Is there anything wrong with this pagerank diagram?
-
Hey guyz,
I've asked many question today but forgive me :D.
I just want to know is there anything wrong with this diagram http://mygreatname.com/google-pagerank/images/google-pagerank-algorithm-03.gif
Because page 1 has 3 outgoing links but you divided 2 and page 2 has 2 outgoing links but you divided only 1. Or do I miss something?
Thank you. -
I believe the actual calculation comes from Google's internal PR measure, so if you used Toolbar PR, it would be scaled in appropriately. For example, a page with TBPR=4 would only pass 33% more equity than a page with TBPR=3 (if you treat TBPR as linear), whereas it should actually be an order of magnitude higher (we're not sure what power Google uses).
Technically, you can't calculate PR without the entire link-graph, since the maximum values are set from the link graph, and the calculation is iterative. On a small scale, you could just pick a log scale to use and approximate what happens.
I guess I'm not sure what you're trying to accomplish. Beyond a tutorial view, so many factors are laid on top of PR, that even if you could calculate the true values, they would only tell you a small part of the story.

So you saying that if my page PR is 2 which is logarithmic based 100
And If I link from this page to another page which is PR 0 .
So what my contribution to the PR 0 page is you say 100/2=50. ?
Or just plain logic PR 2 / 1= 2 (Because there is only 1 link ) ? -
Sorry, I'm a little confused - I see dividing by 3 and 2 in the diagram you attached. Are you saying there's somewhere on our site where we're giving the wrong numbers?
Keep in mind that Toolbar PageRank is a 1-10 scale based on a logarithmic transformation of a continuous scale (or at least, one with much more precision). Since PR is probably calculated on that hidden scale, using Toolbar PR in the formula probably doesn't work as intended.

SEO impact of an iframed blog is very low ? Right or wrong ?
We're thinking about adding a blog to our site, but our CMS blogging features are not good. Someone suggested using a wordpress blog and putting it in an iframe on our site. I replied that all the SEO impact of our blogging efforts will be lost because of the iframe. I am right or wrong ? If I am right, could you suggest better alternatives ? Thanks in advance !

IIS 7.5 - Duplicate Content and Totally Wrong robot.txt
Well here goes! My very first post to SEOmoz. I have two clients that are hosted by the same hosting company. Both sites have major duplicate content issues and appear to have no internal links. I have checked this both here with our awesome SEOmoz Tools and with the IIS SEO Tool Kit. After much waiting I have heard back from the hosting company and they say that they have "implemented redirects in IIS7.5 to avoid duplicate content" based on the following article: http://blog.whitesites.com/How-to-setup-301-Redirects-in-IIS-7-for-good-SEO__634569104292703828_blog.htm. In my mind this article covers things better: www.seomoz.org/blog/what-every-seo-should-know-about-iis. What do you guys think? Next issue, both clients (as well as other sites hosted by this company) have a robot.txt file that is not their own. It appears that they have taken one client's robot.txt file and used it as a template for other client sites. I could be wrong but I believe this is causing the internal links to not be indexed. There is also a site map, again not for each client, but rather for the client that the original robot.txt file was created for. Again any input on this would be great. I have asked that the files just be deleted but that has not occurred yet. Sorry for the messy post...I'm at the hospital waiting to pick up my bro and could be called to get him any minute. Thanks so much, Tiff

HELP: Wrong domain showing up in Google Search
So i have this domain (1)devicelock.com and i also had this other domain (2)ntutility.com, the 2nd domain was an old domain and it is not in use anymore. But when i search for devicelock on Google, the homepage devicelock.com does not exist. Only ntutility.com comes up. I asked one of the developer how the redirect is happening from the old domain to the new one and he told me its through a DNS forward. And there is no way to have an .htacess file to set up a 301 instead. Please help!

Wrong page version in the index
Hi, my site is currently accessible through URL with and without www. The Version with www has 10 times more Backlinks (PA 45 vs 38) but is not listet into the google Index. As far as I know there was never made a google Webmaster account or declared otherwise the version without www to be 'cannonical'. Basically I think that for SEO reasons it would be much better to declare the with www version to be cannonical and redirect the without www version to it. My questions are: Do you have an idea why the with www version is not indexed?

How long does Google usually take to change the version in the index?
Do I risk my site to be thrown out of the index for some days untill the change is made? Thanks in advance.0 -
HTML Forms Dilute Pagerank?
Today, we have way too many links on our homepage. About 30 of them are add-to-basket links (regular html links) pointing to a separate application. This application 302 redirects the client back to the referring page. I have two questions: 1. Does the current implementation of our buttons dilute pagerank? Bear in mind the 302 redirect. 2. If the answer to the first question is yes, would transforming the buttons into form buttons change anything to the better? We would still 302 back to the referring page. I know Gbot follows GET forms and even POST forms, but does GBot pass on pagerank to the form URL?

Pagerank mystery
Hello SEO brethren - I've got a mystery I'm trying to solve. I work in house SEO at http://www.uncommongoods.com/ Our home page is a Pagerank 5. All of our sub-pages are Pagerank 0. Even this one below which has 276 links from 57 domains: http://www.uncommongoods.com/product/recycled-wine-bottle-platters Any clue what is going on here? Is a PR 0 typical for a page with this many links / linking domains? Thanks! -Zack
