Many restaurants say marketing doesn't work. They try one thing, then they try another, and nothing seems to deliver any results.
But that's the problem. When you keep doing one thing, stopping, then switching to another, any of the traction you may have created from the first thing is now lost.
Instead, look at them as building blocks. Do one thing, create a process for it, manage the process, then add the next thing.
The inclusive return of putting the blocks together will always be more than the return of the single individual blocks.
