This video systematically analyzes the core differences and practical application scenarios of Web Crawling and Web Scraping. Web crawling is akin to an automated web browser that systematically traverses the entire website structure by following links, primarily used for scenarios like search engine indexing, SEO audits, and contentaggregation. Web scraping, on the other hand, focuses on precisely extracting desired data from specific pages, widely applied in areas such as price monitoring, brand management, and AI model training. The video clearly demonstrates the applicable scenarios of these two technologies through real-world examples like Google searching the White House, news aggregators, and competitor price monitoring. For scenarios requiring bulk data collection from multiple pages, it is often necessary to combine crawling logic with scraping techniques. The content also introduces how to simplify the data acquisition process through Scraping API tools, enabling scheduled crawling and automated data updates, which is highly suitable for professional users who need data collection, market monitoring, or multi-account management.
