Final answer:
The objective of keeping consumers thinking about the product is best achieved through reminder advertising, which maintains customer awareness and encourages brand loyalty.
Step-by-step explanation:
Keeping consumers thinking about the product is the objective of reminder advertising. This type of advertising is essential for products that have achieved a widespread level of market penetration and brand recognition. The goal is not to inform or persuade consumers who are unaware of the product, but rather to maintain customer awareness and reinforce the product's presence in the marketplace. It can be especially useful when a product faces seasonal demand fluctuations or increased competition. Companies use reminder advertising to encourage repeat purchases and brand loyalty among existing customers.
