How do online surveys help companies?

Online surveys help companies in a variety of ways. For one, they provide an extra amount of exposure for their company. If a company pays you to fill out an online survey, chances are that you will tell people about the company in a positive way.
Online surveys are also a way to give companies an idea of what their target audience wants and needs. By providing honest answers, companies can gear their services or merchandise towards their target demographic and, as a result, increase the amount of revenue they bring in. If a company needs improvement in a certain area, online surveys can also help companies recognize and fix the problems.
