PageRank rely on judge

Social search The concept of social ranking can be considered to derive from Google's PageRank algorithm, which assigns importance to web pages based on analysis of the link structure of the web, because PageRank is relying on the collective judgment of webmasters linking to other content on the web.

depend on :
number and metric.

PageRank depend on number

PageRank The PageRank of a page is defined recursively and depends on the number and PageRank metric of all pages that link to it ("incoming links").

Google economy The PageRank of any single web page depends on the number of web pages that link to it, the PageRank of the linking sites, and whether those links appear to be natural or manipulative.

PageRank depend on metric

PageRank The PageRank of a page is defined recursively and depends on the number and PageRank metric of all pages that link to it ("incoming links").

measured :
impact and cost.

PageRank measured impact

PageRank The PageRank may also be used as a methodology to measure the apparent impact of a community like the Blogosphere on the overall Web itself.

PageRank measured cost
