The number of surveys you get depends on your profile and how many research companies you are a member of. You increase your chances of qualifying by filling out as much details about yourself in your profile as possible. You can get started by just filling out the basic information but filling in detailed information means that you can be targeted much more specifically by businesses who are looking for consumers who match your description.
There is no reason to over-think what the ideal profile is to receive maximum offers. Different companies and businesses look for different kind of consumers. For example, a soft drink company might want to hear more from teenagers whereas a formal apparel company might want to hear from the middle aged section. The demographics of the consumer also matter.
In a nutshell, the more the search companies you sign up with, the more offers you are likely to get qualified for. As your exposure to different research companies increases, so does the number of paid survey offers in your email. Therefore, the 2nd important step is to find the right research companies to sign up with. As already mentioned, different surveys reward the survey taker in different ways. Some offer cash whereas other offer free gifts, and enrolment in sweepstakes as well as free trials of consumer products like mobile phones and kitchen appliances.
When you sign up with a survey website, you instantly get access to a large database of paid surveys. This is your best bet and the best method for signing up with multiple research companies in the quickest time possible. Searching for them yourself is time-consuming. In addition, you will be in a better position to see what rewards are being offered for each survey. Otherwise you may end up wasting a lot of time signing up with businesses that do not offer what you are looking for.
