Sixty percent of consumers conduct online research before going to a business’ website to weigh a purchase decision. Even if you have a new top-of-the-line site, people may never make it there if they don’t like what they see on popular review sites. Consumers don’t know you, so all they have to go by is what they find online.
Some good advice starting with a mobile friendly website. The linked article also discusses social media. I am much more skeptical of the value of social media for a dentist. The only ones I believe really matter are review sites.
What I recommend instead of spending time and money on Facebook is to develop a website that supports existing patients with online bill pay and interactive forms.
