If you’ve never seen it, the Hubspot Academy, from the US-based sales and marketing software developer Hubspot, is a great place to learn fairly painlessly about a range of online marketing topics in exchange for just your email address. There are dozens of topics in marketing, sales and design, all freely available as a series of bite-sized videos.
