Page Rank Calculation confusing me

[Peter Adam]

Assume that i have site with 3 year old and i have pr5. Now i'm going to entirely change the site design as well as different content i have put compare to earlier. Assume that i had social bookmarking site, now its a directory. google will give pr for page. Is that ok?. Then why my page rank is pr5 still? i have changed the page. So page rank will be given to domain name auh? I'm something confused.

Pagrank is updated universally a couple of times a year. Your new PR won't reflect until the next update.

Pagerank is logarithmic.
If one PR6 site is five PR5's (it isn't), then that's the same as 25 PR4's or 125 PR3's or 625 PR2's or 3,125 PR1's.
So don't expect massive PR changes unless your site had experienced really dramatic change.

Keep in mind that according to Google themselves, PR is not calculated based on your content or design, but relies heavily on the quality of links pointing to your site.

So if you have lots of high PR backlinks, links coming from EDU or GOV sites, etc, changing the design or content of the site shouldn't per se significantly affect your PR for the better or worse.

Of course, given that you don't mess things up and end up having lots of 404 errors, an abismal page loading speed, etc. Don't take my word on that, but I guess this may on time decrease your PageRank.

PR depends on the back links,age authority of site and some other factors .

This is all about PR in a brief PageRank - Wikipedia, the free encyclopedia

It should make you get the answer of your question

Whenever Google page rank will update than you can get impact on your site, only design or content is not sufficient for PR, also important factor for page rank domain age, back links, hosting.

Hi Peter,

PageRank isn't assigned to domains, it is assigned to specific individual URLs. It isn't based on the content of your page, it is based in the inbound links to your page. Changing you page's content generally will not effect the PR of that page, however changing URL structure will.

@orvn,

That is not entirely accurate. Real PageRank is calculated at query time and uses the current link graph. So real PageRank is effectively updated immediately following the update of the link graph.

It is only the Google toolbar data that gets infrequently updated. Toolbar PageRank isn't your current PR it is only a snapshot of what it was a sometime in the past.

Hi Don,
Thanks for clarifying my post of the ambiguity. I do understand that pagerank is updated regularly internally and did indeed miss mentioning that in my earlier post.

The PR might change when google makes changes and it happens twice a year.

I'm really appreciate all of your replies. Now i have got a good idea about page rank. My doubts are cleared.
