Link Juice (PR Weight) Flow And The Importance of Link Age

For you to make the right decisions regarding the effectiveness of your link building campaign, you should know that NOT all link juice (PR Weight) is passed to your website at once after the link is built. In fact, for most links it will take up to 6 months for the PR Weight to be passed to your website for 100%. Take a look at the table below showing the percentage of PR Weight passed from PR4-PR6 backlinks during the first 6 months of use.


Month of Use% of the Passed
PR Weight
1st10%-15%
2nd20%-30%
3rd50%-60%
4th65%-80%
5th90%-95%
6th95%-100%


As you see, this progression is gradual. Please note that the higher the PR of the backlink is, the longer it takes for PR Weight to flow to your website. For example, for PR7 and PR8 backlinks this period can be from 6 to 12 months. Whereas for PR1-PR3 links this period is shorter – from 1 to 3 months.

That’s how Google determines weather the link is natural or not. If it appears for a few months and then disappears, your website rankings won’t even change. Google only trusts old backlinks that stay alive for long. That’s what proves to Google they are real.
