The best way to receive surveys is to sign up with as many survey companies as possible. Some people report taking surveys right away - anywhere from a few hours to a few days after they start registering. But many companies only send out a few surveys per month, so it will usually be a few weeks before you start getting a lot of surveys. Again, this depends on how many companies you register with and your personal "profile." Everyone's experience is a little different.
However, you MUST register with the companies in order to receive surveys. You can locate the database in the members area under the tab "market research companies." You must be logged in to access it. Please register with the companies listed in your country as well as those listed as WORLDWIDE.
