Since Google loves unique content, somebody is going to have to custom write this site if you care about dental SEO. A good dental marketing company will interview you and write it for you. Some doctors want to write it themselves, but if they’re not familiar with the nuances of dental SEO, they could easily compromise their site rank. Google loves to read a good 300-500 words per page (at a minimum) so it’s also going to take a lot longer than you think. If you want to try this solo, remember to write from the patient point of view, and write at an 8-10th grade reading level to be as palatable as possible to the average visitor.
