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.

Wrong image shown to represent brand in mobile search
The image I’ve attached is a screenshot of what shows up on mobile when I do a branded search for one of my clients. We have a Youtube video on the homepage featuring Harry Connick Jr. The video is directly under the hero image on the homepage, and the thumbnail for the video is the image that Google is pulling into the SERP. I don’t want this image in the SERPs. I’ve marked up the logo with schema but that doesn’t seem to be helping. Is there any other schema markup I can use to remedy this? What else I can do to influence which image Google pulls? zVfvz

Google Displaying wrong URL but correct page title and description in SERPS
Hi. Our second highest performing page on Google is messed up in the SERPS. This is our login page. It always ranks high. It still does, but the URL is incorrect. Google is referencing an old redirect that was for a one off campaign from January 2014. This page has long been redirected. But now the vanity url for this page is what is displayed in Google. The link goes to our login page but once you log in it redirects you to a page saying the offer has expired instead of your account details. This is a huge issue for us. Can anyone shed some light? I'm having a rel canonical added since this page is used for a lot of vanity deeplinks.

To avoid errors in our Moz crawl, we removed subdomains from our host. (First we tried 301 redirects, also listed as errors.) Now we have backlinks all over the web that are broken. How bad is this, from a pagerank standpoint?
Our MOZ crawl kept telling us we had duplicate page content even though our subdomains were redirected to our main site. (Pages from Wineracks.vigilantinc.com were 301 redirected to vigilantinc.com/wineracks.) Now, to solve that problem, we have removed the wineracks.vigilantinc.com subdomain. The error report is better, but now we have broken backlinks - thousands of them. Is this hurting us worse than the duplicate content problem?

Multiple Domains, Same IP address, redirecting to preferred domain (301) -site is still indexed under wrong domains
Due to acquisitions over time and the merging of many microsites into one major site, we currently have 20+ TLD's pointing to the same IP address as our "preferred domain:" for our consolidated website http://goo.gl/gH33w. They are all set up as 301 redirects on apache - including both the www and non www versions. When we launched this consolidated website, (April 2010) we accidentally left the settings of our site open to accept any of our domains on the same IP. This was later fixed but unfortunately Google indexed our site under multiple of these URL's (ignoring the redirects) using the same content from our main website but swapping out the domain. We added some additional redirects on apache to redirect these individual pages pages indexed under the wrong domain to the same page under our main domain http://goo.gl/gH33w. This seemed to help resolve the issue and moved hundreds of pages off the index. However, in December of 2010 we made significant changes in our external dns for our ip addresses and now since December, we see pages indexed under these redirecting domains on the rise again. If you do a search query of : site:laboratoryid.com you will see a few hundred examples of pages indexed under the wrong domain. When you click on the link, it does redirect to the same page but under the preferred domain. So the redirect is working and has been confirmed as 301. But for some reason Google continues to crawl our site and index under this incorrect domains. Why is this? Is there a setting we are missing? These domain level and page level redirects should be decreasing the pages being indexed under the wrong domain but it appears it is doing the reverse. All of these old domains currently point to our production IP address where are preferred domain is also pointing. Could this be the issue? None of the pages indexed today are from the old version of these sites. They only seem to be the new content from the new site but not under the preferred domain. Any insight would be much appreciated because we have tried many things without success to get this resolved.
