Improved page engine rank is a term used by those with confusion with SEO and page optimization and Google Page Rank - properly Page Rank by the way. It is a trade marked term registered by Google, although the patent for the Page Rank system of calculating and assigning it is assigned to Stanford University where Page developed the system, not Google.

What most people do not know is that the term Page Rank originates from the name of one of the developers, Larry Page. Hence Page Rank. He later teamed up with Sergey Brin to form Google in 1998.

Enough of history: that is in the past! The present is that Google Page Rank that I will henceforth refer to as Page Rank for fear of breaking copyright law, has been publicly stated by Google as being one of the predominant means of determining the listing of a website for a particular search term.

This might not last for a lot longer, since there are whispers that Google are considering reducing the importance of Page Rank in view of the increasing relevance of social bookmarking and other social sites such as Del.icio.us and Digg.

Now there is Twitter run by Google and more and more Twitter results are turning up in Google search results. Twitter is what is called a micro-blogging service that uses SMS and instant messaging, or the blog posts on the Twitter website. Face book is also being used by more and more people, but a lot are college students and others trying to spy on and stalk ex lovers for what can only be assumed to be pretty nefarious reasons.

However, these uses of so called social networking sites are immaterial. It their existence that matters, and the association many of them have with major search engines that are producing so many search results somewhat less than useful when they should properly have been filtered out. The question is: Should Google and Yahoo be allowed to be associated with these sites and give them preference in search engine results by use of what can only be manipulation of the algorithms?

Perhaps Page Rank and Link Density will become less important than your registration and participation in these sites. That is why I have joined most of them. They are fun to participate in, but much of the content is very juvenile and amateurish and not what I would to find in a serious search. Blog postings are generally not useful content.

However, back to link density and Page Rank. It is highly unlikely that link density will ever be dropped by Google, but they might introduce some aspects of social bookmarking in to their algorithm. What this means is that if you want to improve your listing, you will have to be involved in Google related social sites, Twitter being the main one at the moment.

If you understand Twitter you will know what I mean when I state that Google might include, in addition to page rank and traditional SEO, the number of friends and comments, number of Twitter followers, photo uploads and frequency of updates. Keep an eye on Google activity and their acquisitions, since the more acquisitions of social sites Google make, and the more of their own they produce, then you can be pretty sure that at some time they will introduce elements of that into their algorithms.

So, get ahead of the race and get acquainted with Twitter. Google have made no changes yet, but the buzz is there, so don't bet your boots that no changes will be made in that direction sometime in the future. My belief is that article submission will remain the one major means of attracting traffic and obtaining one-way links back to your selected web pages for the foreseeable future, but those elements of social bookmarking and other social networking sites will gradually creep into the algorithms.

There is nothing to lose by being ahead in the game, and you have just been given a clue as to how to do that. It might be a year away, perhaps less and perhaps more, but when the day comes, if it does, I at least will be prepared for it.
