Scraping e-commerce websites and product pages is a common practice driven by several key reasons, such as:
Market research: Uncover trends and insights to inform business strategies
Price monitoring: Track competitors' pricing and stay competitive
Product catalog enhancement: Enrich product information and improve customer experience
Lead generation: Identify potential customers and drive sales
Content aggregation: Collect and analyze data to support business decisions
E-commerce websites are typically challenging to extract data from because they involve complex HTML element structures and may undergo frequent updates, which can change the layout and invariably impact CSS selectors. This means that, for example, a CSS selector used to extract a product price may be changed in future website updates, thereby affecting the consistency of your scraping process.
Furthermore, dynamic e-commerce websites may have different structures for different products or product categories. Making extracting key information rather difficult as CSS element vary across product items.
How it works
The JigsawStack's AI Scraper takes a novel approach to tackle situations like this. By leveraging intuitive prompts, it effortlessly extracts data from any website, eliminating the need for complex selectors or scripts. Unlike traditional methods that require knowledge of specific selectors (e.g: .product-category.product-price), JigsawStack's AI Scraper uses natural language prompts (e.g., "product price") to retrieve the desired data. This approach ensures that even when selectors are updated or changed, the AI Scraper continues to retrieve the same accurate data.
