We invest in an ongoing programme of research. It informs our content and events so you can be sure they are grounded in real data and the latest findings. Every year at EffWeek we publish our new findings. We focus our efforts on four areas: the impact of digital on media investments, building effectiveness culture, creativity, and measurement.


"Forget the hype, forget the misreporting. We are seeking to represent what’s really going on and the opportunities for improvement in our industry. EffWeek and EffWorks are not just about what we do, but why and how we do it. Our overall ambition is to encourage evidence-based decision making in marketing. To move the industry from a reporting to a learning culture. To encourage greater accountability and transparency. Ultimately to create more value for the brands we service."
