The document summarizes findings from a 2012 study on B2B digital marketing and buyer behavior. It discusses four key themes: 1) Relationship building was the top objective for marketers but they may not be effective, 2) Thought leadership is important but impact is unclear, 3) Understanding effective channels is a challenge, 4) Gaps exist between marketer spending and buyer preferences. The study found that prospective suppliers contact buyers more through personalized email and events work best to positively influence buyers. However, marketers spend little on relationship-building tools like extranets.
