Page Rank Calculation 18 medium with 50 oubounds PRx = 1 PRx 3.559 medium PRx with 50 outbouns PRx = 1 PR(x-1) 0.607 medium PRx with 50 outbouns PRx = 1 PR(x-2) 101 medium PRx with 50 outbouns PRx = 1 PR(x+1) 555 medium PRx with 50 outbouns PRx = 1 PR(x+2) If you want to revalue the total outbounds linkyou divide 50 by the links. 50/TOL = links So if you have a link that has 25 TOB it is the same as 2 that have 50. If you have a link that has 100 TOB it is the same as 0.5 that has 50. [EDITED] In general inbounds to most sites come to the home page and most sites have a fully meshed link structure. With these types of sites you can get an idea of the PR value of the home page by looking at the subs. When you channel PR and/or have a good number of your inbounds coming to a sub pages you will not be able to tell with as much certainty the strength of the home page PR by looking at the subs. [EDITED] PRx and the subs are PRx you have a strong PRx on the home. If your subs are PR(x-1) you have a medium PRx home page. If you subs are PR(x-2) you have a weak PRx home page. You many want to read my article Page Rank Calculation where I cover the above rules. Also you will want to read Wafkers Google PageRank, & How to Get It and look at his chart from which I have based my figures.
Interesting idea Bob, but the fact is that assuming that there are 50 outbound links from each page, and that the log base of toolbar PR is 5.5 are both totally unsupported or in other words just a plain old educated guess, and thus reaching conclusions such as the above based on such data is not very helpful. The PR value of the home page has no fixed relationship whatever with the PR of the internal pages and thus a low toolbar PR5 page could well have an internal page with a toolbar PR of 8. From this it can be seen that the PR of the internal pages is not be a reliable indicator of information regarding the homepage. More research and thinking are in order IMO.
The PR of pages within a site are divided equally between all the pages and then some weight is given to the pages with most links to them from both internal links and external.
Mel: In the post your probably notice that I made room to revalue the links if they had less or more than 50 TOL. Google doesn't tell us what the log base is but it is generally accepted that there is. Wakfer uses 5.5 in his chart, Sobek uses between 6 and 7. The results of Wakfers chart have been compared to what the results are on the web and he confirms that the results are very similar. In fact I am wondering if that is the way he came up with his figures. Reverse engineered them so as to say. I probably should have noted for the high, medium and low values that this is the case in with most sites seeing how most sites get links to there home page. It is a fact though if you have a weak PRx on your home page and your links are mostly or all coming into your home page that if you subs are PRx also that indicates the PRx on your home page is strong. If the sub are PR(x-1) medium and PR(x-2) they are weak.
This is a chart that attempts to compare true PR with toolbar PR, so what web results can you compare with when there is no True PR shown. The problem with trying to generalize an estimate in which we both agree that all of the factors are probably in error (the number of links on the page, the actual value of True PR, and the scale of the graph) is that the result could easily be out by an order of magnitude, and that being the case publishing something that on casual inspection seems to say this is the way it is, will at best be confusing. While it is probably true that most sites get most of their links to the home page, it is not true that most sites internal linkage is the same. For instance a fully meshed site should have equal PR on all pages whereas other linking patterns may concentrate the PR in the home page or any other page you choose. If there are more links to an internal page than the home page the internal page may in fact have a higher PR. The problem with this type of post is that six months from now it may have been quoted in a hundred other forums and it may be accepted as an urban legend that you can see whether your home page PR is a high or low PR by simply looking at the PR of your internal pages.
for the non math inclined, we need a pr calculator that you plug in a URL, it analyzes it and tells you how many links you need to go up to the varying pr levels
TOPS30: The ThinkBling utility was based off Wakfer's chart also. Mel: The web results of course are compared to the toolbar PR as stated. I have not agreed that all the factors are in error. I will agree that they are not right on. In some thing as broad as the internet you have to generalize some things. Most web sites have a fully meshed link structure. Most web sites have most or all of their links to the home page.
Its fine to generalize, but in that case it should be clear that you are generalizing. While it is true that most sites have most of thier links to the home page (certainly never all since internal links count too) most websites do NOT have a fully meshed link structure, in fact it is almost impossible to do with a site of over 100 pages as a fully meshed structure requires a link from each page to every other page.
Mel: I agree, and I changed that paragraph to refect that. Well I think that most sites on the internet are smaller and have a link structure that is fully meshed. I can change wording to reflect that.
Hi Bob, i just found this post on one of search engines... it's 2 years passed since this post was submitted. I think it's a good time to look back... so is this still the same technique googl-e uses to rank pages? or their algorithms has changed a lot?
>>>so is this still the same technique googl-e uses to rank pages? or their algorithms has changed a lot? This discussion was mostly about how many links it take to get a PRx. As far as ranking pages most hold (besides Matt Cutts) that Pagerank has little or no ranking weight. I think 2 years ago it perhaps had more than it does not. But most of my posts on Pagerank didn't have to do with where it had ranking weight or not just how it worked.
