Spider: While browsing on net, you must have for at least once come across the option ‘view page source’. If you select this option you get to see the HTML (or otherwise any other, say, JAVA) source of the page. Spider is the software which in a way skips the normal path to the page source and shows you the page source directly.

Crawler: This program shows you the links present on a webpage and gives path to the crawler through the links on the webpage. Thus this program gives for the crawler to find the documents not falling under the eyes of the search engine except unless prohibited to do so. The alternate option is to let the crawler go on predefined addresses.

Indexer: The indexer helps you to split the details of a webpage for your convenience as to how many headers or footers are used on the page, what and at how many places any special characters are used. Included in this are the details of the HTML tags etc.

Database: Also known as the index of the search engine, here the data is stored by the search engine after downloading for its analysis.

Results Engine: This is the crucial component for the raking. It is the component which any search engine optimizer has to satisfy most to get his/her page ranked high. As per the data or algorithms with the search engine this component matches and decides which web page is most matching to the queries by a user and that page is ranked as first in the ranking.
