There are so many things you can do to get traffic on your blog: blog commenting, article writing and distribution, forum postings, social media optimization, social bookmarking.
Hi I am also a Blog owner and I had tried a tricks which bring quite lots unique visitors to my blog . I had tried to post feeds through feedburner every Thursday between 3PM to 4PM evening . I don't know why there are lots of Listners available and huge amount of readers . You can try this it is a FREE Procedure which can help you. Also saturday now a days I am getting quite lots .
Not quite sure where you get this from - I am using Entrecard and not seen any problems with Adsense. Also not heard of this from anyone else within Entrecard. Entrecard will boost your traffic, but the bounce rate will be high, a small proportion of visitors, however, will actually stick around long enough to read your blog.
I myself would encourage Entrecard. Sure, some of the traffic isn't of any use, but some of it is. And while you are dropping, you will find several blogs with a "u comment, I follow" tag. Leave good, quality comments on their blog posts and most of them will do the same for you. In fact, you should consider adding the tag yourself and then going and commenting on everyone's blog who comments on yours. It's not a bad way to start increasing activity on your blog while building backlinks at the same time.
