Avoid wastage of money is not an objective of advertising research.

The objectives of advertising research are:

A. Improve the efficiency of an ad: Advertising research can help to determine which elements of an advertisement are most effective in terms of capturing the attention of the target audience and promoting the desired response.

B. Develop advertising plans: Advertising research can provide important information that can be used to inform the development of advertising plans, including determining the target audience, selecting the most effective media channels, and determining the best messages to use.

C. Evaluate impact of an ad: Advertising research can be used to evaluate the impact of an advertisement on the target audience, including measuring changes in attitudes, behaviors, or sales.

While avoiding wastage of money is certainly an important consideration for any business, it is not specifically an objective of advertising research.
