In the fast-evolving digital economy, the Online-to-Offline (O2O) business model has become a cornerstone of modern commerce. Platforms like Meituan connect consumers with local services—from dining and entertainment to retail and wellness—by driving online engagement toward physical consumption. A key strategy in this ecosystem is the use of digital coupons, which serve as powerful tools for customer acquisition, retention, and sales stimulation. However, indiscriminate coupon distribution can lead to user annoyance, brand dilution, and inflated marketing costs.
This article explores how machine learning, particularly the XGBoost algorithm, enables merchants on platforms like Meituan to shift from random giveaways to precise, data-driven coupon issuance. By analyzing historical transaction data and identifying predictive behavioral patterns, businesses can significantly enhance redemption rates and boost net profits—by nearly 50%, according to recent research.
The Challenge of Random Coupon Distribution
Traditionally, many merchants issue coupons broadly, hoping to attract attention and stimulate demand. But this scattergun approach often backfires:
- Non-targeted customers may perceive coupons as spam.
- Over-issuance increases promotional costs without proportional returns.
- Frequent discounts can erode brand value and train customers to wait for deals before purchasing.
For O2O platforms handling millions of transactions daily, the stakes are high. The solution lies not in reducing promotions, but in making them smarter.

Machine Learning: The Engine Behind Precision Marketing
The core idea of this study is simple yet transformative: predict whether a customer will redeem a coupon within 15 days of receiving it. If accurate, such predictions allow merchants to target only those users most likely to convert—maximizing impact while minimizing waste.
To achieve this, researchers leveraged machine learning techniques on a comprehensive dataset from Tianchi, Alibaba’s data science competition platform. The dataset includes six months (January–June 2016) of anonymized user behavior from an O2O service provider, capturing both online and offline interactions.
Why XGBoost?
Among various machine learning models tested, XGBoost (eXtreme Gradient Boosting) emerged as the optimal choice due to its:
- High performance on structured/tabular data
- Resistance to overfitting through regularization
- Built-in cross-validation and feature importance scoring
- Efficiency in handling sparse datasets
After rigorous tuning, the final model used 3,500 boosting rounds with optimized hyperparameters such as max_depth=5, subsample=0.7, and eta=0.01, achieving an AUC score of 0.7961—a strong indicator of prediction accuracy in binary classification tasks.
Feature Engineering: Turning Data Into Insights
Effective prediction relies not just on the model, but on meaningful input features. The study extracted 44 features across five key categories:
- Coupon Features: Denomination, discount rate, usage threshold
- Merchant Features: Number of coupons issued, merchant size, location density
- User Features: Past redemption behavior, frequency of visits
- User-Merchant Interaction: Historical transaction volume, distance between user and store
- Contextual & Temporal Features: Time of receipt, day of week, seasonal trends
These features reflect real-world consumer psychology and operational realities—such as how price-sensitive users respond to deeper discounts or how proximity influences redemption likelihood.
Notably, the top 10 most influential features included:
- Merchant's total coupon issuance count
- Discount strength (e.g., "20% off" vs. "Buy 1 Get 1 Free")
- Usage restrictions (e.g., minimum spend requirements)
Nine out of the top 10 were directly controlled or influenced by the merchant—highlighting their pivotal role in shaping redemption outcomes.
Key Findings and Business Implications
The model’s success goes beyond technical metrics—it delivers actionable insights for merchants:
1. Targeted Distribution Boosts Profitability
When coupons are sent only to predicted high-redemption users, net profit margins increase by nearly 50% compared to random distribution. This isn’t just about saving money; it’s about reinvesting marketing budgets more effectively.
2. Merchant-Centric Levers Drive Results
While consumers make the final decision, merchants control the most impactful variables:
- Setting optimal discount levels
- Balancing thresholds to encourage spending without deterring use
- Strategically timing coupon releases based on customer lifecycle stages
3. New Merchants Can Leverage Proven Patterns
Even businesses without historical data can benefit. By adopting best practices derived from top-performing features—such as offering threshold-free coupons during launch phases—they can design effective initial campaigns.

Practical Recommendations for Merchants
Based on the findings, here are three strategic actions merchants should consider:
✅ Align Coupon Design With Marketing Goals
- To attract new users: Offer high-value, no-threshold coupons (e.g., "$10 off first order").
- To boost profitability: Use moderate discounts with smart thresholds that increase average order value (e.g., "Spend $50, Save $8").
✅ Use Predictive Models for Inventory & Operations Planning
Anticipating customer demand through redemption forecasts allows for better staffing, inventory management, and capacity planning—reducing waste and improving service quality.
✅ Iterate and Improve Over Time
Start with general rules based on industry benchmarks. As transaction data accumulates, refine models continuously to improve targeting precision.
Frequently Asked Questions (FAQ)
Q: What is O2O coupon redemption prediction?
A: It’s a machine learning application that forecasts whether a customer will use a digital coupon within a specific timeframe (e.g., 15 days), enabling targeted distribution.
Q: Why is XGBoost effective for this task?
A: XGBoost excels at processing structured data with mixed numerical and categorical features—exactly the type found in transaction logs—and provides clear feature importance rankings for business interpretation.
Q: Can small merchants benefit from this approach?
A: Yes. While large platforms have more data, even small businesses can adopt simplified versions using third-party tools or platform-integrated analytics to identify high-potential customers.
Q: How much data is needed to build a reliable model?
A: At minimum, several thousand transactions with clear labels (redeemed vs. not redeemed) are recommended. More data generally improves accuracy, especially when segmenting user groups.
Q: Does this method work outside food delivery or retail?
A: Absolutely. The framework applies to any O2O service—including fitness classes, beauty appointments, or car washes—where digital promotions drive offline visits.
Q: Are there privacy concerns with using consumer data?
A: As long as data is anonymized and used in compliance with regulations (like GDPR or CCPA), predictive modeling respects user privacy while delivering personalized experiences.
