Started writing a blog to document our startup experiences but no one visits it. Those that visit don't stay. Tried promotion through social media without success. Everyone said it will be easy to interact with those with similar interests. While not the aim to make a profit, currently no chance of making any traction, let alone profit from the blog. http://sparknlaunch.wordpress.com/
It's hard to diagnose, but as other says (and your stats point out), there is something giving a little amateur feel.
From a blog point of view, you should definitely show your authors, to make a genuine, personal impression to readers.
The part of the name of the blog that says 'Biz Startup Tech Blog', it may sound too generic, but also a bit pretentious, and it lacks originality (even if it works from a SEO point of view?). I'll also work on the tagline, to describe better what the blog is about. You could try things like "Personal insights of an entrepreneurial journey", maybe also A/B test it... Tell your visitors you are for real, before they leave.
And last, but not the least, I think the images are not helping. Usually images help make everything a little more attractive, but here, it's not the case. They are giving an amateurish, cheap feel. Try something else on that front. You could avoid the images unless they really illustrate your point with some personal sources: a screenshot from your project, stats, etc.
And please, tell us the results of the experiment!
