PR is one small factor in deciding your rank. Although I wouldn't waste my time obsessing about it. There are so many other factors to consider when it comes to where your site is ranked.
The more backlinks a site has, the more "popular" the search engines think it is. The number of backlinks is one of the factors that tells google on where to rank pages in the results pages. The number of backlinks is a small factor, but its still a factor. The better a site ranks in the results pages, the more its worth.
If I wanted to buy a website, I would absolutely not care about the PR. I have seen PR decrease while traffic increased. What I would be interested in is the amount of traffic, ROI, income, CR... I don't think your website is worth more money just because you have higher PR. Not in my opinion anyway.
Absolutely, PR has become the driving force behind so many "SEO campaigns", the number is factored by the amount of links pointing to a site. Now while this is a great idea in theory, it's become worthless in practice. When everyone out there is building links to their site so that it comes up in both PR and in SERPs, can you really believe that because a page has a high rank attached to it, that it's actually worth more money? You can't buy your way to the top of the search engines, and PR should be no factor in the price of a site, or domain name. As said above, look at sever traffic logs, look at the advertising money coming in, look at everything else before even considering looking at the PR.
So PR has some value in itself but doesn't translate into dollar value then. Oh well, I was hoping someone could say if it's a PRx then it's worth $xx. Obviously a good place in a search result will count for a lot as will proven earnings, but I was hoping a good PR would have more of an influence on saleability. Traffic on the other hand is a different story, it seems easy to get, quality traffic is harder. Bother back to the drawing board. I've got a lot to learn yet, anyone got an Asprin? My brain hurts.
I don't care about the PR of a domain if I have the traffic. But I think PR has commercial value too.
it gives more value in your site if you got good and high pr. Lots of site would love to link from your site.
I completely agree that PR is a very small factor in search engine ranking, however I have sold a number of sites and the ones with PR always sell for more - I suppose when people evaluate a site is a factor
i have never really bothered with page rank etc until recently. my site has always had a pr of 3. i have recently started learning about seo etc and started to work on my site, enriching content and keywords, optimising off and on page, backlinking etc. i woke up one morning, checked my pr and it was gone. also my traffic was hit by the loss. my traffic figures were down 11% so pr MUST generate traffic. i still have a pr of 0, but i really dont know why it suddenly changed.
