Data Mining vs Web Scraping
Scraping acquires data, mining analyses it. How the two fit together in a pipeline, and why the distinction decides what you instrument and where proxies sit.

Parsing HTML and JSON Reliably
Writing selectors that survive redesigns, validating output with a schema, and defensive parsing so one missing field does not corrupt a whole dataset.

Handling Pagination in Scrapers
Offset, cursor and infinite-scroll pagination, detecting the end condition, deduplicating across pages, and resuming a crawl after a failure.

Web Scraping vs APIs
When an official API is available and sufficient, use it. How the two compare on reliability, cost, limits and legal footing, plus the hybrid approach.
