What does a sales funnel model describe?

A sales funnel model describes the stages of customer engagement from the moment they discover a product or service until they make a purchase. This model provides a visual representation of the customer's journey, indicating how potential customers move through different stages, typically categorized as awareness, interest, consideration, intent, evaluation, and purchase.

By understanding the sales funnel, marketers can tailor their strategies to nurture leads at each stage, ensuring that they provide the appropriate information and engagement needed to guide potential customers closer to making a purchase decision. This approach helps in optimizing marketing efforts, improving conversion rates, and ultimately driving sales.

In contrast, the other options suggest concepts that are not aligned with the comprehensive view of customer engagement encapsulated by the sales funnel. For instance, while one option mentions generating leads and another discusses advertising costs or customer retention strategies, those do not encompass the entire journey that a customer takes from initial awareness to final purchase completion, which is central to the sales funnel concept.
