The term, "getting found," refers to the notion that a business needs to be "found" on the Internet if consumers are to acknowledge it exists.
Of course, in reality, brick-and-mortar business still exist. However, those with a strong digital presence can enjoy additional (and necessary) layers of legitimacy and trust from patients, both preexisting and prospective, who have turned to the Internet to solve their health problems.
But don't just build a website and consider your work done. What you need is not only a website, but a strong web presence.
This is why "getting found" is so crucial. It's easy to fall for the Field of Dreams mentality: if you build it, they will come. This kind of magical thinking doesn't serve the more pragmatic concerns of a medical practice, however.
