It is worth noting from the very beginning that PageRank (or PR) is often a ranking employed by Google to ‘grade’ webpages. This grading is just not depending on a variety of factors and it is meant to give a value on the website that ranges from to 10.
Also it is very important note that whilst the PR only applies to particular page – which means that while a site could have a high Pagerank on its main page, some of the other internal pages might have lower PR scores.
Depending on this understanding, it should be easy enough to appreciate that ‘high PR backlinks’ have to result from a webpage which has a real high PR score, as opposed to simply any web site where the main page features a high PR score nevertheless the inner page where the backlink is situated will not.
Also it must be apparent that backlinks from pages with higher PR count ‘more’ than pages with lower PR.
The actual algorithm that is used to calculate the precise ‘value’ of high PR backlinks isn’t known – but tests have demostrated time and again a single backlink from the webpage having a PR of 7 roughly seems to provide more value than over 10 backlinks from webpages with PR1 or PR2.
Fact in the matter is, the real importance of quality backlinks is most beneficial measured when it comes to simply how much they are able to increase your ranking on search engine listings – because that is what you are interested in acquiring them for, right?
Since Google (and also other search engines like yahoo) are focused primarily on offering the most accurate and reliable search results as is possible, using backlinks to influence 94devppky results is one of their methods of boosting the reliability of those results.
And considering the fact that in general high PR websites are fairly reliable and won’t just farm out links like another websites do – search engines like google have a tendency to take that into account.
It isn’t an excessive amount of a stretch to figure that although the price of mass backlinks from low PR webpages might decrease after a while, value of having a handful of backlinks from high PR webpages will not be gonna. Granted, it can be impossible to calculate what search engine listings will think about in their algorithms later on, but it is a secure bet that the logic behind why high PR backlinks count for ‘more’ will remain the same.
Keep in mind that although ‘PageRank’ is really a grading system used only by Google – other search engines like google have been recognized to employ similar grading systems and very often pages rich in PageRank find yourself doing well on these other systems too.
