Which of the following mediums are part of the purchase funnel?

The purchase funnel represents the stages that a consumer goes through from awareness to decision-making and ultimately to purchase. The correct choice aligns with mediums that are integral to driving consumers at various stages of this funnel.

Online video, search, display, and social media are all digital platforms that play a crucial role in connecting with potential customers. Online video can create strong brand awareness and engagement, enticing viewers and guiding them into the consideration phase. Search advertising captures intent as consumers are actively looking for solutions or products, making it a powerful tool in the decision-making process. Display ads work to remind or inform consumers throughout their journey, and social media not only aids in awareness but also fosters engagement and community, influencing decisions and driving conversions.

In contrast, the other options consist primarily of traditional advertising methods that, while effective, do not encapsulate the same level of targeting and measurable engagement with consumers throughout the purchase process as the digital options do. Therefore, option A is the most comprehensive and aligned with the dynamics of the modern purchase funnel.
