Web crawlers, often referred to as spiders or search engine bots are automated software programs that download and index content from all over the web. The purpose of these bots is to identify the content of nearly every website in existence, enabling relevant information to be retrieved upon request. This process of acquiring data is known as crawling. Search engines use web crawlers to collect critical data to create search results. Whenever a user searches for something on a search engine, an algorithm based on the collected data produces a list of results corresponding to the query. Hence, web crawlers are essential to the functionality of any search engine. Applications of Web Crawler (Spider) Search engines such as Google, Bing, and Yahoo utilize web crawlers to gather data from web pages to construct their search engine catalogs. Web crawlers can analyze the text, links, and keywords in a webpage to measure its importance and relevance. Web crawlers can collect content from several websites and display them in one location, like news aggregation sites. These powerful software programs enable the formation of price comparison websites by gathering product prices across various e-commerce networks. This data can also be used for market research and security purposes, including scanning for vulnerabilities, detecting malicious code, recognizing potential security issues and helping website owners improve their search engine rankings. Moreover, web crawlers are also utilized for academic research applications, such as collecting information on social media utilization and online behavior.
