Learning Unit Summary

Google uses PageRank™ to examine the entire link structure of the web and determine which pages are most important.
Instead of counting direct links, 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 is a numeric value (from 0 to 10) that represents how important a page is on the web and is Google's way of deciding a page's importance.

There is no human involvement or manipulation of results, which is why users have come to trust Google as a source of objective information untainted by paid placement.

Google's search engine also analyzes page content. However, instead of simply scanning for page-based text (which can be manipulated by site publishers through meta-tags), Google's technology analyzes the full content of a page and factors in fonts, subdivisions and the precise location of each word.

Inbound links (links into the site from the outside), are one way to increase a site's total PageRank.
