- Who it helps
- Readers tracking consumer adoption and teams studying product demand.
- Availability
- The October 5 report is public. Its web, mobile and spending lists use different datasets and eligibility rules.
How it works
Web rankings use monthly visits, mobile rankings use monthly active users, and spending analysis uses a consumer panel. These measures have different denominators and should remain separate.
What to check for your task
Use a ranking to choose products to investigate. Then compare those products on a fixed task and check the measurement period before discussing growth.
