Client Overview
An early-stage e-commerce market-intelligence SaaS platform needed comprehensive Mercado Libre Argentina data to help sellers understand what sells, who sells it, and at what price. The solution was designed for expansion into Mexico and Brazil.
Scope: Product listings, prices, seller reputation, sales indicators, category rankings, and competitor catalogues.
Frequency: Daily collection for priority categories and weekly collection for the remaining categories.
Delivery: Parquet files and API.
Key Challenges
Broad coverage: Millions of listings across thousands of categories required scalable data collection.
Seller intelligence: Users needed competitor catalogues, pricing, reputation, and active listings.
Sales estimation: Cumulative and rounded sold indicators required careful estimation.
Inflation and currency: Argentina's changing prices required dated currency references and inflation-adjusted trends.
Product Data Scrape Solution
Product Data Scrape mapped Mercado Libre Argentina's category tree and selected 400 priority categories for daily collection, with other categories monitored weekly.
The pipeline captured listing IDs, product titles, current and original prices, discounts, condition, shipping, fulfilment, installment offers, sold indicators, ratings, and reviews. Public seller-level information included reputation, sales badges, active listings, and province.
Changes in sold indicators were used to estimate units sold per period. Rounded indicators were reported as ranges rather than exact figures. Prices were stored in Argentine pesos, with dated USD reference values and inflation-adjusted historical comparisons.
Sample Data Fields
The structured dataset included site, listing ID, category, product title, price in ARS, original price, USD reference price, condition, free shipping, fulfilment type, installment offers, sold indicator, estimated seven-day sales, seller name, reputation, seller badge, province, rating, reviews, and collection timestamp.
Illustrative Category Insights
| Category | Active sellers | Top 10 sellers' share of estimated units |
|---|---|---|
| Smartphones | 2,140 | 46% |
| Running Shoes | 1,380 | 31% |
| Kitchen Appliances | 3,050 | 27% |
| Kids' Footwear | 960 | 38% |
Inflation-adjusted median price changes over 30 days ranged from -2.1% for smartphones to +1.4% for kids' footwear in the illustrative dataset.
Results
1.8 million listings collected daily
210,000 sellers profiled
400 categories with daily seller rankings
7 weeks to launch the first dashboard
The platform launched a Category Explorer for demand and competition, a Seller Tracker for competitor catalogue and price changes, and a Price Position tool for category-level pricing comparisons. Additional modules supported opportunity discovery and fulfilment analysis. The pipeline was subsequently extended to Mexico and Brazil.
Key Lessons
Seller-level intelligence provides value beyond product prices alone.
Estimated sales should use ranges when source indicators are rounded.
Inflation adjustment is essential for meaningful price comparisons in Argentina.
Prioritizing 400 categories for daily collection helps manage coverage and costs.
Unlike one-time market-entry research, a seller-intelligence SaaS requires continuous data collection, historical records, and seller-level tracking.
