I've got a Fry's electronics banner, an ad for blogspot, and an ad for creating apps. I can see why your readers aren't clicking. I think Adsense is totally wrong for this kind of blog.

While you have a lot of content I will be honest that it doesn't provide a lot of value. Anyone who is more than an extreme beginner level will not find much use for your blog. It honestly sounds like you're new to SEO and you're barely learning. It looks like you're giving it an honest attempt, but I'd suggest focus your efforts elsewhere.

It is obvious in your writing style that English isn't your first language. Grammatical errors can hurt your credibility with readers. You should think about hiring an English speaker to proof your articles.

I would never put Adsense on a site like this. So many posts "High PR comments list" etc... Essentially what you're saying is "Hey Google I'm showing people where they can go to manipulate your search results" and at the same time you are placing their advertising code on your blog.

Personally I feel like this is asking for trouble.

Thanks for good advice. Definitely i will follow all the steps.
