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 history
With 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 search
ii – 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 history
With 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 search
ii – 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.
2007-05-10 20:00 $464.82

Large-Scale Hypertextual Web Search Engine.
•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 W ebmaster'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 ). W ikipedia, 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.
Have you seen MyMaps?
