Here is a truth bomb: most marketers cannot explain what a “session ID” actually is, yet we base half our KPIs on sessions. I was guilty too until I had to debug a massive discrepancy between GA4 and our internal warehouse. Learning the underlying data model – how GA4 processes hits into sessions, how timestamps work, what resets a session – changed everything. The best resource I found doesn't sell a course or a tool; it just defines 71 terms including sessionization logic, engagement time, and scroll depth. After you read the ga4 glossary https://accs-net.com/glossary/ you will never look at a session count the same way. And you will finally win arguments with your data engineer.
