Page Rank is Still Useful in SEM

By Sky Alfaro

There have been many articles written on the subject of page rank by SEOs who will tell you that Page rank is worthless, and that it has no bearing on the rank of a page within Googles search results.

Whatever anyone tells you, Page Rank is a measure of quality (as Google sees it), all be it an inaccurate one. For example, how many PR6 spam sites have you seen? Ill wager not many, perhaps none at all. Conversely, there are millions of spam PR0 " PR2 sites.

The next time an SEM Company tells you page rank is worthless ask them whether they would exchange a PR6 link for a PR0 link? The answer should be know, as a PR6 site will almost always be more important than a PR0 site.

In case you do not already know, Page Rank is a metric Google assigns to a site to indicate / measure its perceived importance.

Page rank is assigned on the basis of links pointing to a given website. As pages link to each other, the rank of one page passes to the other. This gos for both internal and external links.

Page rank is a represented as a number between 0 and 10. The higher the number the more importance Google places on that page. Pages that show NA in their page rank are usually new sites that Google has not properly analysed, or sites that Google has banned.

As page rank is passed from site to site, the higher the PR value of pages linking to a give site, the higher the assigned value of the target site will be.

Although there is no supporting evidence, some SEOs insist that the content of a site, or the frequency of update also has a bearing on Page Rank, however, if this were the case it is likely that someone would have proved it through experimentation by now, which, at time of writing has not happened.

The structure of the site has a major role to play in the distribution of PageRank. Google uses what is known as block level analysis to pick apart web pages. They use their knowledge of the architecture of the internet to decide what links on a page are probably the most important and the pages these links point to are more likely to receive PageRank.

Lastly, the assigned page rank of a given site may fluctuate even when there has been no obvious change to the site, or the sites linking to it. This will be due to changes to the link profile of other sites in the chain (those linking to those linking to you) or alterations in the Google Algorithm
