This document discusses how marketers can use context to personalize customer experiences across the sales funnel. It outlines a three-step process: 1) Gather information about customers from all touchpoints to build a 360-degree view of who they are and what interests them, 2) Personalize the experience based on that information through personalized content, lead nurturing, websites, landing pages and social media, and 3) Use the context gathered to better sell to customers by monitoring their activities and engaging with them directly. The goal is to move from treating customers as part of a crowd to speaking to each individual customer as an "audience of one."
