You didn't tell about the niche of your site. It's good if you tell your website URL so we can visit your site to give you valuable suggestions.
So, something wrong! what kind of site do you run? What do you mean saying unique content? Is it text or pics? Where do you get traffic? There a lot of questions. need more info
Without even seeing your site, I can probably surmise that if your click through rate is not at least 1-2%, your ad placement is wrong. If you are getting 1000 visits per day, you should be seeing 10-20 clicks. If that is what you are seeing click wise, it can only mean the value of your click is very low, maybe it is not a good niche for adsense. Hard to say without knowing more about your website.
You should have your Ad's above the fold. You can see this article on where to place your Ad's http://www.bloghunk.com/where-to-place-google-adsense-ads-for-maximizing-high-earnings.html
