This guide assumes you've got GA4 set up... you just don't know what to do with it!
Lots of screenshots and easy to understand text explains to you what terms mean in GA4 (especially important when they're different to old GA!), and help you find your way around the interfaces.
It then walks you through how to do the 3 key reports anyone using GA4 needs to understand:
1. Where do people come from?
2. Which pages do people visit the most?
3. Which pages do people enter the site from?
