Businesses need to set and track metrics to understand how well they are performing in comparison with their competitors and the market average. This allows them to set realistic business benchmarks and goals and identify areas with room for improvement.

For online businesses, indicators like the average add-to-cart rate and average page views per visit in ecommerce are some of the most important metrics to keep an eye on. But those aren’t the only insightful ones. The average units per transaction metric can also provide an overview of the shopping habits and preferences of buyers.
