Building a Price Scraping and Tracking Solution for Retail Market Insights

Two-Fold Price Tracking Complexity

1. Monitor Online Pricing: Scrape up-to-date product prices from competitor websites — even those designed to block bots.

2. Integrate Offline Prices: Ingest and reconcile physical store prices provided via APIs from multiple branches.

This required a flexible and scalable platform that could handle large datasets, normalize varying data formats, and present insights in a unified dashboard.

A Unified Approach to Real-Time Price Intelligence

We designed and implemented a robust PriceTracker system, focusing on four major components:

---

1. Web Scraping Pipeline

A dedicated scraper for each retailer was built with:

• Headless browser automation for dynamic HTML rendering

• Product mapping using SKU and fuzzy string matching

• Scheduled scraping to balance frequency and resource usage

---

2. Offline Price Data Integration

• Built an automated ingestion service to fetch store pricing via APIs

• Standardized the feed to align with scraped data formats

• Mapped and synchronized data from multiple retailers' branches

---

3. Data Cleaning & Normalization

• Removed promotional tags and non-essential data

• Standardized pricing to a uniform currency format

• Applied product categorization for consistent reporting

---

4. Centralized Storage & Dashboard

• Stored clean, structured data in a PostgreSQL database

• Built a user-friendly dashboard with filters and visualizations

• Provided pricing insights through charts, heatmaps, and trend indicators

The Result

Real-Time Price Visibility and Actionable Intelligence

The client gained an integrated platform that:

• Delivers daily competitive price insights
