I’ve been tracking Pinterest for a while now and, to me, the single most important aspect of the site is that it has deeply tapped into an important shift in consumer and purchasing behavior. As we make a decision to search for or buy something online, we are trained to go to Google (or Amazon), search by keyword, and sort through results to eventually make a transaction. In return for that sorting, Google charges for advertising, but in order for it to work, we users have to signal our intent: “Red Nike running sneakers.” But, how did I decide to want these red running shoes in the first place? While Google makes money at the bottom of this decision funnel, the top of the funnel is where “discovery” happens. It’s much wider at the top of the funnel, and harder to pin down where the thoughts originate (pun intended).
