Why category sales volume matters
Sales volume helps frame the possible scale of opportunity inside a niche.
It can be a strong early signal that the category is worth studying more closely.
Why size should not be used alone
A very large category can still be unattractive if pricing is weak or competition is deeply entrenched.
That is why the best category analysis always combines size with category quality.
