I What About Google?

I.1 Google history

• Back in 1994, in Stanford, two friends, one finalists project ... and one Idea!

I.2 Google history

Consider an internet page. I know where it links to ... but ... I don’t know where it’s linked from.

Larry’s one-billion dollar pop quiz: Which pages link to this page?

I.3 Google history

A year later BackRub was born. Innovative, this program would send crawlers to slurp the pages in the integral and then it would index their links, thus providing for the first time a snapshot of the links structure of the internet.

A natural ranking of web pages followed. They called it the PageRank, from the name of its creator, Larry Page.

I.4 Google historyWith the index and the PageRank concept they pushed their data to the next level and created a novel search engine:i – It allowed full-text searchii – It ranked its results according to the PageRank principle

They named it Google, after a typo when trying to write googol (10100).

I.5 Google historyWith the index and the PageRank concept they pushed their data to the next level and created a novel search engine:i – It allowed full-text searchii – It ranked its results according to the PageRank principle

They named it Google, after a typo when trying to write googol (10100).Their moto is: “Don’t Be Evil!”

I.6 Google history

It released the GOOG stock on 2004 at $85 a piece.

•John Batelle, The Search.

I.7 S.E.O.

•Give data away (but make sure it gets packaged with a link coming back to your site)!! Provide a simple to use API. Ex: slideshare, youtube, del.icio.us, google!•Have lots of organic links coming back to you! Get people talking and posting about you. (www.digg.com)•Use Google Webmaster's tools (former sitemap) in order to facilitate Google's crawlers.•Use Amazon's Alexa or/AND Google Analytics to monitor and analyse your site traffic.•How many visitors COME BACK? How many are regulars? Are they daily, weekly, occasional visitors?•Use CSE and Google Co-op to create your adequate search engine.

I.8 Earth and Maps

•Conceptual revolution:•URL referenced documents will now get to be geo-referenced (a.k.a. Geo-tagging ). Wikipedia, panoramio, National Geographic, 3D structures etc...•Search business tries to refine geographically (google local) ...•But ultimately it strives to get to individuals web history and suggestions.
