Public relations:

☛ 1. Your job profile is to get free publicity for the company and also promote their products and services.

☛ 2. You don't have any control on media over how the media will present your information as they are not obligated to do so.

☛ 3. The PR exposure you receive is only circulated once. An editor won't publish your same press release three or four times in their magazine.

☛ 4. A third-party article written about your product or service is read by the customer assuming that you are not paid to write positive things about the product.

Advertising:

☛ 1. Here you are paid for the ad space and you know exactly when that ad will be aired or published.

☛ 2. You have paid for the space so you have a creative control on what goes into that ad.

☛ 3. Since you pay for the space, you can run your ads over and over for as long as your budget allows.

☛ 4. Consumers know when they're reading an advertisement they're trying to sell a product or service.
