Page Rank(PR) Algorithm

PageRank is a registered trademark and patented by Google on January 9, 1999 which protects a family of algorithms used to assign a numerical relevance of the documents (or web pages) indexed by a search engine. Its properties are discussed by experts in search engine optimization. The PageRank system is used by the popular Google search engine to help you determine the importance or relevance of a page. It was developed by the founders of Google, Larry Page and Sergey Brin at Stanford University.

The initial PageRank algorithm where their creators presented the prototype of Google: "The Anatomy of a Large-Scale Hypertextual Web Search Engine":

PR (A) = (1 - d) + d (PR (T1) / C (T1) + ... + PR (Tn) / C (Tn)

Where PR (A) is the PageRank of a page; PR (Ti) is the PageRank of pages that link to you A, C (Ti) is the number of outbound links on the page you; d is a variable factor which can be between 0 and 1.

PageRank relies on the democratic nature of the web by using its vast link structure as an indicator of the value of a specific page. Google interprets a link in a page A to page B as a vote, by page A, for page B. But Google looks beyond the volume of votes, or links a page receives and also analyzes the page that casts the vote. Votes cast by pages considered "important" worth more, and help to make other pages "important". The PageRank of a page is defined recursively and depends on the number and PageRank of all pages that link.

Benefits of Online Marketing Public Relations

Aside from possible media exposure, online press releases are an extraordinarily easy way to increase your website’s reach and rank within search engines.

The reach of your website is dramatically increased as your promotional press release makes its way all over the web through news distribution sites. This larger reach opens up numerous channels for traffic to get to your site.

In addition to increasing the reach of your site, online press releases also increase your site’s rank. Search Engines rely on more than keyword frequency within a site to determine if the site should be displayed or not. They also rely on the number of sites linking to your site. The thinking is that the more sites that link to yours, the more likely your site stands as credible and expert.

Whenever you submit any press release.Within minutes the release is featured all over the web from new-related sites to industry blogs. Overnight your site will be seen by search engines as being linked to by not one or two sites, but hundreds. This increase in the number of sites linking to your own will both increase the number of channels for traffic to make it to your site, but also increase your site’s rank, achieving a higher position in related search engine queries.
