•PageRank measures the importance of web pages by solving an equation of more than 500
million variables and 2 billion terms. PageRank interprets a link
from Page A to Page B as a vote for Page B by Page A. PageRank then
assesses a page's importance by the number of votes it receives.
•PageRank also considers the importance of each page that
casts a vote. Important pages receive a higher PageRank and appear at the
top of the search results.
•Google analyzes the full content of a page and factors in
fonts, subdivisions and the precise location of each word.
•Google also analyzes the content of neighboring web pages to
ensure the results returned are the most relevant to a user's query.
