Key Success Factors: The key to getting re-marketing right is to connect every piece of user behavior in real-time with a deep knowledge of the catalog of content (e.g. the catalog of jobs in the case of TheMuse, or the catalog of products in the case of UrbanLadder). The in-ability to connect this information in real-time can often block marketers from being able to send relevant re-marketing messages, or worse still, send out messages that have outdated content (e.g. sending an abandonment email after the customer has already purchased the item).
