Importance of Page Rank (PR)

PageRank resembles the importance of a page on web. Google figures that when one page links to another page, it is effectively casting a vote for the other page. The more votes that are cast for a page, the more important the page must be. Also, the importance of the page that is casting the vote determines how important the vote itself is. Google calculates a page's importance from the votes casted for it. How important each vote is, is taken into account when a page's PageRank is calculated. PageRank is Google's way of deciding a page's importance. It matters because it is one of the factors that determines a page's ranking in the search results. It isn't the only factor that Google uses to rank pages, but it is an important one.

Note: Avoid link farms and try to get industry specific links for your site for better performance of site on web.

What is meant by SEO ?

Search engine optimization (SEO) is the process of improving the volume and quality of traffic to a web site from search engines via "natural" ("organic" or "algorithmic") search results for targeted keywords. Usually, the earlier a site is presented in the search results or the higher it "ranks", the more searchers will visit that site. SEO can also target different kinds of search, including image search, local search, and industry-specific vertical search engines.

It is the art and science of increasing your website’s visibility to search engines for those important keywords and phrases that are relevant to your business.

It consists of off page and on page activities. Both contribute equally in promoting a site.
