Product or service surveys: Before the invention of the internet, it was so difficult to conduct a survey, most companies would pay money to magazines and place survey forms and offer gifts to users who filled those surveys and mailed them back to the company. Taking a survey is very important to a business, because that is how you will know what your clients want and know areas of improvement. Now days, a business can conduct a survey using social networks and provide users with incentives like ‘’gift cards’’. This produces quick response and saves the company money and time.
