This criteria can be as simple as inviting women between the age of 18-30 who drink coffee, or a little more specific like; men and women between the age of 18-45, who live in Tennessee and drive their personal car for work 1000 miles or more a month.

These people are then selected to answer a series of questions about a product of business concept, which averages about fifteen to twenty minutes. The average pay for a survey is between $1-$3, but can be more.

If you're looking for something on the Internet for making money, this is about the best you'll find. Unless you're very Internet savvy and can come up with the next hot website, there isn't much else. Finding the legitimate survey websites isn't that easy, though. Like I said earlier, the number of scam sites far outnumbers the legitimate ones.

Using Google or Bing mixes the results with scam and legitimate sites, so one never knows what they're going to get until spend a lot time going through them.

The best way to find real paid survey sites is to use a free survey directory. You should never pay any monthly fees for one of these, some are out there, but you get exactly the same thing with free sites.

If you're signing up with some of the sites listed in the directories and still aren't sure if they're legitimate, look for affiliations with CASRO, the BBB, or TRUSTe.

They ensure that ethical business standards are being followed and maintained. If, in the rare occasion, you have any unresolved and ongoing problems with any of the websites, you can contact the BBB to file a complaint.

Will something happen to the company that runs the website? Maybe, not right away though. But at least if there are enough complaints against them, it will definitely hurt their chances of getting new clients, or losing current ones because of their background.

Keep in mind that any extra dollar you can make doing online surveys is more than what you already had. Plus, you get to make money in the comfort of your own home!
