Wish: Can Cheap Go Global?

📅 November 2025 · ⏱️ 8 min read

Objective

This project analyzes Wish, a global e-commerce platform, through its summer 2020 product catalogue. The main goal is to understand whether Wish’s low-price strategy really pays off, how trustworthy the platform is, and whether it still needs additional advertising to grow.

Dataset

The dataset contains summer products sold on Wish in August 2020, including product information, prices, ratings, shipping coverage and advertising flags.

📊 Source: Wish Summer Products 2020 dataset (Kaggle)

📝 Records: ~1,500 products

🛠 Tools: SQL (data preparation) & Power BI (visual analysis)

Using Python, I first checked for missing values and removed several columns with more than 90% nulls (for example urgency banners and profile pictures). Then I created new features such as:

  • Price ranges (1–10 €, 11–20 €, 21–30 €, 31–49 €, 50+ €)
  • Product categories based on keywords in the description
  • Shipping reach (niche, popular, mainstream, global) based on number of countries
  • Categorical versions of boolean fields like uses_ads_boosts and shipping_is_express

Main Insights

  • Low prices drive massive volume. Products in the 1–10 € price range generated over 5 million units sold, making this the most profitable tier in absolute terms.
  • Trust is built through reviews, not perfection. None of the top merchants reached a perfect 5/5 rating, but several achieved very high scores backed by 100+ reviews, which indicates a generally reliable marketplace.
  • Price ≠ quality, but it helps. Higher-priced products tend to receive better ratings on average, but the cheapest items still perform surprisingly well, coming close to mid-range products in terms of customer satisfaction.
  • Global reach with a long tail of niche products. Products are shipped to between 6 and 140 countries. Even though only a small group is truly “global” (100+ countries), niche and popular items also achieve strong sales.
  • Limited impact of ads. Only a small share of products use ads, and they do not show a clear advantage in either ratings or units sold, suggesting that advertising brings limited additional value in this snapshot of the platform.

Conclusions

The analysis was guided by three key questions: Is Wish’s low-price strategy effective?, Can the platform be trusted?, and Does it still need more advertising?

The results show that the low-price strategy clearly works: most sales happen in the lowest price range, and customers are still fairly satisfied with these products. When it comes to trust, merchants with many reviews and good ratings provide a solid signal for buyers, even if no one reaches a perfect score.

Finally, the platform appears to have already achieved strong global reach. Products are shipped worldwide, and advertising does not seem to significantly change performance in this dataset. This suggests that Wish is already in a mature stage, where organic visibility and price positioning play a bigger role than paid promotion.

Next Steps: a natural extension of this project would be to add predictive models for demand, or to build customer and product segments to support more targeted strategies.

Recommendations

  • Expand express shipping to regions outside China to improve delivery speed and user experience.
  • Diversify product origins to include more non-Chinese manufacturers and increase perceived quality and trust.
  • Introduce local warehouses in major regions (e.g. Europe, North America) to reduce shipping times and costs.
  • Add clearer product categories instead of relying only on keyword search, improving navigation for new users.
