Hello friends,

How does Search Engine index a Website..?

Search Engine index a website is by "spiders" of google.
First Spider retrieve a list of servers and popular sites. Spider will start searching for a particular site, it indexes from its site and follow the links (links) found within this Site. Under this method, the search engine Google will do the job quickly and spread out all the sections of the most widely used web.
When Spider review sites (in HTML format), it noted: The words within the site & find where it's from. The word appears in the Title tag, Meta Description .... it says it is an important part related to the user's search later.
