Doing paperwork, building web sites, answering email, and processing orders doesn't help grow your business - only advertising does.
Advertising is the lifeblood of any business.
If you do not learn how to advertise your products and services both efficiently and effectively, you won't be in business long. While the Internet has lessened or eliminated many of the costs normally associated with starting and running a small business, you'll never realize any significant profits if you don't grow your business through effective marketing. There are really just two kinds of advertising - that which you pay for and that which you get for free. And both should have their place in your overall marketing strategy. The problem arises if you do not understand how or when to use each.
