Helium is a 3 year old paid to write website. It is a corporation privately held that is located in Massachusetts, USA. This site is almost similar as the Associated Content.
It pays freelance writers by writing and rating articles. Unlike any other paid to write sites, Helium differs from the way they pay their writers. It is based not only for the page views you can get but mainly being a starred member. A starred member means you gain 1 to 5 stars by writing articles. To obtain a star you need to have at least 75% of writing score. Your articles should top in any competitive titles. You also need to gain 75% rating score to have 1 rating star. That is, every month you are expected to rate at least 10 articles. If you do not maintain rating articles you may lose your star. If that is so, you will not be eligible for payment.
One advantage about Helium is you can join the marketplace where you can get higher earnings from $10 to $100 per article. You can also participate in writing contests. If you want to learn more about writing, you can as well ask for advice from the top and high earning writers. Finally, Helium only pays its writers through paypal service. To earn more, Helium encourages you to invite other writers and get 5% of every article earnings your invited has published.
