Websites that pay for writing

I have been looking at websites like about.com or inspiredauthor.com or maybe helium which pays writers on a page per view basis. There are other websites who pay writers by sharing Adsense revenue. The concept is to promote the site, promote your page and earn out of the revenue generated from the clicks and impressions or whatsoever was stated in your agreement. Well of course you could earn more because if the site has good content then it will stay on top of the list when someone types a keyword at Google search. But then if it is on a page per view basis or according to your content then it could be the same as creating your own weblog and writing on a niche product. Then as you progress you will learn how to manage your website content and improve your traffic. This way you write on your own site and in the future may be able to improve your page rank through research and blog hopping. What do you think guys? Agree or disagree any choice you make has its own benefits but entrepreneurship is one thing we need to develop if we want to work on our own time.
