There's quite a few nice opportunity's to write online and make some decent money. I'll will give you ideas of websites you can join, where you can enjoy writing and earn extra money. Remember, it takes time to start earning a good amount of money. Don't rush, do it because you like writing as well. Slowly start building up a solid rep, and work on one site, then join another.
Write for ehow. Well this is obvious, but this is probably the most enjoyable and great way to make money writing online. It takes time and the key is to write lots of articles, but they got to be well written too. Don't just write junk, otherwise it won't be highly respected and probably won't make you very much. Next three steps I'll tell you how to earn more from ehow with other sites.
Join Xomba. You can write your ehow articles, then post a brief summary of them on Xomba, along with the link to help get more views, WHILE earning money from them as well. You can also use this site to advertise blogs as well, or articles from other sites. You'll need to get a google adsense account, to earn money. It's easy and free, just read their FAQ. Also, to post your ehow articles, blogs, etc, you'll need to post under My Xomblurbs. You can also write articles for them as well.
Join bukisa. Similar to Xomba, you can earn money by writing a short summary of your ehow articles. Also articles from other sites and blogs you can post there as well. Drive more traffic to your sites, while earning from them as well. I'm not yet sold on this site, and haven't really stuck to it much. Not that I think it's bad, I just probably haven't had enough time to really experience much with them.
Join firehow. This is similar to ehow and you can post your ehow articles on here, and make money on this site as well. Just change a few keywords. It's simple and easy. It probably won't generate as much traffic like ehow, but still why not earn more with your articles?
Write for Helium. I've been a member for them for over a month. I have mix feelings about them. My main problem is their rating system is so jacked up. One minute you can be rated number one, then you can be rated rather low. Once you get rated, you can start earning decent money. They pay you multiple of different ways I believe, or so they say. Not a bad site for beginners though. When you join these sites, send links to your other writing sites, along with blogs. It helps.
Write for demand studios. I've not join them, I believe you have to get accepted. I hear they pay quite well though, if accepted. I'm not real familiar with them, but they seem to have a great reputation. Click on the link below if interested.
Join associated content. I joined them about a year ago, but didn't write much. Not because I didn't like them, because I was quite busy and didn't really have time. You can make some good money, if you stick to it. They pay by the view, but I think you can get upfront payments as well. Click on the link below if interested. One million views, means one thousand dollars. They get quite a bit of traffic though.
Join Textbroker. This site does pay, and it pays pretty darn well. I joined and in a day I made 15 dollars pretty easily. You can earn a few dollars just from writing one article. It depends on the demands from the client. I earned 4 dollars for one article. It only took me about 30 minutes. You write on clients request, and some of the articles can be from 100 words, to 400, or more. The more words, the more money. You have to be approved to join, but it's rather easy as long as you can type properly. My only real knock, the writing can get boring pretty fast. You write what a customer wants. They pay you. This is for those who want to earn some money fast. Some of the writing takes some work and a little research though.
Join Suite101.com. Similar to Helium I believe, except I hear they pay much better. I've yet to join, I believe you got to be accepted, which I can't think is too hard. I'll probably join this site eventually. I just can't do 10 different sites at once right now.
Join Bright Hub. They turn me down, but you'll need a writing resume to join. If you get accepted, hey, you can make some nice money through them. They are looking for professional writers, but the pay is rather decent.
Join constant content. I've not fooled around too much, but this is similar to Textbroker, accept the pay seems a lot better. You can sell articles you've written on their site, set your own price on them. You can also write for requests and earn some nice money. Join them, read their FAQ. Click on the link blew if you want to join. I'm definitely going to get more active with them, once I get more time on my hands.
Send your articles to search engines on submit express to get more views.
Join vinefire. Okay, I am very skeptical about this site. Here's the run down on them. When you click on links from this site, you earn money. You also can send your own links to their site, and earn four cents anytime someone clicks on them. You can earn up to 100 dollars a day doing this. There's a limit though, if you don't pay their 5 dollar fee. If you decide not to pay it, you only can earn up to 10 dollars a day. Although their rates do change, I can't promise it stays the same. I haven't yet paid it, because I don't trust them. They claim once someone buys their site, they'll start paying. That's the catch, you can't cash out with them yet. They expect at the latest to sell by January 2010. I honestly don't ever expect to be paid, and I really don't care. The thing I am interested in is whether I can drive TONS of traffic to my site through them. So far I'll admit my views have gone up. If you have a blog, or articles from here, you might want to send them to this site. Blogs and articles that are about making money are extremely useful. People will click on them and your views should increase. I'm experimenting with them and I might write a article about them.
