ABOUT GOOGLE

Google

Google is an American multinational corporation specializing in Internet-related services and products. These include search, cloud computing, software, and online advertising technologiesFounded by :  Larry Page, Sergey Brin at 1996

HOW GOOGLE WORKS

1- Google sends out web crawlers(spiders - Googlebots), that go through all the web pages on the WWW.

2- these bots are made up of millions of computers that surf the Web like human , but all the time Googlebots are working on crawling and re-crawling websites .

how often a site is crawled depends on how quickly content

changes (newspaper site different from static one)

Crawling

3- the bots also detects all links on the site , which are then put into a queue system for crawling later on.

so finally we get this

4- Then taking the data on them back to

Google’s servers.

The web is like a book with millions of pages , and Google’s job is to index that book

HOW GOOGLE WORKS

Crawling

- Copies of all crawling pages are stored in Google’s index database.

- Google index is well over 100,000,000 gigabyte

- Google has spent 1 million computing hours building the index

Indexing

HOW GOOGLE WORKS

When user types in a query in the search engine ,

the index will match the query with all the webpages in which the query terms appear and then return the pages for the search results .

Web pages are ranked on terms of relevance before they are displayed on the result page .

GOOGLE TIMELINE

• Content on the web is blossoming. So we need more fresh and fast data.

Old index had several layers , updated every couple of weeks. To refresh we would analyze the entire web, which meant there was a significant delay between found a page and made it available.

With Caffeine, Google analyze the web in small portions and update our search index on a continuous basis
