What is a Web Crawler?
When it comes to efficiently extracting data from websites, a web crawler plays a huge role. Also known as a web spider or web robot, a web crawler is a specialized tool designed to browse the internet methodically and automatically.
Here’s how it works:
- Web crawlers start by fetching a few web pages and then follow the links on those pages to solve out new URLs.
- They use algorithms to determine which sites to crawl, how often, and how many pages to fetch.
- One of the key advantages of using a web crawler is its ability to find the way in the large web world at a much faster pace than manual extraction methods.
- By automating the process of data extraction, web crawlers save us useful time and ensure the accuracy of the extracted information.
Web crawlers are the backbone of search engines like Google, Bing, and Yahoo, as they continuously scan and index web pages to provide relevant search results to users.
