I just did an analysis of Q1 & Q2 and CPM’s in the UK are ~20% less than Canada/US and the UK converts VERY well. To give you an idea, last year Canada was ~20% less than US and UK. Guess everyone got distracted and focused on North America! This includes Ireland as well 🙂 So find some UK campaigns, there’s money to be made BIG TIME! Most popular verticals there were dating and health and beauty. Hope this helps!
