Use best seller movement as a category clue
Best seller changes help teams understand which products may be gaining traction or losing momentum.
That makes them useful for broader competitive analysis rather than just leaderboard watching.

A single best seller change may not matter much on its own.
Patterns across time help show whether the category is truly shifting or just seeing short-term noise.
