I recently received an Amazon Local e-mail ad (similar to Groupon) for dental services. When I followed up here is what I found.
Notice on the right hand side. It says only 44 people bought the special. Is this good enough? I have heard of dental offices offering similar online Groupon specials having hundreds of responses. However this is the first I have personally investigated.
As much as I appreciate the potential power of social media as a marketing tool for dentists I am still waiting to see some actual case study results.
