I get it, marketing is frustrating.  It's not fast, it can be unpredictable and even with modern analytics it can be difficult to measure.

What I can tell you is that if you don't put together a marketing strategy, you are as good as hiding.  If your website isn't mobile friendly and optimized, it can been like finding a needle in a haystack on Google.  Yes, people can type your business name in, but what if people don't know your name or they misspell your business name? Then what?
