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.

PageRank flow and distribution?
I'm confused about PageRank flow inside a domain.. Please provide me with an well explained guide about flow of Pagerank as I know, i think it flows from homapage to internal pages and then internal pages to homepage. I think I'm wrong. Also, every page has its own PR, if I give backlinks to external website from my internal pages, is it going to impact the homepage's pr and authority? Highly confused.. 😕

What are we doing wrong with Rich Snippets?
So, a client webstore has rich snippets on all products, and it seems they are working fine, and are showing up, the only problem is, that the price for an article is not showing up. The part of the code, that shows the price is this: Redna cena:
Technical SEO | | Red_Orbit
29,99 € Is the problem that we have the itemprop="price" in a meta tag? I've read around the internet that if you have a lot of meta, this can be a problem.... Can we change it into: Redna cena: Would this work, or is there another thing that we can try? The URL for this article is http://www.bigbang.si/igre/sleeping-dogs-le-x360-4989980 -

I changed the domain and structure of my site,is there anything I can do to help speed the recovery in SERPs?
I change the domain of my site in March (pretty much exactly when Panda hit, by coincidence). Our search traffic has dropped by 90% in that time with little recovery. In webmaster tools it shows about 400,000 pages on the new domain and about 85,000 still indexed on the old domain. I set up custom 301 redirects to all of the new pages on the new domain so everything that was moved has a good one hop redirect. I've been told that the only thing I can do is sit back and wait for everything to finish transitioning. The problem is that it has been 5 months of poor traffic, which means 5 months of slow sales. Is there anything I can do the speed up the transition?

Is this keyword strategy totally wrong?
I have a Driving School website www.1stclassdriving.co.uk. The site is structured geographically with one page per Area
Technical SEO | | Brian_Worger
(post code) and one page per Driving Instructor. There are links from each Area page to the instructors
working in the Area. The principal search keyword that I want to optimise on is
"Driving Lessons" The thinking was to target each individual Area page for
"Driving lessons in xxx" where xxx is the particular geographic area
and each particular Instructor to "Driving Lessons in yyy" where yyy
is the main town . The ideal would be that a search on "Driving
Lessons" would pick up the root page - search on an area, say "Driving
Lessons in Croydon" would pick up the Croydon area page and a search on a
town, say "Driving lessons in Mitcham" would pick up the Instructor
that covered that town page. However having read Rebeccas Keyword research guide I am
concerned that this strategy is wrong because of the volume of pages that use
"Driving Lessons in xxxx". Does this fall foul of "Keyword cannibalization" ?
and if so what is the best way of being able to achieve our objective?0
