For $1.89 a minute a rate she set the 39-year-old from Marianna, Fla., dispenses advice to clients around the globe. She spends about four hours a day online, often at night, when her daug

5、hter has gone to bed. “It was the economy,” she says of her move to take her skills online. “Live Person is more profitable than my private practice.” Ms. Estes had charged her private clients up to $75 an hour. As the recession deepens, a small but growing number of people are taking their skills o

6、nline, offering expertise or performing specified tasks for a fee. Labor-at-the-keyboard sites are gaining popularity as people increasingly turn to the Web in search of work. Internet job-search sites saw a 51% rise in traffic from January 2008 to January 2009, according to comScore Media Metrix, t

7、o 26.7 million unique visitors. 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, inclu

8、ding mental health, financial services, shopping and fashion, as well as psychics and spiritual advisers. Mechanical Turk, a Web service run by A Inc., pays workers to perform tasks, such as cataloging products online. Associated Content pays contributors to write articles on a wide range of subject

9、s, 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 Chi

10、ef 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. S

11、ome 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 a

12、nd 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 sit

13、e 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

14、 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 speci

15、fic profession, such as law or real estate, helps raise a persons 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 As

16、sociated 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

17、 and often looks for newsy ideas that will attract readers. Mechanical Turk, by contrast, is based on “crowd sourcing”, or breaking a task into lots of tiny pieces and giving it to a big group of people to complete quickly. Most of these jobs which the site calls HITs, for human intelligence tasks p

18、ay just a few cents. Efficient MTurkers, as they call themselves, can make more than $100 a week doing things such as finding someones email address or labeling images of a particular animal in a photograph. Amazon says that MTurk now has 200,000 workers from 100 different countries, but it doesnt k

19、eep track of past figures. The site named for an 18th-century stunt involving a turbaned chess-playing “machine” with an actual chess master hidden within began as a way to help Amazon manage its product database, says Sharon Chiarella, vice president of Amazon Mechanical Turk. Amazon uses the site

20、to help sort images and content, paying people a few cents a task. Mechanical Turk also serves a variety of companies who need Web tasks performed, especially those that require a human element. Test-prep startup Knewton Inc., for example, uses it extensively for focus-group-type tasks, as well as e

21、nlisting people to take its practice tests. Keri Knutson, a mother of five from Independence, La., discovered Mechanical Turk when her eldest son was headed for college. Ms. Knutson, now 45, needed money for his tuition and fees. She took on all kinds of low-paying but easy tasks at the beginning, f

22、rom finding a place to purchase a specific item to identifying the name of a street in a photograph. People looking to make money online as fee-for-service experts should read the fine print. Live Person has one of the more formal payment systems, requiring users to sign up for an account before tal

23、king with an expert. Some sites, including Associated Content and Mechanical Turk, reserve the right to refuse payment if a task is not completed satisfactorily. Most sites have a robust community of workers who regularly offer one another tips on which tasks pay the best. Mechanical Turk users have

24、 an independent site called Turker Nation (), which reviews the companies that solicit (索求) and pay for tasks so that workers can check a companys record before taking on a task. Consumers who use these sites also need to exercise caution. Relying on legal or medical advice from an unknown online so

25、urce has obvious drawbacks, and the Web sites acknowledge that some users have registered complaints about the advice offered on the sites. LivePerson warns consumers to offer their financial and personal details with care. For the workers on these sites, even incremental sources of income are helpf

26、ul these days. Ms. Knutson now spends the majority of her time transcribing Web audio and video for clients, earning about $250 a week for 30 hours of work. She says she has seen more competition lately but is determined to keep up her weekly pace. “If I didnt have this money,” she says, “wed be str
