I know this is a lame topic but I was wondering if anyone knew the relative worth of page rank to other page ranks. I.e. What relation is PR5 to PR4, in that is 2 PR4s worth a PR5 [were talking link weight] Or is it on a logarithmic scale? In that PR5 is worth 10 PR4s and 100 PR3's etc? Anyone have any [logical and reasoned] ideas on this? Cheers
Nobody really knows for sure. Most people seem to think it's logarithmic, or at least something close to that. I can say for sure that 2 PR4's DOES NOT equal 1 PR5. I wouldn't worry about the actual values so much. Just try to get as many relevant links as possible, and from the highest PR sites as you can and let Google work out the rest.
I'd rather a natural link from an on topic trusted PR6, followed by an on topic natural link from a PR0, and I would not be interested in "off topic" links - but that was not your question. It is logarithmic BTW
Thanks And without going into too much detail thats exactly what im trying to do To come up with a way of calculating the worth of links based on its PR and relevancy. So if we assume a logarithmic scale then 1 PR5 is worth 10 PR4's. But with poor relevancy you'd want more PR4's. I.e. assume relevancy as a percentage between 0 and 1 Then an on topic PR5 link is worth 10 x (1 / relevancy) PR4 Links
I'd take a relevant link over PR every day. If you are trying to make a tool to correlate relevancy vs PR I would give up now. There is one such tool - owned by Google - but that is secret
Giving up isnt in my vocabulary! Anyway it's a much better method for determining link value than alexa and text link ads made millions off that lol
Well, you could look at Pay Per Post and take that into consideration. Just one post is based on PR and Alexa ranking. Smartpagerank has valuation tool. Kind of cool to look at anyway.
It's not as simple as a PR5 is worth ten PR4. Since the Toolbar PR represents a scale of a "True PR," the difference between a low PR5 and a high PR5 can be greater than the difference between a high PR4 and low PR5. Another complication is that you never know the real-time PR of any site, especially right now when the update is delayed so long. At this moment, PR is the roughest of guides to link strength. It's there to give a general idea. Calculating PR is a guessing game even for the "experts," because although the formula is there, you are not equipped to manually calculate the value of all the links in real time, or the actual True Rank vs. TB PR, for example.
amanamission: your very right, its a rough guide, and not perfect, however as far as im aware there is no better way to gauge the strength of a page's outbound links! Unless you know something i dont?
Which one is relative / more relative? Which one has higher quality content? If it happened to be the PR0, I would take that one.
