Gaining customer reviews is an essential part in the success of your venture, and without the proper approach and maintenance, these reviews can dwindle over time.
The customer should not feel like they are burdened by your approach; leaving a business card with a review site URL inside a parcel has more likelihood of ending up in the trash than it will convert into a review. Even if the customer does see the URL on the card, what entices them into typing a link into their browser and leaving a review on a website?
Businesses are becoming savvier, asking and managing reviews using a dedicated system that can email, send SMS and even pop up on their websites if a customer returns with an account. By finding a way to contact the consumer in an unobtrusive way, they may be more inclined to review your product or service, especially if you make it easy for them to do so.
