Breadth-First Search (BFS) explores graph nodes level-by-level. In crawling, BFS grabs all links from a page, then all links from those pages, expanding outward evenly. This yields broad site coverage before diving deep.
Why use BFS with Proxied?
High discovery rate: Quickly maps an entire domain structure.
Proxy rotation synergy: Each new page fetch can roll to a fresh IP from our mobile pool, preventing pattern-based blocks during large-scale crawls.
