Chrome extension uses JSON-LD first, DOM second to read product pages across marketplaces

Developers building a Chrome extension for product page optimization encountered inconsistent data presentation across platforms like Amazon and Shopify. Their solution prioritizes parsing structured JSON-LD data embedded in pages before resorting to platform-specific DOM selectors. This approach provides resilience against layout changes and normalizes data extraction across different marketplaces. However, they still use targeted DOM scraping to capture richer, real-time data not present in the structured blocks. The extension tailors its output to each marketplace's specific formatting requirements and language settings.
