Crawlers are such essential tools on the Internet today that imagining a world without them would make navigating the web a different experience. Web crawlers assist in the operation of search engines, serve as the brains behind web archives, assist content creators in finding out what content is copyrighted, and assist website owners in identifying which pages on their sites require attention.
You can accomplish a lot with web crawlers that would be difficult or impossible without them. If you need to collect data from the Internet, you might need to use web crawlers at some point as a marketer. However, choosing a suitable web crawler for your needs may be difficult.
