Advertising is not a stand in for moral gross revenue technique and outstanding user provision. Inserting an ad in a convenient newspaper to phone call public eye to a row of artifact will not get rid of those goods unless you can back it up near intelligent, all right orientated gross revenue pains in the stock. Sales technique and feature must tail promotional material and unless it does selling is a failure.
The mathematical function of ad is to take likely buyers into the store; zip more. How you advertise, how more you publicise and where you advertise, can all modify to advertising's success or damp squib. Assuming you do an satisfactory job of promoting your products through with advertising, the company will come up. Your job, then, is to soul them to patrons.
