How do search engines work - Web Crawlers
Jul 1st, 2008 by admin
It is the search engines that finally bring your website to the notice of the prospective customers. Hence it is better to know how these search engines actually work and how they present information to the customer initiating a search.
There are basically two types of search engines. The first is by robots called crawlers or spiders.
Search Engines use spiders to index websites. When you submit your website pages to a search engine by completing their required submission page, the search engine spider will index your entire site. A ’spider’ is an automated program that is run by the search engine system. Spider visits a web site, read the content on the actual site, the site’s Meta tags and also follow the links that the site connects. The spider then returns all that information back to a central depository, where the data is indexed. It will visit each link you have on your website and index those sites as well. Some spiders will only index a certain number of pages on your site, so don’t create a site with 500 pages!
