More of a minor point on your blog you can also rel=author on your blog to help establish your self as a bit of an authority on your niche (not forgetting the buzz word of rel=canonical too!). This ties in with what Karl said about G= accounts too. Obviously this isn't going to help massively but I'm sure Google trusts this kind of source more.
You can also always take a look at your competitors see why they are ranking better than you and learn a few tips & tricks from them.
Best of luck!
