Five Marketplace Metrics Every Brand Should Track Weekly

Every brand on a marketplace tracks sales. Most track them daily, some hourly during events. But sales are a result, not a lever. By the time revenue moves, whatever caused it happened one to three weeks earlier. The brands that grow steadily are the ones watching the levers, weekly, in a fixed rhythm.

After nine years running weekly business reviews across Nykaa, Amazon, and multi-marketplace portfolios, these are the five numbers I put on every WBR, and what each one is actually telling you.

1. Availability — the sale you never see losing

Out-of-stock is invisible in a sales report. Revenue just quietly comes in lower, and everyone blames the season. Track in-stock rate on your top sellers weekly, because your best products go out of stock precisely when things are going well. On seasonal categories the stakes double: I ran women's winterwear at Nykaa, and a stock-out in week two of the season is revenue you cannot recover in week eight.

2. Buyability — listed is not the same as sellable

A product can be in stock and still unbuyable: suppressed listing, lost buy box, broken content, missing images, a price mismatch across channels. At Amazon, buyability was a first-class vendor metric for a reason — every unbuyable ASIN is shelf space you're paying for and not using. Count your unbuyable listings weekly. The number should be boring. When it isn't, that's the week's first conversation.

3. Traffic-to-conversion split — which problem do you actually have?

Flat sales hide two very different diseases. Falling traffic is a visibility problem: search rank, campaign coverage, category placement. Falling conversion with healthy traffic is a page problem: price, reviews, content, delivery promise. Brands waste entire quarters fixing the wrong one. Split the funnel weekly and the diagnosis takes five minutes instead of a month.

Sales tell you that something happened. Traffic and conversion tell you what.

4. Price position — because the market moved on Tuesday

Your price didn't change; your competitiveness did. A competitor ran a coupon, a marketplace event pulled the category down, a reseller undercut your D2C site. Weekly price-position tracking on your hero SKUs, against your true competitor set rather than your aspirational one, is the difference between deciding your discounting and having it decided for you.

5. Contribution margin — growth you get to keep

Revenue growth that arrives entirely through discounts and ad spend isn't growth; it's a purchase. Look at contribution margin weekly, even roughly, so promotional decisions carry their real cost. The discipline matters most during events, when the pressure to buy revenue is highest. A category that grows 40% profitably is a business; one that grows 40% at any cost is a countdown.

The rhythm matters more than the dashboard

None of these metrics is exotic. The value isn't in the numbers — it's in reviewing the same five, every week, with the same people, and turning every red cell into an owner and a date. That rhythm is what a weekly business review actually builds: not a report, but a habit of catching problems while they're still cheap.

Start with these five. Add a sixth only when one of the first five has been green for a quarter.
