I've been reading about PR being determined by how many links you have to your site from sites with a higher PR than yours. I was wondering if all links count? For example, if I have a PR5, and I: - Leave a comment on a PR7 blog and a link to my site (PR5) - Posting a link on my Myspace page (PR8) to my site (PR5) - Paying for an ad button on a site (higher than PR5) Would these all serve to increase my PR, or do the links have to be "real" links?
There are several factors involved (besides PR) in how much a link counts. Only Google knows the exact formula. Also, many links now have nofollow tags attached to them, which makes them worth almost nothing even if they are from a high PR page.
I think you are a little confused. Myspace homepage has a PR of 7, but your personal myspace page has a PR of 0 most likely. Other notes: If you buy a link from a high PR site, make sure the "page in which the add is displayed" has high PR. If your site is considered unrelated to the site in which you buy or post the link it could yield you little to no value. A PR7 probably is split into 5-10 pages. If you check the PR of page 5-10 there will most likely be a PR Of zero, considering little traffic makes it all the way to the end of that page
Thanks for the info, I understand what you mean about Myspace. How do they determine if a site is related? Leaving comments on Engadget, TMZ, and other high profile blogs (both of those are PR7), would be helpful?
Leaving comments on do follow blogs will help you to improve your page rank but some blogs are no follow, leaving comments on these blogs will not help your page rank.
Most inbound links are good if you can get them...you can't necessarily judge how much each link will do for you there are many factors going into how powerful each link could be.
If you are using Firefox, then right click on the link and click on properties ! other wise install an add-on or even view the source code... Hope i helped you some how?
I'm using Firefox, I went to a few links' properties but all it says is the address and that it'll open in a new window. Does that mean it's do-follow?
Looking for "nofollow" means looking for that <meta name="robots" content="nofollow"> tag in the <head> section of the site's HTML? (Page => View Source)
So for example Engadget doesn't have it, so every comment I left on their blog would count as a link from a PR7?
it depends if its follow or no follow links, no follow links dont count but if they are in a good visible location thay may count as you will get clicks out of them.
If you install this firefox extension it will highlight all no-follow links in red. Without a plug-in you would need to read through the source code of the page. http://www.zacharyfox.com/blog/free-tools/nodofollow-a-firefox-extension
Nice nofollowfirefox plugin, will definately be giving it a go, i've heard that even with the nofoloow tag links still have a bit of weight but not sure if there is any truth to this.
do a search for google pagerank formula .. and you can get the formula .. alternatively search for "Page Rank & Link Quantity Calculation" .. will show you how many inbound links of a certain PR to get a certain PR. For example you need 13,442 PR1 links to get a PR5, based on an 85% median value and average of 40 outbound links from those pages.
