Top eCommerce products in a country - GA4 BigQuery

Learn to query Google Analytics 4 data from BigQuery using SQL.

With Google Analytics 4 (GA4), you will now be able to store your data in Google BigQuery which opens up lots of interesting possibilities with your data. Ask questions of your data with SQL.

Query: What are the top eCommerce products in a given country?

I used the United States as an example in this query.

select
items.item_name as item_name,
sum(ecommerce.total_item_quantity) as purchases
from `bigquery-public-data.ga4_obfuscated_sample_ecommerce.events_*`,
unnest(items) as items
where _TABLE_SUFFIX between '20210101' and '20210107'
and event_name = 'purchase'
and geo.country = 'United States'
group by item_name
order by purchases desc
limit 10

Output:

Dimensions

  • items.item_name -> product

Metrics

  • ecommerce.total_item_quantity -> purchases

Notes:

  • All queries reference the BigQuery sample GA4 data set. You can try this for free and Google provides a substantial free credit.
  • The dataset contains data from 1 Nov 2020 to 31 Jan 2021.
  • You will need to update the data source if you want to use this query with your own data.
  • You can update the date range to suit your needs. I have chosen 1 Jan 2021 to 7 Jan 2021 for this example.
  • Occasionally the results may not line up perfectly when querying this sample dataset.
