What is the difference between advertising and personal selling?

Advertising can control the amount of wasted coverage, whereas personal selling cannot control the amount of wasted coverage.

Advertising uses customized interaction between sellers and potential consumers, whereas personal selling sells to a large group of potential consumers.

Advertising is always a paid activity to sell a product, whereas personal selling involves no direct payment to sellers.

Advertising does not have an immediate feedback loop, whereas personal selling does because of direct interaction with potential consumers.
