The eyes

[hassen1]

The eyes of the search engine are the spiders (AKA robots or crawlers). These are the 1s and 0s that the search engines send out over the Internet to retrieve documents. In the case of all the major search engines the spiders crawl from one page to another following the links, as you would look down various paths along your way. Fortunately for the spiders they are traveling mainly over fiber optic connections and so their ability to travel at light speed enables them to visit all the paths they come across whereas we as mere humans have to be a bit more selective.

What is this about eyes ?The term "search engine" is often used generically to describe both crawler-based search engines and human-powered directories. These two types of search engines gather their listings in radically different ways. Crawler-based search engines, such as Google, create their listings automatically. They "crawl" or "spider" the web, then people search through what they have found.If you change your web pages, crawler-based search engines eventually find these changes, and that can affect how you are listed. Page titles, body copy and other elements all play a role.
