Case Study: Automated Price Aggregation for Competitive Intelligence in E-Commerce

Challenge

In the fast-paced world of e-commerce, pricing is one of the most influential factors that drive consumer choice. For major retail businesses, staying competitive requires real-time awareness of market prices across thousands of SKUs. Our client, a leading player in the e-commerce retail sector, was relying on manual tracking and fragmented tools to monitor competitors’ pricing, which was inefficient, slow, and error-prone.

Given the scale of operations and the volume of products they managed, it became increasingly difficult to make informed pricing decisions quickly. There was a clear need for a robust, automated solution that could consistently track competitor pricing and empower data-driven decisions.

Goals

  • To develop an automated solution for monitoring competitor prices across multiple e-commerce websites.

  • To improve pricing strategies and stay competitive in real-time without manual intervention.

  • To enable better decision-making by aggregating product-level pricing insights across SKUs and platforms.

  • To enhance customer acquisition and retention through competitive pricing models.

Requirements

  • A scalable web crawling infrastructure capable of handling thousands of pages per crawl cycle from multiple domains.

  • Intelligent mapping of client SKUs with competitor product listings, even if naming conventions varied.

  • Data normalization and enrichment pipelines to clean, structure, and standardize extracted information.

  • A dashboard or exportable format to view and act upon pricing deltas across categories.

  • Alert mechanisms for major price drops or changes in best-selling competitor products.

  • Ability to schedule automated crawls at regular intervals for near real-time insights.

Solution

We built a custom price aggregation system tailored to the client’s operational and strategic needs:

  • Automated Web Crawlers: Developed using .NET and headless browser automation frameworks to extract product prices, SKUs, and metadata from a large set of e-commerce competitors.

  • Intelligent Matching Engine: Integrated fuzzy matching and rule-based logic to accurately pair client SKUs with similar competitor listings, overcoming inconsistencies in product naming.

  • Centralized Data Processing: Built a backend pipeline to clean, deduplicate, and normalize data before pushing it to the client’s business intelligence system.

  • Custom Dashboards and Exports: Delivered data in both real-time dashboards (via internal tools) and structured exports for integration into the client’s pricing systems.

  • Monitoring and Failover Systems: Added logging, retry, and fallback systems to ensure reliability across changing website structures and anti-bot mechanisms.

Technologies Used

  • Backend: ASP.NET, C# (.NET Core)

  • Data Crawling & Processing: Console Application with multithreading for high-performance crawling and task parallelism

  • Database: SQL Server for structured data storage and query optimization

  • Automation & Scheduling: Windows Task Scheduler and internal job orchestration logic for scheduled runs

  • Data Matching Engine: Custom logic using string similarity and rule-based mapping for SKU-product correlation

  • Integration & Output: Export modules generating reports in Excel/CSV for internal consumption and decision-making

Result

  • Real-time Competitive Insights: The client now receives structured pricing data across competitors with minimal latency, enabling faster and smarter decision-making.

  • Improved Pricing Strategy: Allowed the business to undercut competitors tactically, resulting in increased conversion rates and reduced customer churn.

  • Scalability Achieved: The system scaled from a few hundred SKUs to tens of thousands with negligible additional overhead.

  • Profit and Customer Growth: Since implementation in 2012, the client has seen a manifold increase in profit margins, enhanced customer retention, and a consistent rise in new user acquisition.

  • Zero Manual Dependency: What used to take days now happens in hours or minutes, allowing the client’s team to focus on strategy instead of data collection.
