If I have interpreted this correctly, I can see why getting 1 PR10 backlink is more efficient than trying to obtain 10,000 PR 0 or 1 backlinks. It would be easy enough to get PR 0 or 1 backlinks but to get a few PR 8 - 10 backlinks would require alot of effort and patience.

Man I love these charts. They totally apply to what I explained in another thread "Clearing up some things about PR and SERP ranking", so I quoted these in that thread and included a link to this thread.
I think getting a backlink on a PR10 site is fairly unlikely though. Even getting on a PR7 page or above is going to be very hard for most of us. But even staying within the range of what's realistic, it's still pretty impressive. One backlink on a PR2 page is the same as getting 101 backlinks on PR1 pages. Even more impressive, one backlink on a PR4 site is the same as getting 3044 backlinks on PR1 pages.
So getting backlinks on some higher PR sites can make a dramatic difference in the number of backlinks needed. That doesn't mean getting backlinks on PR0-PR1 sites is bad, just that the higher the PR of a page the more valuable a backlink on that page will be for your site.
Thanks for sharing.
Here's the other one:
Actually according to the chart I think you meant "1 PR10 link equals roughly 2,800,000 PR3 links".

Glad I could help everybody visualize the whole thing. I'm a very visually-oriented thinker and it helps me a lot to put things in perspective when I see things like that and not just look at numbers.
About what I said:
1 PR10 link gives PR8.
2,800,000 PR1 links give PR8
Hence 1 PR10 = 2,800,000 PR1 in terms of the link juice ti provides. What you say is about the fact that 2.8mil PR3 links will give you as result a PR10 page. NOT that 2.8mil PR3 links have same effect as 1 PR10 link.
You can find PR7 pages you can get links from. Many are spammed to death but from time to time I find some gold ones with no external links on them.
Just for everybody to get an idea, when I got a relevant PR5 link from a PR7 domain to my site, rankings for ALL keywords jumped about 20-30 positions for those that I was ranking on page 2 and 2-3 positions for those I was ranking on page 1. Also took several main keywords from #3 to #2 (average competition keywords).
Also, I managed to take sites on #4 in google for low to medium competition keywords just with 9 high-PR links (1xPR7, 3xPR5, 5xPR3) and about 100 shitty ******** links (no PR).

That chart is synthetic. That means it idealizes all other parameters. It is also an estimate not an exact thing. In reality, when it comes to the effect on SERPs, having a relevant PR1 link will have more benefits than having a non-relevant PR1 link. At the same time we have to realize that we always benefit most from a mix - high PR links even if not relevant will give a lot of domain trust, many relevant low PR links will increase relevance, even more no-PR or very low PR links (relevant or not) will increase domain and IP diversity, hence increasing even further domain trust and SERPs.
I have stopped looking at PR as a good measure of success in SEO when I managed to outrank with a PR3 homepage of mine reviews.cNet.com which was ranking with a PR5 inner page and it was a PR7 domain (subdomain). When you do proper SEO you know it because you outrank competitors with sites that seem weak compared to them. cNet did 3 itterations over their content, layout and content structure, they left bad comments on my site and still didn't outranked me. And I wasn't even doing SEO on that site anymore... it was doubling in traffic and revenue every year with no help from me because it acquired inertia.
Now, if you manage to do that for the root keyword and you also have an EMD, you become almost unbeatable. The effort required to outrank you will almost make it not worth it because you have everything helping you. Every single factor that matters.

That's why when your making evaluations on things like this you have to make all other factors as close as possible. If you want to compare the effects of backlinks on different PR sites, (such as benefit of 10 PR1 pages compared to 1 PR2 page) you need to make the comparison with relevant pages for all those links. If you mix links on relevant and non-relevant pages then you're including another factor that can skew the test.

Yeah, I think doing SEO tests is extremely difficult. You don't get exact data because you don't cover all variables so you have a high variation in the findings. You could do a test and find out 100 PR0 links gave you a PR1. But what kind of links were those. Where they mostly links of PR0.001 or more PR0.9. Were they from relevant posts, relevant sites as a whole. What PR did the domains had? What kind of links were those - in text, comment, signature? How many outbound links on that page? How many external outbound links? What internal linking architecture did each site had? And so on. Doing this manually is impossible. Would take you days to map out 100 links and you'd still miss out lots of factors or get some screwed. You can only make a guesstimation in the end. Still useful but not exact or a science.

Exactly. That's why it's so important to understand what some things are actually doing. It's easy to see statistical correlations sometimes that can lead people to wrong conclusions. There's so much interrelated things going on that what can seem like a cause and effect relationship is actually the effect of another factor causing both things.
That's typically the biggest cause of most SEO myths that get passed around. :cool2:
