What is week-over-week growth?
Week-over-week (WoW) growth compares a metric’s value in the current week to its value in the prior week, a common way to track short-term trends in sales, traffic, or usage.
The formula
WoW % Change = [(This Week − Last Week) / Last Week] × 100. A positive result indicates growth from the prior week; a negative result indicates a decline.
