speculation is about "downweighing" of recips and director listings

Similar idea here. Last month Matt Cutts talked about changes in the way backlinks were "being weighted". This is the first toolbar PR update since then, so the first chance of seeing what that might mean. Now "being weighted" could also be talking about other kinds of backlink infulence and not specifically PR, but I still think it's a good guess.

3 sites dropped from 4 --> zero on most dc's

Surprising as in terms of influence Holland is the gateway to europe....

2 major SEO sites and one major Keyword Tool site have gone from PR7 to PR6...anyone notice other sites in SEO industry loose PR?

I am seing that too.
Although PR drop apparently has no impact whatsoever on select websites.

I also find that some sites that kept their PR value are certainly not the most trusted in the industry - many have backlinks from paid textlinks or simply from their own network of websites.

I was hoping more realistic PR values someday, apparently GG doesn't agree - is there a point keeping the toolbar PR at all? Is this only to fool webmasters, I seriously start to believe so.

In a way, if GG is playing around with toolbar PR values while keeping real values for themselves they will prevent the whole link scheme from affecting their SERP AND at the same time they don't have to tell us that's just a random value on our toolbar.

hey I was thinking: funny that it affects SEO sites especially now that Google bought an SEO firm no?

So is the first wave removing PR value then the 2nd wave dropping competitors? ...not all at once otherwise people will notice :)

Ok maybe I am paranoid, but seriously I've seen lawsuits for less than that :P

could you elaborate on your claim and how did you come to this conclusion?

my SERP ranks leapt immediately after the PR update propagated - anyone have any thoughts / comments?

...just a follow up to my comment above (yesterday) and Tedster's reply - you were spot on Tedster, no change in ranks due to the TBPR update - just the visibility on the Toolbar. (but with a 4 --> 6 jump, and a bunch of other nice improvements on interior pages, I do have a big smile on my face haha). Tks.

i still think Pagerank is just a piece of what links carry, so i don't think about a devaluation of link exchange or similar in Pagerank. but of course, and not since today, there's devaluation when it comes to ranking.

many people (not only here at WebmasterWorld, actually) are noticing a -1 drop in TBPR.

well, there are at least 3 possible causes for this, imho:

1) pages linking to ours have less pagerank, so there's less pagerank to transmit.
2) pages linking to ours have more links in it, so a smaller portion of pagerank is transmitted to every single linked page.
3) pages didn't really lose pagerank. just other websites gained more.

remember real pagerank is not 0-10, but 0-infinite...

Yes PR Final Update Finished this morning.

Which PR update? :-)

Honestly I'm in a big doubt now that there has been a real TBPR update..

Reasons:

- The PR values we see at present on the Toolbar might be inaccurate. Our kind fellow member Adam Lasnik wrote yesterday [webmasterworld.com]:

...If, however, your PR has dropped to zero AND you've not seen any significant loss in traffic from Google, rest assured that this is most likely a PR-reporting (PR on Toolbar) error; ...

Which could means that the changes we see at present on the TBPR values might be not accurate.

- Though we have noticed the start of changes on TBPR for 4 days ago, there hasn't been yet any confirmation from Google that a TBPR update has started or has taken place.

- We might have been witnessing a Bad Data Push in an attempt to update TBPR.

0-infinite

erm..actually its finite...

yes, ok, it's finite. but potentially infinite.
however, let's put in an easier way: do you think real pagerank goes from 0 to 10? or does it arrive to a "sligthly" higher number?

Real PageRank is calculated out to many decimal places - it's not just a simple integer. So the number of decimal places in real PR is potentially infinite.

Page Rank can be understood as a probability distribution - the probability that a "randomly clicking surfer" beginning on any arbitrary web page will end up on the page in question. The toolbar gives us integers from 0 to 10 as a convenience - but really, just like any probability, the highest PR is actually "1". It's as though real PR is multiplied by ten and then the trailing decimals are truncated to give the user-friendly, simple integers that we see on the toolbar.

tedster..interested in how you make pr infinite...

pr is a measure of your share of the 'power' of the internet where a share is decided by your share of the total number of links....to my understanding for any given iteration the number of pages on the internet is finite..therefore pr cannot be infinite since it cannot exceed the sum of the total...that total sum is a fixed number..if that number was infinite everyones pr would be infinite...

thats how i understand it anyway! :)

even by your own explanation you state the total as being one....if the total is one how can the pr be infinite when the total of everyones pr must be 1

I went from a 5 to a 3 and I know why as I write articles and add revelent links to other sites to verify or show trust in the article I do not use follow tags so I assume I am bleeding quite bad.

I admit it hurts to see a 3 but I know the reason why and feel PR is just something we look at and a small part of the overall picture....I quit chasing the bar and now focus on quality content to bring a customer back for information.

tedster..interested in how you make pr infinite...

I wasn't saying that, soapy. Guess I wasn't clear enough. Calculating to an infinite number of decimal places still gives a finite number.

Possibly the confusion is coming in between maximum total PR on the web and maximum possible PR for a given page. The maximum possible PR for any one page is 1 (turned into 10 on the toolbar). There is no maximum for possible total PR on the web -- but at any given time, as you say, it is always a finite number.

Sorry for going off-topic again. Now back to the regularly scheduled PR Update thread...

submitx
I believe I know your representing company. I believe that your website's PR has dropped to 5 and some similar stuff has happened with us.

I believe that Google has completely changed the way they used to give weight to the inbound links.

Some Observations

Links from all pages like resources, links, etc..etc... were disrespected
Links coming in from Blogs, Articles, Forums got cached in Google Index
Google disqualified links below PR 2
Many more awaiting :(

I have been having a SEO company work with on one of my sites and their PR went from 5 to 6. Looks like they are doing something right. Hopefully, mine will shift as well.

It could turns out that it's a google engineer who has grabbed the 72.14.203.*** datacenters for himself to tinker around with [webmasterworld.com] :-)

Yes. May not be accurate and possibly they may not fix it too like link operater ;)

I think it's still being played with. I didn't see any changes at all on any of my sites or my client sites until this morning, and I've got a ton of new pages now showing PR which were 0 before, and even more where it says PR is unavailable. And my GWT says it doesn't have the data for highest ranking pages, where yesterday it actually did report a page for May. I don't think it's all shaken out yet.

No changes in SERPS, and traffic is way up, if anything.

Almost all my sites are updated with different PR lesser than expected still I believe there is some link data is missing in this update or the cut off time is more than one month. However I am not convinced that all my new PR will be refreshed again.

Is it some sort of paidlink filter discounted too many natural links? Anyone has similar ideas?

Seeing a lot of PR unavailable on certain interior pages across a large swath of unrelated sites...if it the update is complete, it is broken; if it isn't complete, then it is interesting the pattern it took for updating TBPR.

Is it me or are pages with the most outgoing links the one without TBPR right now?
