PageRank
PageRank
is
the
concept
that
enabled
Google
to
leap
frog
over
other
search
engines
during
the
late
1990s
in
terms
of
relevant
search
engine
results
pages
and
speed
of

PageRank
holds
US
patent
number
6,285,999

4th
September

Larry

one
of
Google’s
founders.

on
established
practice
for
scientific
papers
where
the
importance
of
a
paper
is
based
on
the
number
of
citations
made
to
it
by
other
papers.
The
Google
algorithm
interprets
a
link
from
one
page
to
another
as
a

The
Google
algorithm
and
the
configuration
of
web
pages
means
that
PageRank
can
be
fed
back
so
that
pages
that
have
more
votes
are
then
deemed
to
be
more
important
and
the
votes
they
cast
(outbound
links)
are
subsequently
given
more
weight.
