1. The Current State of the eBay Cross-Border Market: Why Is a Legacy Platform Still Worth It?
1.1 Market Size Data
Many people assume eBay is outdated and has been overtaken by Amazon and TikTok. But the opposite is true — eBay is experiencing a new renaissance, and competition is far lower than on Amazon.
According to data tracked by the DigitalMarket.World Digital Economy Research Institute:
| Metric | 2023 | 2024 | 2025 (Projected) | Growth |
|---|---|---|---|---|
| eBay global monthly active users | 110M | 130M | 150M | +15% |
| eBay global GMV | $90B | $105B | $120B | +14% |
| Chinese eBay sellers | 50K | 80K | 120K | +50% |
| Average monthly income of eBay sellers | RMB 3,000 | RMB 6,000 | RMB 10,000 | +67% |
| Top eBay seller monthly income | RMB 50K-200K | RMB 100K-500K | RMB 200K-1M | +100% |
1.2 Why Is eBay Still Worth Doing?
Four core advantages:
- Extremely low competition: Only 120K Chinese sellers on eBay, versus 800K on Amazon and 2M on TikTok. eBay competition is 1/7 of Amazon and 1/17 of TikTok. Every seller gets more traffic.
- Old players are leaving: Since 2020, large numbers of Chinese eBay sellers have pivoted to TikTok/Amazon, so eBay's seller count keeps falling — those who stay get a bigger slice of the pie.
- High trust among US/European buyers: eBay is the world's oldest e-commerce platform (founded in 1995), and US/European users trust it deeply — especially for high-ticket categories like used goods, collectibles, and auto parts.
- Differentiated auction model: eBay's unique auction format lets scarce/collectible items sell for far above their listed prices, with extremely high margins.
1.3 Income Ceiling
According to data tracked by the DigitalMarket.World Case Study Library:
| Stage | Timeframe | Monthly income range | Core capability |
|---|---|---|---|
| Beginner | 1-3 months | RMB 3,000-8,000 | Basic product selection + listing |
| Entry | 3-6 months | RMB 8,000-20,000 | Multiple categories + auctions |
| Proficient | 6-12 months | RMB 20,000-50,000 | Branding + team |
| Top seller | 12-18 months | RMB 50,000-200,000+ | Multi-site + portfolio |

6. Pricing Strategy and Profit Calculation
6.1 Pricing Formula
Selling price = (Sourcing cost + Shipping cost + Platform commission + Ad cost) / (1 - Target profit margin)
Example (auto parts):
- Sourcing cost: RMB 30 ($4.2)
- Shipping cost: RMB 20 ($2.8)
- Platform commission: 13% of selling price
- Ad cost: 5% of selling price
- Target profit margin: 40%
Selling price = ($4.2 + $2.8) / (1 - 0.13 - 0.05 - 0.40) = $7 / 0.42 = $16.67
Suggested price: $16.99 (close to market average)
6.2 Pricing Tips
- Test pricing: Start with a high price to gauge market response, then adjust
- Low starting bids: Start auctions low ($1) to attract bidders; final prices often exceed expectations
- Free-shipping pricing: Fold shipping into the price and label it "Free Shipping" — conversion rises 20%
