How does a rapid URL indexer differ from a standard web crawler?

While both crawl websites, a rapid URL indexer is optimized for speed and efficiency, specifically for large-scale URL processing. Standard web crawlers might be slower and less configurable for rapid indexing. Rapid indexers often incorporate techniques like parallel processing and optimized data structures to achieve higher throughput. They are also usually designed with features tailored for submitting content to search engines, such as optimized URL submission methods and reporting.
