I have a few websites (accounts) in Google’s Webmaster Tools and have recently received notifications to “fix mobile usability issues”.
How to check if you website is mobile friendly.
Open up your favorite browser, go to your website or the website you need to check, and then reduce the size of the window. Just grab the sides and drag them. If your website is mobile friendly it will re-flow as the window space becomes smaller. If it doesn’t then your website is not mobile friendly.
If your website is responsive then you shouldn’t need a separate mobile version. If you have a WordPress site then installing a plugin such as WPtouch can help.
If you have a website that is not mobile friendly and require assistance to make it friendly, please contact me.
