Why your sales changed, product by product

Why sales changed compares the last 14 days with the 14 before (28 and 28 when your products sell few units each) and splits the revenue change into four parts that add up: visits, buyers per visit, price on the same products, and product mix. Then it lists each product that sold less with its likely causes and the part of the drop each one explains.

Why sales went up or down: visits, buyers per visit, price and mix, then the cause per product.

  • Four parts that add up to the change: visits, buyers per visit, price, mix
  • Per product: days it could not be bought, Buy Box, visits, conversion, price
  • Drops that chance explains are listed apart and not counted
  • Read-only: it changes nothing and never suggests a price

How it works

  1. Pick the period

    The last 14 days against the 14 before by default, or any period from 7 to 45 days. Stores whose products sell few units each get 28 and 28, so chance does not look like a cause.

  2. The change is split

    Revenue change = fewer or more visits + fewer or more buyers per visit + price on the same products + a different product mix. The parts add up to the change.

  3. Each product gets its causes

    Days it could not be bought (out of stock, listing not buyable in Amazon's own status, no offer shown that day), Buy Box lost or hidden, fewer visits or ad clicks, fewer buyers per visit (rating, critical reviews, a promotion that ended), lower price per unit. Each cause shows the part of the drop it explains, never more than the drop.

  4. Normal ups and downs are set apart

    A drop that chance explains (few units against the visits), or that another variation of the same product made up, is listed separately and not counted.

  5. Open one product

    Day by day: what changed and when (your listing, price and campaign changes, stock-outs, status, Buy Box, promotions, reviews), its searches from Brand Analytics, organic rank, the variation family, and what Amazon says about it now.

Products that sold more, and opportunities

Products that sold more say why. Products with an opportunity are flagged: the Buy Box held but few views, conversion far below the rest of the store, or no ads at all.

Where the numbers come from

Your orders, Amazon's Sales & Traffic report (sessions, conversion, Buy Box per day), FBA inventory, listing status and issues, your advertising reports, reviews, promotions and Brand Analytics where your account has it. A live read of the Buy Box and listing status is available for the products shown.

What it does not do

Stated plainly, so you know before you start.

  • It does not change anything on Amazon
  • It never suggests a price change
  • It does not count a drop that chance explains as a cause
  • It cannot see traffic Amazon does not report, such as other sellers' visits

Questions sellers ask

How is the drop split?
Into visits, buyers per visit, price on the same products and product mix. The four parts add up to the revenue change, so you see which one moved.
What if only one variation dropped?
If another variation of the same product made up the loss, the drop is listed as a normal up and down and not counted.
Can I ask it in plain words?
Yes. Ask SellerPilot AI, in the app or in Claude or ChatGPT, why sales changed; it uses the same analysis.
