Google might use the following to determine the ranking of your pages:

- the frequency of web page changes
- the amount of web page changes
(substantial or shallow changes)
- the change in keyword density
- the number of new web pages
that link to a web page
- the changes in anchor texts
(the text that is used to link
to a web page)
- the number of links to low
trust web sites (for example
too many affiliate links on one
web page)

Your Google rankings can also
be influenced by your domain
name:

- the length of the domain registration
(one year vs. several years)
- the address of the web site
owner, the admin and the technical
contact
- the stability of data and host
company
- the number of pages on a web
site (web sites must have more
than one page)

How Google might rate the links
to your web site:

- the anchor text and the discovery
date of links are recorded
- the appearance and disappearance
of a link over time might be
monitored
- the growth rates of links as
well as the link growth of independent
peer documents might be monitored
- the changes in the anchor texts
over a given period of time might
be monitored
- the rate at which new links
to a web page appear and disappear
might be recorded
- the distribution rating for
the age of all links might be
recorded
- links with a long life span
might get a higher rating than
links with a short life span
- links from fresh pages might
be considered more important
- if a stale document continues
to get incoming links, it will
be considered fresh
- Google doesn’t expect that
new web sites have a large number
of links
- if a new web site gets many
new links, this will be tolerated
if some of the links are from
authorative sites
- Google indicates that it is
better if link growth remains
constant and slow
- Google indicates that anchor
texts should be varied as much
as possible
- Google indicates that burst
link growth may be a strong indicator
of search engine spam

Search results and user behavior
might influence your Google rankings:

- the volume of searches over
time is recorded and monitored
for
increases
- the information regarding
a web page’s rankings are recorded
and monitored for changes
- the click through rates are
monitored for changes in seasonality,
fast increases, or other spike
traffic
- the click through rates are
monitored for increase or decrease
trends
- the click through rates are
monitored to find out if stale
or fresh web pages are preferred
for a search query
- the click through rates for
web pages for a search term is
recorded
- the traffic to a web page is
recorded and monitored for changes
- the user behavior on web pages
is monitored and recorded for
changes
(for example the use of the back button etc.)
- the user behavior might also
be monitored through bookmarks,
cache, favorites, and temporary
files
- bookmarks and favorites are
monitored for both additions
and deletions
- the overall user behavior for
documents is monitored for trend
changes
- the time a user spends on a
web page might be used to indicate
the quality and freshness of
a web page

Miscellaneous factors that
can influence your Google rankings:

- web pages with frequent ranking
changes might be considered untrustworthy
- keywords that have little change
in the result pages are probably
matched to domains with stable
rankings
- keywords with many changes
in the results are probably matched
to domains with more votality
