B2B buyers expect relevant and responsive interactions with sellers to support them throughout increasingly complex buying scenarios.

The Forrester B2B Contextualization Cycle provides a repeatable methodology that allows marketers to sense and respond to buying signals with best-fit content and delivery by connecting content and data sources across systems, processes, and buying interactions.
