What is Intent-Based Marketing?
Intent-based marketing is a strategy that identifies and targets prospects based on their active digital behaviors, indicating they are in-market to buy. By tracking signals such as whitepaper downloads, search queries, and website visits, sales teams can prioritize accounts showing high purchase intent. This approach helps companies focus their marketing and sales resources on the prospects most likely to convert, rather than wasting effort on cold, unresponsive lists.
