may see a drop in your rankings if your site is not compliant with their Mobile Optimization Guidelines.
How do you determine if your site is compliant, or not?
Well the good news is that Google has created a Mobile-Friendly Testing Tool that makes the compliance evaluation process as easy as cut, paste, click.
