A major selling idea should emerge as the strongest singular thing you can say about your product or service and should stand strong enough to remain the central issue in every ad and commercial in the campaign. True or false?

False.

Explanation:

Every good advertisement should contain the following

(1) It Should Be Easy To Understand

(2) It Should Be Able To Catch The Attention Of Intended Audience.

(3) It Must Be Able to Convince The Intended Audience.

(4) It Has To Be Educational.

(5) It Should Be Easily Remembered.

(6) It Must Be Unique.

While you should strive to push forward a main central idea about your product or service, not having another minor hooking line in advertisement, could lead to unnecessary repetitions and to the intended audience, it feels as if such product or service is forced down their throat and this could lead to rejection by a number of the target audience.
