Many Multi-national marketing companies are ready to spend billions of dollars to research about their new products and services by conducting online surveys. So they will look for Online Survey companies to conduct surveys on their behalf. These Survey companies are a website with large community of member database from all around the world to conduct surveys for MNC companies.
Marketing companies will pay to these survey companies for conducting surveys and these survey companies after getting order signed, will select members from their database and send invitation via mail to attend surveys.
We will receive invitation only if our profile matches with the requirements of the survey company. This method saves a lot of money in terms of advertisements to those Multi-national marketing companies and hence they use that money to pay us via survey companies.
