Density, which is genetically linked, deals with the number of strands per square inch on your scalp. Normal density can range from slight to substantial, varying from person to person.

It is vital to use proper keyword density because if your density is too low, your SERP's ranking decreases.

Let's say you get a new customer across town and you don't have any other customers over there. You still need to be competitive with price, but it costs too much money to send crews or a serviceman to one account across town.
