Marketers have a huge blind spot when it comes to nurturing and lead scoring. It does not matter if you have built a sophisticated lead management and nurturing system, driven by content consumption, engagement and response. Your blind spot is there.
The problem is, you only see how people respond to your content and your offers. You only see what is happening on your own properties. Your blind spot is all the time potential prospects spend on competitor sites, on editorial properties, on topical blogs or discussing with peers.
