The internet or the World Wide Web is filled with limitless contents and websites. Whenever a user search for a particular term or phrase, the search engine provides a whole list of numerous websites and pages related to that particular keyword but how does a search engine know about the different contents in various different websites? How does it list the websites according to your needs or search queries? Well, this is where a ‘Web Crawler’ comes into action.
What is a Web Crawler?
A web crawler, also known as crawling agent, spider bot, web crawling software, website spider or search engine bot, is a digital bot or tool, which visits the various websites through out the world wide web and index the pages for the search engines. It is the function of the web crawler to learn about almost every content and information that is present on the world wide web so that it can be easily accessed whenever required.
Each search engine has its own version of a web crawler. A search algorithm is applied on the data collected by the web crawler through which search engines are able to provide you with the relevant information you are looking for. Various sources estimates that only 40 – 70% of the publicly available internet is indexed by web crawlers and that’s over billions of pages, so it can be said without a proper crawling application it would be very difficult for search engines to provide you with useful information.
To simplify the concept of web crawlers, let us compare the world wide web with a library. A web crawler is like someone who goes through an entire library and catalogues the books present in an orderly manner so that when readers visits the library, they can easily find what they are looking for.
Some well known examples of web crawlers are – Googlebot, Bingbot, Slurp Bot, DuckDuckBot, Baiduspider, Yandex Bot, Sogou Spider, Exabot and Alexa Crawler.

It is likely that a web page, which is being cited by many different pages and getting a lot of web traffic, contains high quality, informative content. So it is important for search engines to have it indexed.
Revisiting Web pages: Web contents are generally updated, removed or moved to new locations so it is important for web crawlers to revisit pages to make sure the new contents are properly indexed.
