Remember the days when people looked in the hardcopy yellow pages for businesses or services they needed? Advertising a company in the yellow pages was very profitable. For many people, those days are still here. However, there has been a shift taking place in recent years to online web business directories. Listing with an online business directory is a good, inexpensive way to gain exposure for a company. Often the cost is less than that of advertising in the traditional paper yellow pages. With traditional paper business directories, once they are printed, corrections, changes, and additions cannot be made until the new edition is released. With online business directories, you can make these important changes any time.
