Marketing is not advertising.
Product, Place, Price, Promotion, People, Physical Proof, Process.
Advertising focuses on the “promotion” part of the 7Ps.
The advertising part would be: The billboards you see or the ads on television
The marketing would be: The Store location, customer service, packaging of the chicken, pricing of items on the menu, the extended product line like the sauces etc
If you have further questions & I don’t answer them, that will be because the answer to your question is in the thread I’ve just posted. Goodluck. Happy Learning🙌🏾
