Just noticed a new tab in Webmaster Tools while doing some checking, looks like it's actually been there since mid October.
Google will now give you specific information on mobile friendly issues of your website, telling which pages have problems, what they are and tools to rectify them.
If you select the Search Traffic tab, you will see a new Mobile Usability Option.
If you then select any error that is being displayed, a new window will open up and give you more information as well as some help and tools to resolve them, including the very impressive (and in my mind essential) PageSpeed Insights.
All good stuff. Looks like I've got a few things to look at, but remember this is things Google thinks are wrong based on automated assessments, so don't take it as gospel. Investigate, examine the issues and decide if they are an actual issue based on your own data and experience.
Any questions or anyone wants a second opinion, just shout.
If you aren't familiar with Webmaster Tools, then you can learn about it here:
