In my swedish blog, I blog about 5 times/day since I'm quite famous. On my English blogs it's about 1 post if I'm lucky.
If you post 10-20 times a day, then you're not posting much quality content... try posting three times a day, with really long posts instead.
I've been posting every day too but have had no comments...and I don't think I've had any visitors either.
First install google analytics to keep track of visitors. Next do some promotion for your blog. commenting on other blogs (dont spam), social media marketing (twitter, facebook, youtube, etc.), and last do some link building with author text to rank for your given keywords. (that is if you did your keyword research)
I post about four or five posts each month. I do diligent keyword research in front to ensure that I maximize the traffic from search engines and use SEO plugins and put a great deal of time and resources into this. I recommend putting some extra time into the keyword research since this in combination with SEO gives better and more relevant ads (more clicks) and a better earn-out on your page if using Google Adsense!
