Medical and doctor blogs have power. Just ask the med spa and laser clinic franchises that have suffered at the hands of the physicians who bought into them, and then related their experience on Medical Spa MD.
Here's a CNN story about blogs and the travel industry that dove tails with the growing number of plastic surgery, dermatology and skin clinic blogs that are integrated into existing sites.
In the near future, Medical Spa MD will be rolling out a laser clinc, medspa, and cosmetic practice blog network as well as detailed courses on SEO, gaining traffic, keyword analytics and general how to information. If you' don't already have a highly trafficed medical blog, that will be the time to start.
