Crawling or web crawling refers to an automated process through which search engines filtrate web pages for proper indexing. Web crawlers go through web pages, look for relevant keywords, hyperlinks and content, and bring information back to the web servers for indexing. As crawlers like Google Bots also go through other linked pages on websites, companies build sitemaps for better accessibility and navigation.
