API-Powered Smart Product Selection System: How to Automatically Identify Potential Bestsellers

As competition intensifies in both cross-border and domestic e-commerce markets, product selection has become a critical component of the entire e-commerce operations chain. Traditional methods that rely on manual research and experience are no longer sufficient to handle the fast-changing, data-heavy landscape.

Today, by integrating third-party data APIs into product selection systems, we can build an intelligent engine to automatically identify potential bestsellers, significantly improving selection accuracy and responsiveness.

1. Key Metrics for Identifying Potential Bestsellers

To effectively identify potential bestsellers, we must first define their key characteristics. Based on platforms like Walmart and Amazon, the following indicators are essential:

  • Rapidly increasing number of reviews indicates growing sales momentum.

  • High ratings (above 4.5) and high-quality review content suggest customer satisfaction.

  • High keyword ranking reflects strong visibility in search results.

  • Recently launched or newly listed products are often “dark horse” contenders.

  • Competitive pricing within category range increases attractiveness and conversion rates.

These factors form the foundation for any automated product identification model.

2. Key API Support from LuckData

LuckData provides data APIs for Walmart and Amazon that extract all the key metrics mentioned above. These APIs enable your selection system to access real-time, structured product information:

3. Workflow to Build a “Potential Bestseller Identification Model”

An automated identification system typically includes the following five steps:

1️⃣ Keyword Pool Construction

Start by building a keyword pool based on popular terms within your target categories. For example, in consumer electronics, use keywords like "gaming laptop" or "wireless earbuds." Use the search API to pull related product lists, expanding your sample base.

2️⃣ Product Data Collection

Use the product details API and review API to retrieve essential metrics such as rating, number of reviews, listing date, price, and stock status.

3️⃣ Data Cleaning and Structuring

Convert raw API results into structured tables and calculate the following derived indicators:

  • Review growth rate (past 7 days vs. total)

  • Estimated daily sales (inferred from review increments and market ratios)

  • Category ranking trends (if historical snapshots are available)

  • Product lifecycle stage (new or mature listing)

This standardized dataset becomes the input for further analysis.

4️⃣ Rule-Based Filtering Model

Set logical rules and thresholds to flag potential bestsellers. Sample criteria may include:

  • Listed within the past 30 days

  • Rating ≥ 4.5

  • Review growth rate ≥ 30%

  • Price within ±20% of category average

Products meeting these multidimensional criteria are tagged as “potential bestsellers” and prioritized for monitoring.

5️⃣ Output and Display

Display the filtered product list on a frontend interface, with support for actions like CSV export, tracking, monitoring list inclusion, and daily updates for decision-making.

4. Automated Selection vs. Manual Selection: A Comparison

Dimension

Manual Selection

Automated (API + System)
