What is WEB CRAWLER? What does WEB CRAWLER mean? WEB CRAWLER meaning - WEB CRAWLER definition - WEB CRAWLER explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. A Web crawler is an Internet bot which systematically browses the World Wide Web, typically for the purpose of Web indexing. Web search engines and some other sites use Web crawling or spidering software to update their web content or indexes of others sites' web content. Web crawlers can copy all the pages they visit for later processing by a search engine which indexes the downloaded pages so the users can search much more efficiently. Crawlers consume resources on the systems they visit and often visit sites without tacit approval. Issues of schedule, load, and "politeness" come into play when large collections of pages are accessed. Mechanisms exist for public sites not wishing to be crawled to make this known to the crawling agent. As the number of pages on the internet is extremely large, even the largest crawlers fall short of making a complete index. Crawlers can validate hyperlinks and HTML code. They can also be used for web scraping (see also data-driven programming).

The process that search engines use to search through websites and index them is called spidering. The search engines use automated programs, also known as spiders, to crawl through the Internet and collect data. The spiders will follow links that they come across before moving on. The more links to your site, the more likely it is that spiders are to crawl to your site and index it in the search engine. Another way to get search engine optimization advantage is to consistently check how your SEO is going. After all, what good is SEO if you cant tell if its working? In todays hectic world, you cant afford to waste time or money on search engine optimization thats not going to get results.
