Everybody knows you need a LASIK funnel. They're everywhere!
Here's the bad news - Funnels are required but insufficient.
Every funnel I see is a straight-through process starting with TOF (Top of Funnel) step where they first learn of your practice and what your LASIK patient experience is like. This is followed by the MOF (Middle of Funnel) step where they learn about your solutions and reputation and decide whether to keep shopping or not. Lastly they move into the BOF (Bottom of Funnel) step where they call or click and make an eval appointment.
There is something very mediocre about this approach. Read this detailed discussion of what you need to do instead of a one-size fits all LASIK funnel.
