a system for ranking web pages developed by their founders Larry Page and Sergey
Brin at Stanford University. While they have dozens of engineers working to improve
every aspect of Google on a daily basis, PageRank continues to provide the basis
for all of their web search tools.
PageRank relies on the uniquely democratic
nature of the web by using its vast link structure as an indicator of an individual
page's value. In essence, Google interprets a link from page A to page B as a
vote, by page A, for page B. But, Google looks at more than the sheer volume of
votes, or links a page receives; it also analyzes the page that casts the vote.
Votes cast by pages that are themselves "important" weigh more heavily
and help to make other pages "important."
sites receive a higher PageRank, which Google remembers each time it conducts
a search. Of course, important pages mean nothing to you if they don't match your
query. So, Google combines PageRank with sophisticated text-matching techniques
to find pages that are both important and relevant to your search. Google goes
far beyond the number of times a term appears on a page and examines all aspects
of the page's content (and the content of the pages linking to it) to determine
if it's a good match for your query.

is an important factor in how and where your website ranks in search engine results.
Pagerank plays one of many important factors in your sites visibility in search
engine listings. It has been suggested that there could be hundreds if not thousands
of different criteria's responsible for the actual results from the technology
behind search engine algorithms.
