(c) Ilesh Persand and Joana Esgalhado, Friends of the Earth UK - https://friendsoftheearth.uk/ Small changes to your digital communications can have a big impact - constantly testing, comparing and improving is vital. But how do you decide what to test, interpret and keep track of the results and make sure you're consistently learning and implementing improvements? Joana and Ilesh will talk through the testing programme at Friends of the Earth England, Wales and Northern Ireland, sharing some results, and help you work through the tools, resources and approaches you need to implement a testing programme that will have real impact on the performance of your digital comms.
