pr 6 teahost.com - I didn't even pay attention, it worked out by itself... no link submissions whatsoever...but that was long ago, now domain is for sale
There are alot of PR5 and PR6 domains that do a lot more traffic than several PR7 and PR8 sites I have seen - PR isnt everything TRAFFIC IS EVERYTHING
Well if you are part of Algolo your answer should be atleast PR6. When you join up you own part of the company!
but i guess PR helps you appear more frequent in search engines when you can't optimize your website for certain keywords, like forums or article sites for example. is that right?
Yes, since PR checking (and PR tricks) has been made so easy I think they have left it just to have webmaster talk about it. They are now using better algos that are less influenced by PR links. What now matters much more is QUALITY links, links from pages that have good contents and contents that are related to the subject. I have been requested a SEO consultancy by a guy that has a PR4 site for a quite small niche (italian-ukrainan commerce & relationships). Despite his PR4, his site is ranking EXTREMELY low, and he wanted me to help with that. By examining the backlinks I found a LOT of them (over 1.000) and at least three PR5 guestbooks that linked to him (one on a site about american birds, one on a site about a rock group and another about humor, in french). It turned out he had gone around doing a real link spamming campaign, and harmed his site beyond repair. All those unqualified links gave him a strong PR but destroyed his ranking!
