Placing ideas or steering a guest toward products you think they will like is known as:

Suggestive selling refers specifically to the practice of guiding a guest or customer toward products or ideas that align with their interests or needs. This technique is particularly effective in enhancing customer satisfaction by helping them discover options they might not have initially considered, thereby enriching their overall experience. It is about providing tailored recommendations that resonate with the customer's preferences, leading to a more personalized shopping experience.

In contrast, upselling tends to focus more on encouraging customers to purchase a more expensive item or an upgrade of the original product they are considering, rather than on suggestion-based guidance. Steering might imply directing or guiding without the personalized recommendation aspect, and sharing is generally too vague and does not specifically relate to influencing purchasing decisions.
