Crawlers track links from page to page, while indexing all that they discover on their way. Since the number of pages on the Web is quite overwhelming, it is impractical for the crawler or spider to go to a website everyday to find out if there is a new page or if any modification has been done on an old page.

Subsequent to the crawling of a Webpage is its content indexing. An indexed page is kept in a big database until when it can be retrieved. Basically, the process involved in indexing is to identify the words and expressions that give the perfect description of the page and also the assigning of specific keywords to the page. At other times, right meaning of a page may not be dictated during the indexing process, but your optimization effort will assist the search engines in classifying your pages accurately, increasing your chances for higher rankings.
