Link Popularity PageRank is a link analysis algorithm that assigns a numerical weighting to each element of a hyperlinked set of documents with the purpose of "measuring" its relative importance within the set.
Link Diversity The relationship between the total number and variety of Linking Root Domains. Open Site Explorer includes 9.2 trillion links from 92 million domains. They have crawled 42 billion URLs in past 30 days.
Topical Relationships Links from trusted sites in the same topic or from relevant related sites.
Temporal Growth of Links Older links are often viewed as better than newer links. Link spikes can look unnatural to search engines. Majestic SEO has built an independent index of the internet to quantify link profile. Last crawl = 320 Billion Pages Crawled.

Other Link Based Ranking Factors Google has stated that Restricted TLD extensions (.edu, .mil, .gov, etc)do not pass any more value than others. Link schemes such as links to bad neighborhoods on the web or excessive link exchanging can negatively impact your site's rankings. Buying or selling links that pass PageRank is in violation of Google's Webmaster Guidelines. Paid links can negatively impact a site's ranking in search results. Nofollowwas developed by Google in 2005 as a method to identify a link that should not influence the link target's page rank. Originally developed for blog comment spam and later used to clearly identify paid links. Google & Bing look at social signals as a ranking factor, but that those signals are weak and may only apply to “Real Time” results for now.
