advertising! is crucial

I grew up in a village and because unemployment affects all of us in the country some individuals in my village start businesses in order to survive and make a living.Sadly what i have noticed is that most time these individuals don't allocate time and resources to advertise their business,so if a person does not walk or pass by the sides of the village where the business "happens to be at" that person wouldn't that the business existed which actually leads to the business not growing and not being profitable. so my advice to small business owners advertise! advertise! advertise!
