It's not just google analytics data. You can also connect to:
- Attribution 360 (no idea what that is)
- Cloud SQL
- Google Sheets
- YouTube Analytics
Google sheets is really interesting. You can use the google scripts function in google sheets to write ETL and it actually has a scheduling functionality. So you can run it every X mins. That's a free, cloud based, scheduled BI tool right there.
You can also push data into google sheets from Zapier. The free plan on Zapier is enough to do some really great things.
