If you type "make money at home" phrase in Google, there is a good chance that you will get at least two or three offers of working by completing paid surveys. Such offers look legitimate, but most of them seem to promise you quite a lot - earning $4000 a month just by completing surveys seem to be a really interesting work at home idea, right?
The point is that you simply can't make more than $100 a month by completing surveys. While such surveys are real and they are really paid (usually from 4 to 20 dollars a survey), it is virtually impossible to receive more than half a dozen of such surveys a month - there are simply too few surveys done to get more. Even those who sign for many such programs at the same time won't get much more - perhaps up to $150 a month maximum. There is simply not enough work for all people willing to take part in the surveys. Paid surveys are a great way to make some extra cash before Christmas, but very lousy full-time job.
To make everything worse, in some situations you have to take into account the possibility that you will not be receiving survey for a few months in a row. It's because most of the time you will fail to qualify for some surveys. If you're young, female, drinking and smoking, your chances grow. If you're old, male and free of bad habits, your chances drop to near zero.
To sum this up: while it is possible to get some money for the surveys, it is a very poor home business idea. With maximum earnings well below $200 a month, trying to rely on surveys alone will make you bankrupt in no time. If you want to work at home full-time, you have to go on looking for some other business idea.
