Lets say I have a PA 50 website, and I just got a PA 60 link from another site. Is there any way to project, mathematically, what that new link will do to my page's authority?
Would the formula look something like this?
New PA = Current Page PA + ((New Link PA*dampening factor)/Total number of links on new page)
In the absence of a mathematical model to predict shifts in PA, how can you be confident that a specific action will help you progress towards an authority objective?
