How many PR4 backlinks to equally one PR5

We are just in theory. I have one backlink from relevant PR5 site.

How many PR4 backlinks from relevant sites I need to have equally effect?

 

google secret xD i have no clue

 

You really can't equate them like that, each site is going to be weighted individually by google.

 

Because somewhere I read that is about 100 but I don´t know where and I want to know what DP members thinks.

Hey,
Only Big G know that

 

Just an opinion. You will not have a PR5 Juice from PR4 site.

 

I agree with gary although this would make things difficult in the early stages of google if this was the case. Woudn't they have to set SOME sites to a higher page rank early on for that theory to work? I am well aware that Google has long since surpassed that obstacle. They probably calculated it differently in the early days. And thanks for the post on how page rank is updated that was invaluable to my current link building project. I'm sure there are many other factors that google takes into consideration aside from the ones that were mentioned, it's a great point of reference for link building strategies

 

It depends on the link juice.
