At a glance
Your revenue concentration, ranked. The ASINs that generated the most ordered product sales in the period, biggest first. This is the card that tells an owner or marketing lead where the money actually comes from, and how exposed the business is if one or two hero products stumble. It is the natural starting point for prioritising Buy Box defence, stock cover, ad budget, and listing-quality work, because effort on a top-revenue ASIN moves the whole P&L.

A UK supplements brand on FBA. Period: 01 Apr 26 to 30 Apr 26 (30D).- The business lives on three ASINs. Two thirds of revenue comes from the top three. That is concentration risk: a Buy Box loss, suppression, or stockout on the multivitamin alone puts more than a third of revenue at stake. These three ASINs should have the tightest Buy Box monitoring and the deepest stock cover.
- High revenue is not high margin. This card is gross. The probiotic at rank five might out-earn the multivitamin per unit after fees if its referral category or FBA size tier is kinder. Pair with Fees % of Revenue and Net Revenue (after fees + refunds) before deciding where margin lives.
- Defend the leaders before chasing the tail. A 1% Buy Box improvement on the £41,200 multivitamin is worth more than doubling a long-tail ASIN. Prioritise Buy-Box Win Rate (top-50 ASINs) and stock cover on the leaders.
