It really is worth noting from the very beginning that PageRank (or PR) is often a ranking made use of by Google to ‘grade’ webpages. This grading is not according to various factors and it is meant to offer a value towards the website that ranges from to 10.
Also it is essential to note that even though the PR only applies to particular page – meaning that while a site could have a high Pagerank on its main page, several of the other internal pages may have lower PR scores.
Based on this understanding, it ought to be easy enough to appreciate that ‘high PR backlinks’ must are derived from a website containing an authentic high PR score, rather than simply any site where the main page carries a high PR score however the inner page the location where the backlink is found will not.
Also it should be apparent that backlinks from pages with higher PR count ‘more’ than pages with lower PR.
The exact algorithm that is used to calculate the precise ‘value’ of high PR backlinks isn’t known – but tests have shown over and over which a single backlink coming from a webpage by using 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 dofollow backlinks is better measured regarding simply how much they have the ability to improve your ranking on search engines like yahoo – because it is exactly what you are interested in acquiring them for, right?
Since Google (along with other search engines like yahoo) are focused primarily on providing the most accurate and reliable google search results as you possibly can, using backlinks to influence 94devppky results is one of the types of enhancing the longevity of those results.
And considering that generally high PR websites are fairly reliable and won’t just farm out links like another websites do – search engines have a tendency to take that into consideration.
It isn’t a lot of a stretch to figure that while the need for mass backlinks from low PR webpages might decrease with time, the price of having some backlinks from high PR webpages is just not likely to. Granted, it is impossible to calculate what search engines like google will think about in their algorithms in the future, however it is a safe bet how the logic behind why high PR backlinks count for ‘more’ will remain the same.
Bear in mind that although ‘PageRank’ can be a grading system used only by Google – other search engines happen to be proven to employ similar grading systems and incredibly often pages with high PageRank find yourself doing well on these other systems at the same time.
