Do you know about Web crawler? If your answer is yes or it is no then in both the cases you will be surely benefited by exploring the actual meaning and history of Web crawler.

In general definition, a Web crawler is nothing other than a search engine or better to say a meta-search engine, which intermingle the search results from the top notch search engines like Google, Bing, Ask.com, Yahoo, About.com, and others. The most common or better to say the famous examples of web crawlers are search engines.

It is also known by different names like web spider, web bot or site scrappers and is a web service, which helps in the users of the web to navigate by automating the task of link traversal, and making a searchable web index etc.

Web crawler gives the users the ability to search and find photos, news highlights, songs, videos, and much other functionality. In conceptual terms, web crawler is simple. It builds an index of the web and takes queries from the searchers through the Web, thereby returning the most relevant documents as results to the user. It acts as a node in the Web graph which consists of the links to different Websites on the Internet, thereby constraining the pathway between the user and its target.

Let us go back to the history of the Web crawler in short. It was the first introduced and the used Web search engine that was providing full text search. The date of release of Web crawler was April 20, 1994.

In terms of its functionality, the Web crawler is basically a search engine that carries its own record of data and which also displays the advertising results in the separate areas of the Web page. The Web Crawler has been relocated as a meta-search engine that is designed specifically to provide the sponsored and non-sponsored search results from most of the popular search engines.

Finally, what crawling does in the last is that is make up a collection of Web pages at an essential location. As with the nonstop extension of the Web, the crawled collection is assumed to be the subset of the Web, which may be far smaller that the overall size of the Web.
