Google Data Studio is great for reporting on data from a variety of sources.
Depending on how you currently measure performance there are many data connectors that may be suitable for an ecommerce site. For example, there are connectors available for Google Analytics, SQL databases, Google Sheets etc. There is even an option to upload data directly from a file.
With over 630 data connectors available we’d recommend first reviewing which would be most suitable for your business data.
Once you have found an appropriate data connection you can choose to build a report from scratch or use one of the templates from Google’s Report Gallery.
