Over 75% of total UK ad spend in the UK was allocated to digital channels and as they continue to dominate UK marketing budgets, the pressure on brands to prove that measurable impact has never been greater.
Yet, for many, traditional measurement models feel fragmented, overwhelming, and resource-heavy, often raising more questions than answers. Planning campaigns and dividing budgets between “what’s working” feels more complex than ever.
This event is designed to cut through the complexity and give you a clear, practical path to building an effective digital marketing plan that delivers for your business. Whether you’re a well-established brand looking to optimise your spend, or a fast-growing challenger seeking to scale smartly, this session will equip you with the tools and insights to drive real results.
Through practical frameworks, and real-world case studies, you’ll explore how to:
- Build a fit-for-purpose measurement approach tailored to your organisation
- Use experimentation and evidence-based planning to fuel smarter decision-making
- Create a flexible, scalable effectiveness toolkit that adapts as you grow
What you’ll learn:
Talk one – The media measurement gap and how to close it, with Aaron Dicks, Technology Director at Impression
- Unpack the media measurement gap

Talk two – Evidence into Action – How to use marketing effectiveness outputs to power your plan, with Claire Elsworth, Strategy Director at Impression
