Marketing is one of those things businesses know they need, but don't have the time to do.
Businesses see marketing as a merry-go-round needing constant attention, sucking up budget and producing lots of nice looking things which don't appear to drive sales.
Marketing isn't there to win awards, it's there to make sales!
There's no getting away from the fact that if marketing isn't generating enquiries and sales, it's failed. That's not to say that every action will result in a sale, that can take time, but every action should move customers through the sales funnel.
