When you are developing a marketing plan, you need to write a comprehensive solution to marketing. Advertising is a very important part of a marketing plan. One of the questions that should be asked is: what vehicles are you going to use for advertising - print media, digital media, radio, television? In the print media, the Yellow Pages is the first port of call for anyone who is looking for a business who can cater for an event or function. It therefore makes good business sense to advertise in the Yellow Pages.
