Deep Crawling refers to a technical method in which a web crawler not only collects information from the homepage or surface pages of a target website but also recursively follows links within pages to continuously access and collect data from deeper levels of the site. Unlike shallow crawling, which only captures surface-level pages, deep crawling can penetrate a website's directory structure, pagination navigation, category links, and dynamically loaded content, thereby obtaining more comprehensive and complete data resources. This technique typically requires the integration of link deduplication, crawling strategy optimization, anti-scraping mechanism handling, and distributed scheduling to efficiently and stably complete large-scale data collection tasks.

Data deduplication is a data optimization technology that identifies and eliminates duplicate copies of data in a data set, retaining only a unique copy of the data and its reference, thereby reducing storage space usage, reducing data transmission volume and improving data management efficiency.
