Frequently Asked Questions
What counts toward "category size"?
It includes total revenue, unit volume, and the count of active brands and products within the category as defined on Amazon, not just top-line sales for a handful of leaders.
Can this size a brand-new product concept that doesn't have a category yet?
Yes. You can size the closest existing category as a proxy, or size a narrower niche within it, to estimate opportunity before a concept exists.
How current is the growth rate?
Growth is typically shown year-over-year using the most recent trailing period available, so it reflects recent momentum rather than a single snapshot in time.
