Launching late last year, PayU2Blog is another new entry in the growing realm of sites and programs that offer chances for bloggers to add sponsored posts to their blog for a decent payment. While it was not the first or necessarily the best of any of these type of sites, it has become a very popular option because it is simple, doesn’t impose a wide array of different restrictions on its bloggers.

Signing up for PayU2Blog is fairly simple. Upon visiting the site at PayU2Blog.com, you’ll find a few options. The website features a FAQ for those new to writing blog posts for money as well as a company blog, testimonials and all the usual website features such as contact links, about us pages, and a forum to discuss the site with other bloggers. Basically, PayU2Blog wants to make sure you always have all of the information you need to know that they are legitimate. It is a good step above the features offered by many sites that have popped up in recent months.

After signing up and having your blog approved (it takes between 2 and 5 days to get approval, depending on the back log of sites), you will gain access to the members area of the site. In this section, you are immediately shown your assignments, a list of keywords and URLs that you must integrate into a blog post of at least 100 words, a very easy task most of the time. Depending on the page rank and quality of your blog, you will be given a variable amount of assignments each week, usually between 1 and 5 per blog you add to your account.

The set up is simple, payment is done every two weeks through paypal, and the keywords can be integrated into posts in whatever manner you want (occasionally there are rules attached to a project, but very rarely). Payment is $5 per post and with an average of 3 per week or more, that’s a quick and easy $60 a month you can make for writing about 1200 words on your blog - something you’ll aready do. You don’t have to mark your blog as being sponsored and you do not have to write about a specific topic - just integrate the keyword and link.

Among the bevy of services like PayU2Blog, this one is a good choice. It doesn’t offer the highest pay or the most options in your account, but it is solid and consistent and a good way to supplement income over time.

Among the first websites to offer the “micro-pay format” Helium.com has been one of the more interesting to watch as it has developed. I originally signed up for Helium.com about a year ago when I was researching and testing the various sites on the Internet which claimed to offer pay for writing. Unlike Associated Content, the concept behind Helium was originally based on the forum style writing that so many Internet users were used to.

Upon entering the website, Helium introduces its visitors to a variety of channels and front page content. The articles are listed by a specific title and topic within which multiple actual articles might appear. Writers can choose a topic which already has articles written and write their own “take” on that topic. Other writers and visitors then vote on which of the multiple articles might best represent the article title. Helium is unique in this regard as no other website allows members to compare and vote on paid articles in the same manner.

The money comes in when writers create articles that generate large sums of traffic. Helium places ads throughout their website and on each page. When a visitor clicks on an ad, you get a small percentage of that advertising money. The money adds up depending on the amount of traffic your content generates and how much content you are able to generate. Obviously front page content gets more traffic and occasionally, if you have written a particularly high ranked article, it can hit the front page.

Unfortunately, the main problem with Helium is that the site pays very little for page views. It’s not because they are keeping money for themselves as much as the multiple articles located under the same title do not all show up at once. To really make money on Helium, writers need to consistently rank in the top one or two spaces and hit the front page repeatedly.

Because of an ample advertising campaign, the site has grown to exorbitantly large proportions in recent months and reaching the top can be harder than it once was. To make solid money on Helium, it can take a lot of time and investment.

Of course, the point is not necessarily to make money with these articles. Instead, Helium has now integrated a marketplace that allows writers to make real money. Through the marketplace, companies and magazines will post article requests for writers to fill. Additionally, there are plenty of contests for writers that allow top notch Helium members to make a few extra dollars for their posts.

Ultimately, Helium is a great place to start for anyone wanting to get in contact with writers and practice their craft for a few extra cents every couple days. But, for a freelance writer hoping to make a few extra dollars for their articles, it is definitely not the most viable option. Even sites like Xomba pay a little better as they reimburse writers with all of the adsense payments. However, for a full feature set and a marketplace option. Helium has a slight edge.

The final verdict: when first starting out, check out Helium and write a few articles. When trying to actually make a few extra dollars, start with Associated Content and work your way up.

Despite its simple nature and essentially non-existent growth in the past decade, About.com has become a very popular source of common knowledge and how-to articles on thousands of topics. With a high page rank and a few dozen quasi-experts in their fields, they consistently show up on the top of search rankings for any number of topics.

With the money About.com makes from those search rankings and the amount of traffic that tends to pour in from Google and the like, they have a bit of capital with which to ensure they hire quality writers to keep up their columns.

Basically, it’s a living, constantly adapting news encyclopedia with real freelance writers operating the switch boards for the topics that you can so easily find at random. Each article has a real name and picture attached to it, unlike so many other amalgamated news sites and for that reason, there needs to be several hundreds writers on staff at any given time.

Because About.com has built up such a steady, repetitive traffic source, it can afford to pay decent dollar to its writers on a regular basis. It doesn’t hurt that the New York Times owns the site now and tries its best to keep the quality of writing as high as possible.

Anyways, the point of all this is that About.com allows freelance writers (or just plain unemployed writers) apply to be guides on their site. In the lower right corner of any About.com page is a link “Be a Guide”. This takes you to a section that lists the available guide positions and the compensation, hiring process, and a few other choice details.

Basically, About.com pays you on a sliding scale for the traffic you generate as a guide. You write a few articles every month, upload links and track changes in a given field and About.com pays you a minimum of $700 a month. The contracts usually span a year at a time and if your page views explode enough you can make much more money eventually – About.com claims some of their guides make as much as $100,000 a year.

As a freelance opportunity, About.com borders on being a part time job more than anything. You must apply to work with them, complete a 2 week prep course and write sample materials. However, if you get chosen (they usually have around 30-50 open topics at any given time) you can essentially cover half of your monthly workload with a single job – a nice touch of security in the frantic life of a freelance writer.
