Short answer
The dark funnel is the untrackable part of a B2B buyer's research, such as peer chats, podcasts, communities and social media, that attribution tools miss. Buyers often form preferences long before filling out a form. Marketers address it by asking prospects how they heard about the company and investing in brand and community presence.
