I've just started running link campaigns for my websites. My goal is to have 10 incoming links for each page on my website. I think roughly 15 pages on each of my sites. Assuming all pages of the pages that I'll be getting incoming links from have NO PR in the pagebar, how many of these types of links will it take to equal PR1 on a page? 100 or so I imagine, but I'm just guessing. How many of these pages with no PR on them will it take to equal PR4, etc? I know the goal is to find high PR pages to link to me, but I give up, instead I'd like to just go with whatever I can find and let me tell you all of them are PR0 or grey in the PR bar. I know, i know, sometimes grey means the site isn't in the index or it's penalized.. But most blogs that I get the links from, have PR2 and up on their main page. Then when you visit their post, it too will have PR1 or higher, but when you click reply and see the comments, that page never has PR on it, very rare to see it like that.
Google's algorithm has no black and white guidebook to tell us what PR a certain page will be awarded. Each of these 100 no pr links could have other varying factors, like the associated keywords on the page you're linking from, as well as age of the domain, and the domain's own backlinks. I'd say your estimate is about right though, 80-120 links to equal PR 1.
There are also different PR ranks inside the ranks so you would never know how many it would take. One site might be a PR0.99999 and another could be a PR0.00000 and both would show a white PR0 bar.
It depends on so many factors. Fi if you have a link from a strong pr7 site that has no outerlinks but to yours you will get a pr4-pr5 within 1 or 2 updates. Maybe using tnx.net or digitalpoints coop is an option instead of trying to find blogs with pr
Digital Point co-op gave me hundreds on inlinks but did nothing for my SERP position. Google has discounted it like many other top link exchange services.
Tnx has no footprint so it's not possible to identify them as linkexchange. I saw in a pdf about linkbuilding that digitalpoint has a 1pixel image system that's used to calculate the weight but that way it's also a way for Google to filter those sites out
