The Internet is growing so rapidly and all Web sites need quality and fresh contents. The payment for short articles, usually 500 words or less, is between $15 to $100 and for articles over 1000 words, the payment is as much as $400 or more. And articles can be about anything you want to write about. I was successful with Constant-conten , Helium and Myessays. I still submit my contents on them. All these sites have several options that allow authors to get paid. I also want to add that Myessays has free plagiarism detection scanner and it works perfectly. The only problem with these sites is the popularity. There are many good authors and perfect contents that make the process of selling the articles very slow.
