GA4 is introducing Source Group, improving Source Platform, and adding a new Hostname filter.
Source Group standardizes messy source values such as “fb,” “facebook,” and “Meta-facebook” into one clear reporting value.
This makes cross-channel performance, attribution, and budget analysis easier across platforms like Meta, TikTok, Pinterest, Amazon, Google, ChatGPT, and Perplexity.
The new Hostname filter also lets you exclude events from unapproved domains, helping keep your data clean and relevant.
