Here’s an excellent piece of work which you can really lose yourself in. An A-Z of Marketing Terms on the Walker-Riley blog takes on 26 topics from the AIDA Marketing Model to the Zero Moment of Truth, visiting topics such as Content Marketing, KPIs and User Generated Content on the way. The authors have written a full post under every heading, and having spent a while on them myself, I can confirm they’re a good read. Take a look.
