I have a Facebook page for my practice separate from my personal FB page. There are over 200 people who like and follow. I post updates about the practice and new services offered, etc, on there. I think it increases your marketing. In the past I paid to promote the site with FB, and I don't think it did much. I have spent thousands on the newspaper, and I think it did nothing! I have continued a yellow pages ad that gets just a few people per year. I think the website is important, as young people google for doctors. Word of mouth remains the most important marketing.
