Price tracking is the process of monitoring the prices of goods and services over time to observe fluctuations and identify favorable buying opportunities. It is used by consumers, retailers, and researchers to analyze pricing dynamics, detect discounts, and forecast cost trends.

Core features include price histories, price-change alerts, and comparisons across retailers. Data is collected from retailers, marketplaces, and coupon sites through methods such as web scraping, application programming interfaces, and manual input. Collected data is organized by product identifiers (for example, SKUs, model numbers, or ASINs) and geographic region, since prices vary by location and currency.

Typical use cases include consumers setting alerts for price drops, planning purchases around historically low prices, or comparing offers. Businesses perform competitive benchmarking and inventory planning. Researchers study price elasticity and market efficiency.

Limitations and challenges include data quality, incomplete coverage, and inconsistent product identifiers. Price data can be noisy due to promotions, stock status, shipping and taxes, or seller-specific deals. Legal and ethical issues surround web scraping, terms of service, and rate limits. Technical challenges include dealing with dynamic websites, anti-scraping measures, and currency conversions.

History of price tracking began with early price comparison sites and manual diary tracking, evolving to automated trackers and browser extensions in the 2000s and 2010s. More recently, there is increasing use of AI-assisted analytics and APIs for programmatic access, enabling more scalable and granular price analyses.
