Does PR depend upon Age of the Domain name ?

Does Age factor effect Page rank ?.

Is PR update over ?

 

Update is over. Age has no effect. PR, unlike wine or cheese, does not get better with age. You just need to keep updating your site and keep building strong links to it. I think the first one is having more influence than the second one these days.

 

only quality and quantity of links.

 

I honestly think the days of checking PR are over. My sites have gone through serious loss of PR but still rank very high and traffic has increased.

 

will tend to agree with yaffer.
traffic on one of my sites which dropped a rank has literally skyrocketed in the last week or so.

its the traffic that matters, not any green bars.

 

PR update is over, but noone knows for sure when the next update will be, by previous experience, it could be in 3 months....but with google always doing its own things, there could be another 1 in a month

 

I hope there is another soon! I went from PR0 to PR4 on a brand new site (1.5 months), and of course, the one site I was hoping would gain, lost!

 

Backlinks are very important !!Especially quality backlinks

 

I've had one single site with 1 backlink from a trusted forum gain PR4 after registering it for 2 years. With 1 year left AND more backlinks, it's dropped to PR3. Google with its registrar capabilities may value longer durations (than 1 year, at least) on websites.

 

I have read that before; that Google takes registration length into consideration. I wonder if there's any truth to that?

 

I would say.. age *MIGHT* be taken into consideration for PR .. as google haven't revealed anything about PR calculations so we cant' b sure enough.

 

Age isn't an issue, it's far more likely that the linking page either added more links, thus passing less on to you, or the pages linking to them added more links taking the PR from say 4.9 to 4.1 and passing less on to your page.

 

That's rubbish, we know exactly what their PR calulation is,

PR(A) = (1-d) + d (PR(T1)/C(T1) + ... + PR(Tn)/C(Tn))

Or to simplify,

PR of a page = The sum PR of all pages linking to it / number of outgoing links from the page x damping factor.

The damping factor is unknown, though usually guessed as being around 0.85

As you can see, none of this has anything to do with the age of sites, links, quality of content, quality of links magic beans or other pixies that I see people all quoting as fact.

 

Excellent point! Very interesting...

 

Thanks, most of you guys answered my question.

When can we expect the next PR update ?
Does outgoing links decrease PR ?

 

No, you can't lose PR from a page, the amount that it can pass is diveded amounst all the outgoing links from the page, the more links then the less it passes to each one.

 

I think Google has reintroduced the sanbox effect to a higher level. New site getting high PR are boxed. Old sites drop in PR are really skyrocketing. That said, I would say still try to optimize for PR as the sandbox is a normal process. This is, however unfortunate, because if you have niche site that no one else has, you still suffer in the serps because of google's ridiculous sanbox.
