This was a quick study I designed to gauge the influence of coupons on local business listings across business categories. A poll was presented to site visitors who viewed a business profile page on a local search site that contained a coupon as well as business profile page that did not. The poll was presented one time to site visitors and submitted the business category of the given business.
The North American Industry Classification system was used to cluster the results across top viewed categories.
The results of the study indicate the presence of a coupon would increase the likelihood a site visitor would contact businesses in the Accommodation & Food Services, Retail Trade Products, Healthcare & Social Assistance and Service categories.
