Web scraping vs web crawling isn’t *that* hard once you get it. Crawlers are for discovery, scrapers are for extraction.
For example, if you wanna monitor prices on Amazon, you don’t need a crawler—just scrape the product pages directly. But if you’re building a directory of all blogs in a niche, you’d crawl first to find them.
Tools? For scraping: BeautifulSoup + Requests. For crawling: Scrapy or even Heritrix if you’re hardcore.
