I attended an Adsense meeting several months ago and there was a big push to get your site mobile-friendly. I do think as more smartphones and tablets are purchased by consumers, this will be an increasingly important issue.
My website developer can get my WordPress site mobile-friendly, but the cost is more than I can afford right now (thanks Panda!).
So are there things you can do to a site to make it more mobile-friendly without a complete redo? Any suggestions would be greatly appreciated.
