Today, there was a Tweet about event parameters in Google Analytics 4:
That tweet links to an Analytics Help page, titled, [GA4] About Event Parameters.
With parameters, you can add an entire range (up to 25) of pieces of metadata to each event. That’s certainly a lot, and it’s hard to fathom how any business might need to use that many for a single event. Regardless, this number gives you a lot of flexibility and capability.
There are many, many things you can do with Google Analytics, such as tech reports. I wrote an article on the subject here: Tech Reports in Google Analytics for App Development.
Do you know about data freshness? Google Document on Data Freshness for Google Analytics.
Do you want to track visitors? How to Track Website Visitors Using Google Analytics.
My article, How to Use Google Analytics 4’s Segmentation Feature, is about exactly that: using the segmentation feature.
Also, you can learn, How to Measure Customer Acquisition With Google Analytics.
As a side note, Google Analytics can also work well with other Google services. This is generally called blended data, and I wrote about it here: Google Data Studio: Google Tweets New Article on Blended Data Sources.
