Chaining

Chaining links multiple extractors together, using the output of one as the input for another. This enables multi step data collection processes such as going from category pages to product detail pages.

Why it matters

• Increases the depth and completeness of data
• Supports extraction across complex site structures
• Reduces manual URL preparation and improves coverage

How it is used

• Listings to product detail workflows
• Multi page crawling for large categories
• Layered extraction to enrich datasets
