I received HubSpot’s Inbound Marketing Certificate for proficiency in blogging, social media, lead conversion and nurturing, closed loop analysis. The online class was challenging but very well organized to cover many aspects of Inbound Marketing. My favorite lecture was of course David Meerman Scott’s class. Recommend taking the class–another one next week: Sign up at : http://www.inboundmarketing.com/university or join any of the Inbound Marketing Forums.
