Yariv Drori outlines 7 rules for effective digital display advertising campaigns for B2B companies. The rules are: 1) The buying journey has shifted online so digital ads are important. 2) Data allows for highly targeted ads tailored to audiences' interests and stage in the buying process. 3) The buying journey has changed permanently so marketing budgets must also change. 4) Data helps build and optimize effective ads. 5) Programmatic advertising allows efficient use of funds. 6) Ads must overcome "banner blindness" with compelling visual design and messaging. 7) Creativity now differentiates B2B marketing from boring ads of the past.
