- FetchCategory pagination required session-stable headers.
- ParseMixed card layouts — fallback selectors per template.
- StructureDeduped by extension ID across overlapping categories.
The problem
A research team needed structured metadata — ratings, reviews, developer signals, and pricing — across the Chrome Web Store without manual copy-paste or brittle one-off scripts.
Approach
- 01Mapped category URLs and pagination patterns across 18 store segments.
- 02Built resilient fetch logic with rate limiting and session rotation.
- 03Normalized records into a consistent JSON schema with deduplication by extension ID.
- 04Delivered preview samples in the Lab and full export on request.
Deliverables
- ▸Structured JSON dataset with extension metadata
- ▸Screenshot-backed previews in the Lab
- ▸Repeatable scrape pipeline for refresh cycles
