7 Data Points You Must Check Before Sourcing on Coupang
Source by gut and you get dead stock.
Source by data and you get revenue.
"This seems like it would sell well, right?"
Too many sellers still make sourcing decisions with this one line.
But that 'seems like' is usually wrong.
After analyzing thousands of products, we confirmed one thing: successful sourcing sellers always check specific data before committing.
Here's their checklist.
01Competitor's Actual Sales Volume (28-Day Basis)
Guessing sales from review counts is a thing of the past. A product with 200 reviews might sell 130 or 1,400 units per month. Without verifying the actual 28-day sales volume, your sourcing starts on the wrong foot.

02Category Average Conversion Rate
Conversion rates vary by category. Pets average 3–4.5%, while Fashion averages 1–2%. Without knowing the conversion rate benchmark for your target category, you'll keep wondering 'Why isn't this selling?' even with a great product.
With the same revenue, categories with higher conversion rates are dramatically more ad-efficient.
03Competitor Review Count & Growth Rate
Review growth rate matters more than the total count. 500 reviews but only 3 new ones last month? That product has peaked. But 50 reviews gaining 20 per month? That's likely a rising star.
Review growth rate = the market's temperature. It's the key indicator for whether a product is heating up or cooling down.
04Sales Distribution by Price Range
Within the same category, sales volumes differ completely by price range. Products that sell well at $10 vs $30 attract buyers with very different expectations. First understand which price range your cost structure allows you to compete in.
Comparing competitors' prices and sales volumes simultaneously reveals the ideal 'entry price range.'
05Seasonality & Trend Data
Sourcing fans in December? Obviously a no-go. But subtler seasonality is easy to miss. Products like humidifier filters, graduation gifts, and camping gear spike 3–5x during specific periods then drop sharply.
Cross-reference Google Trends with Coupang sales data to time your sourcing perfectly.
06Expected ROAS (Return on Ad Spend)
New products on Coupang almost never rank organically without ads. The problem? Many sellers spend on ads only to break even. Before sourcing, reverse-calculate your ROAS using expected CPC, conversion rate, and margin.
Products that can't achieve 300%+ ROAS are unlikely to be profitable even with heavy ad spend.
07Margin Simulation (Including Worst Case)
Factor in COGS, Coupang fees, logistics, and return rates to calculate net margin. Many sellers start thinking 'roughly 30% margin' only to discover they're left with under 8%. Simulate both 5% and 15% return rate scenarios.
Only source products that maintain 10%+ net margin even in worst-case scenarios. That's the survival threshold.
Only source products that pass the checklist
If a product can't pass at least 5 out of 7 checks, don't source it.
You'd be surprised how many 'sure things' fail after going through these 7 checks.
Conversely, products you dismissed might turn out to be opportunities when viewed through data.
Don't trust feelings. Trust numbers.
