Reading a supplier catalog like a competitor analyst

Stop importing what everyone else imported last quarter.

Reading a supplier catalog like a competitor analyst

5 signals that a SKU is already saturated before you order.

When a supplier sends you a catalog of 4,000 SKUs, the natural instinct is to filter by margin and order the top 200. That's how every other seller does it — which is exactly why those 200 SKUs are unprofitable by the time your first container lands.

The 5 saturation signals

  1. 1

    More than 12 active sellers in the first 3 search pages

    If you're seller #13 on day one, your buy box share starts below 8%. Avoid.

  2. 2

    Lowest price within 4% of your landed cost

    The race to the bottom already happened. You're entering at the floor.

  3. 3

    Top sellers have >500 reviews on the listing

    You'd need 18+ months of sales velocity to catch up. Skip.

  4. 4

    Title keyword stuffing across competitors

    When everyone uses the same 8 keywords, the category is mature. New entrants don't get clicks.

  5. 5

    Price has been flat for 90+ days

    A flat price means the market has settled. There's no pricing power left to capture.

Saturated SKU profile

  • 12+ sellers
  • <6% margin floor
  • Flat price 90 days
  • 500+ review competitors

Open lane SKU profile

  • + 1–4 sellers
  • + 20%+ margin
  • + Price volatility 10%+
  • + <50 review leaders

Use this filter on every catalog before you place an order. You'll cut your shortlist by 80% — and the 20% that remains will outperform everything else by 3x.
