Any thoughts on this? You can get to the website either way.

This will also prevent search engines from getting confused on which domain your site is.
If you use Apache as a webserver you can do this quite easily with mod_rewrite.
In any case, PR gets transferred when you do a 301 permanent redirect.
Your PR would be "transferred" to that of the LESSER PR page if directed your HIGHER PR page to the LOWER PR page, would it not? G doesn't do things logically.
Haven't figured this one out yet myself...

So, if I add a PR 2 to a PR 1 I end up with less PR than if I add a PR 1 to a PR 2... must be some of that new math - not sure I'm up to it.
PR from one page from another can't be cumulative. If a www version is PR2 and the non-www of that page is 1, if you redirect the weaker non-www to the stronger www your PR isn't going to be 3, it should be 2, that of the stronger page alone. So, inversely if you direct your stronger PR2 version to your weaker PR1 version, the resultant PR is going to be that of the weaker page, PR1. At least this is what I was always told here, and what I've seen in my own experience, unless it takes G months to update this.
Google considers http://www.example.com and http://example.com as two different url's
Does that mean that G will peanalise for duplicate pages?
I can acces my site through 4 URLs:
www.example.com (PR5)
example.com (PR5)
www.greatexample.com(PR5)
greatexample.com (PR0)
The last 2 are redirects from a similar domain name that I'm not using at the moment so I just pointed them at the main site. All the internal links also show PR except the PR0 "site" which has none anywhere. Also DMOZ lists both www "sites".
None of this was done intentionally to deceive G or other SEs, but should I be worried anyway?
Redirect both non-www and www for every version, to just the one place you decide to promote.

PR is an exponentially harder number to achieve. Meaning if PR 1 = 10PTS, PR 2 = 100PTS, PR 3 = 1000PTS and so on. (Or, something close to this effect... Well documented on this site.)
If you redirect a PR 2 (100 PTS) to a PR 1 (10 PTS), you end up with the same number of Total PR PTS (110) as if you redirect a PR 1 (10 PTS) to a PR 2 (100 PTS) Total (110 PTS) neither of these is enough to give you the required 1000 PTS to achieve a PR 3. So, it is correct that in this case 1+2!= 3. But rather, 1+2 = 2.01. (100 PTS = 2, 1000 PTS = 3, 10/1000 = 0.01)
The fact the the tool bar does not reflect this in a short period of time has nothing to do with reality. The reality is the PR coming into a domain is the same amount. What you accomplish by redirecting is to not split that any more, but rather concentrate it on a single version of the domain.
The toolbar that you are looking at is wholy inaccurate, except for a snapshot at a given point in time. (Posted on numerous occasions, and well referenced within this site.)
Does the reattribution of PR take a little time after a redirect is implemented? Yes, absolutely. But to say you are going to lose PR because of which version of your domain you redirect to is inaccurate and misleading.
Will the toolbar be the nice number of green pixels people would prefer anytime soon? Probably not, but again that is a snapshot in time, not reality as of this minute.
I have not seen a post from anyone who knows how PR works that contradicts this. As with some other posts, the interpretation you are applying to PR seems to be inaccurate. Please, take the time to read some of the documentation regarding issues before you post as an authority on them. Remember, your post are read by, and may effect, a large number of people, their sites and livelihood please do them the courtesy of being knowledgeable and accurate.

Rather insulting I must say. I don't recall stating anything was FACTUAL, nor insinuating any "authority" on them. Let's check again......
"Your PR would be 'transferred' to that of the LESSER PR page if directed your HIGHER PR page to the LOWER PR page, would it not? G doesn't do things logically."
Not there, in fact, that's asking a question.
"....At least this is what I was always told here, and what I've seen in my own experience, unless it takes G months to update this. "
Nope, not there either, in fact in that case I even put an important line IN ITALICS, emphasizing (or so I THOUGHT) this is just what I have seen. So please don't go around saying that I'm stating anything of the kind. ~90%+ of the posts on any thread at this site is speculation.
Now, I see you're saying that PR is cumulative in the area of only applying a few decimal points so to speak from a directed URL version to another. That would make more sense because this would explain why I never saw any PR increase after directing one URL version to another. However, the whole discussion regarding the 301 going on during Bourbon was that everyone was directing their WEAKER PR version to their STRONGER PR version to avoid any potential dupe content penalty. This would indicate that doing the opposite (301'ing stronger to weaker) would have negative effects somewhere.
Google is NOT "out to get you" or to destroy your life. They are just keeping things orderly and that's what we need to do.
They truly do sort things out in due order, but the best and safest rule is to "never confuse a bot."
Does anyone know why when you remove or add the www to the domain to find page rank, that pagerank will give you two different pageranks? When I leave out the www in http://www.example.com I get a 0/10 but when I leave in the www, I get a 4/10 rank.Any thoughts on this? You can get to the website either way.
Tami_SEO, I would set up the 301 redirect as already suggested here by some very knowledgeable people. The page rank issue will take care of itself over time. You need to decide to redirect to www or non-www. I redirect to www. I had many non-www that took a long time (>6 months) to get rid of with a 301 in place. My xml sitemap may have helped with that. I think I am down to only 1 non-www now.
This is what I am using, various methods have been documented here many times. I'm open to suggestions if anyone has a preferred method.

Can't believe I saw that. ;) There is nothing orderly about G. They are the quintessential definition of "disorder". [webmasterworld.com...]

And dozens more.

LMAO...
Math is by definition logical.
Maybe a search for 'heuristic algorithm' (that wikipedia site has some good information) would shed some light on why things may seem unorderly to some. Google is not looking for the best site *shock* so it really doesn't matter if yours is... they are looking for the closest match to their criteria. It may seem small, but there is a huge difference between what people seem to think they are looking for and what they are actually looking for.
OTOH...
Maybe the guys at the 'plex' had time to find you in one of their secret manual reviews and really are out to get you.
(8 bil pages, by reviewing 10 pages per hour * 8 hours per day * 1000 people reviewing = 80,000 pages per day * 365 = 29,200,000 pages per year : so 8,058,044,651 / 29,200,000 = 275.960433 years to get all the way through the index once.)

example.com is the default main index page for the root of a site.
www.example.com - the www location - is a subdirectory, not the site root - like widgets.example.com would be
www and non-www are two separate locations in a site. There could be two completely different pages at www. and non-www - just because both may turn up in a browser with the same content showing doesn't mean they are the same thing OR the same location - they aren't.
10 links to example.com is 10 links to the site root default index page. They are NOT links to the subdirectory called www
10 links to www.example.com is 10 links to the subdirectory, NOT to the root index page.
Those are 10 links each to 2 different locations, NOT a total of 20 links to one location - because they are not the same location.
Does that make sense?
The redirect takes care of things while you are doing that, and continues to work for those that you miss or where the owner is unwilling or unable to update.
