　　Among the many fee-for-service Web sites out there, at least three are attracting a significant number of users — though consumers should exercise a healthy degree of skepticism when consulting any of these sites. Live Person seeks out experts on a slew of topics, including mental health, financial services, shopping and fashion, as well as psychics and spiritual advisers. Mechanical Turk, a Web service run by Amazon.com Inc., pays workers to perform tasks, such as cataloging products online. Associated Content pays contributors to write articles on a wide range of subjects, from organic flower gardening to how to apply for financial aid.

　　Live Person went public in 2001, and the current version of the site was launched in late 2007. Today, the site has 30,000 registered experts, attracting an average of 100,000 people a year who pay for the offered services, says Chief Executive Officer Robert LoCascio. Roughly 3,500 people have made contributing to the site their full-time job, he says.

　　Live Person says it vets contributors’ qualifications, such as medical licenses or financial certification, through a third party, and relies heavily on its community reviews. Some 200 people a day apply to be Live Person experts, up from 120 a year ago, says Mr. LoCascio. Once cleared, advisers work with clients on a cost-per-minute basis set by the adviser. The site takes a commission of between 30% and 35%.

　　Associated Content, by contrast, reviews submissions in house and then decides how much to pay for them. The site, which specializes in how-to pieces and feature stories on news topics, had 237,000 registered contributors and more than one million content pieces as of February, both about double from the same month a year ago.

　　After posting the content, the site sells advertisements against it and distributes it to other companies, such as online shoe retailer Zappos, which use the content on their own Web sites. If Associated Content accepts a submission (it says it rejects about 25% of them), the author gets between $5 and $30, plus $1.50 for each 1,000 page views. An ability to write “search-engine-optimized” content, an industry term for generating good Google results, helps, says site founder Luke Beatty.

　　People are not only looking for payment but also establishing their credentials “as somebody with experience”, he says. Writing about a specific profession, such as law or real estate, helps raise a person’s profile online, enhancing his job searches, says Mr. Beatty.

　　Sabah Karimi, a 26-year-old from Orlando, Fla., left a career in marketing to become a full-time freelance writer and now spends between 8 and 10 hours a week writing for Associated Content. She has been at it for about three years and says she earns roughly $1,000 a month from her past and current submissions.

　　Ms. Karimi cautions newcomers to Associated Content that it takes time to build up earnings. She says she learned how to write articles that would bring traffic and often looks for newsy ideas that will attract readers.
