These days I dug more into the new G4 Analytics to learn how to implement it for one of the big websites I work for. Here’s what I learned:
I started with the video training provided on demand by a Google Account Strategist, but it was packed with so many details that I need. The most simple & explicit tutorial I found on
Following these materials, here’s what I learned:
- GA3 & GA4 Analytics are totally different and G3 data can’t be imported into the new G4;
- If I use the GA4 Assistant, it creates a new property that is not connected to the old GA3;
- Instead of using GA4 Assistant, it is recommended to create a new property;
- use the same container of Google Tag Manager for both old GA3 & new GA4;
- There are a few basic settings after creating the new GA4 property:
- change data retention from 2 months to 14 months;
- import the domain on the Unwanted referrals list;
- cross-domain tracking if needed (GA4 is available for subdomains, along with the main domain).
- Checking Google Signals (Data Settings – Data Collections) is not useful for a website with small traffic, since thresholding may be applied if there are not enough total users.
