Web Robots: Web Crawlers
Web robots, also called web crawlers or spiders, are programs that systematically browse the web to index web pages for search engines. They crawl websites to gather information and store it in a searchable database.
What is Web Robots?
Web robots, also called web crawlers or spiders, are automated programs that browse the World Wide Web in a methodical, automated manner. Their main purpose is to index websites and their pages to make them searchable on search engines like Google, Bing, and Yahoo.
When a web crawler visits a website, it will follow all the hyperlinks on each page to crawl the entire site. As it browses, the robot extracts information about the pages such as titles, content, metadata, file types, etc. and stores this information in a search engine's database. This allows users to search for content on websites via search engines.
Some key abilities and functions of web crawlers include:
- Automatically crawling from website to website by following hyperlinks
- Scanning web page content and metadata
- Extracting keywords, titles, descriptions, media, and other metadata
- Storing the extracted information in a searchable web index
- Handling large volumes of web pages across many websites
- Revisiting websites periodically to check for updates
- Following sitemap protocols for efficient site crawling
Major search engines like Google, Bing, Yandex, and Baidu all utilize sophisticated web crawlers to index billions of web pages. This allows for fast, relevant search results. Besides search engines, other applications of web robots include feed aggregators, plagiarism checkers, market research, web monitoring, and more.
