Ad-effectiveness using a communication Objective is not sufficient in Itself: - Some advertisement may perhaps achieve communication objectives however may not promote sales. Some advertisement may be extremely attractive well remembered entertaining and liked buy many viewers/ audience but still it perhaps ineffective in generating additional sales, These advertisement perhaps well recalled because of attractive modals simple to remembered phrases homeruns appeal etc. However viewers still mayn't be buying the product for the reason that they have no liking that product. For example Advertisement of bagpiper with Sunny Deol as model is remembered by many viewers for the reason that its model is attractive. However still all such viewers don't buy bagpiper products therefore measuring ad-effectiveness only on the bases on the bases of communication objectives isn't sufficient in itself.
