The bottom line is whether it brought in additional customers and/or revenue. Was the increased business enough to cover the cost of purchasing the items? It is imperative that you monitor the effectiveness of the promotional product campaign to gauge its effectiveness. If the campaign does not produce the desired result, then the money spent on the products was a bad business expense. If the campaign does produce the desired result, it would be a good idea to continue it.
A good way to check the effectiveness of a promotional product campaign is to ask customers as they make their purchases how they heard of your business. Many companies are attaching customer surveys to the bottom of cash register receipts. These surveys ask the customer to call a toll-free number or visit a website and give their opinions about that particular transaction. A computer tabulates the results for the survey and results are faxed or emailed to the company.
If you are talking to the customer in person, ask them why they chose to do business with your company rather than one of your competitors. Their answers will indicate whether a current promotion is working. If not, the information they give may show the way to a promotional product or advertising campaign that will be more effective in the future. Listen to your customers to find out what brings them back. Let them know they are important to your business and they will remain loyal customers for some time.
