I recently created my blog a few months back ,i would really apreciate users to review and tell me where am i missing it , im intended to use it for promotion of clickbank products, online-income-roadmap.blogspot.com
Blogs are very useful to promote goods, web-sites, bands...well, everything. But the question is how good, informative and interesting your blog can be. If you write there new, unique info people will certainly read it. I'm a blogger myself and I you may ask any quesions about promoution through blogs)))
You need to have a decent sized readership before you start trying to make money from it. If you have only a handful of readers, and they find out you only wanna make money off of them, you'll scare most of them away. You need to focus on promoting your blog...the best free methods are social media (facebook, twitter) and seo. Try to build up a large social following and then promote your blog sparingly to them in a helpful way. Then once you have 800 or so daily readers you should start making some decent money. I hope that helps.
