Google Adsense and YTD Results

YTD Adsense earnings for Google Adsense:


It's only been half a month (NOTE: the earnings are NOT for this website, it's a different website I run in spanish... so don't feel like you're being robbed, but please, be kind, click the google links on the right)

So far there's a trend that's very apparent... I wish I would get more on impressions and less on just clicks, since my visitors are very inefficient when it comes down to clicking on every single ad they see and they tend to do so at about 1 per every 100 ads

What do you guys do to increase your earnings on your site?
