I just made my first AdSense site today, and I would like tips to improve it for more income like where to place adds, what to add to the site, I read the Rich Jerks guide to getting rich or whatever it's called, and so I decided to make a college site, since it had high payments. Any tips at all for improving my site or even for making a completely new AdSense site(if mine's that bad) would be appreciated. My site is www.collegecrazy.tk
First off, don't design a site JUST for adsense, that will never generate you significant income. Build a site, a strong site, then implement adsense and you will be much more successful.
Your page is not going to rank well. Looking briefly at your content I note that it seems a little to dense with keywords where you have writtten sentences yourself. Compare the density to the standard for high ranking pages for those keywords and aim for that. The duplicate content you got from free articles is unlikely to tickle the search engines fancy (and you have not given credit to the author as per the terms of the article use agreements so if it ever does serp well the original author is likely to get you banned from the search engines)
Thanks, and I'll make sure to add the author, I didn't know I needed to credit them since they were free.
