The Threshold Trials

The Threshold Trials

In line with the above test, some brands have have moved towards free shipping over a certain threshold to keep customers from finding another seller that does offer free shipping, as well as to increase AOV. If you're not already doing this, you could test a few different thresholds out, and if you do already have a threshold, you could test a higher and lower threshold (or a couple higher/lower) to try to find the sweet spot. Check out this case study on a brand who recently ran this type of test and found a ~6% increase in AOV and ~12% increase in revenue per site visitor!

What this test design might look like:

	Control Group	Lower Threshold	Higher Threshold	Highest Threshold
Threshold	$75	$50	$100	$125

We recommend taking a look at a histogram of your order values for the last month (or more) when deciding what thresholds to test. For example, if a majority of your orders come in around $90-$100, but your current threshold is $50, you may want to consider testing out a $100 threshold to push people to add one more item to their cart.
