I could imagine the Header title, other Meta-Tags & content...
...BUT there are so much sites with the same Tags maybe
even the same number of visitors.
PageRank HAS something to do with ranking
at least as ONE of lots of factors. How could you be so sure
Google doesn't even tell people how they rank their sites and
wouldn't it be stupid to create something like PR without sense?
Even if PR is just there for back-links...
...aren't back-links good for the ranking too?
Why else would people try to get more links?
To get a higher PR which isn't important at all??
Sounds strange to me.
So what volun wants to say is that this blackhat backlink-building tool is good for NOTHING?
Maybe to pose arround with "I got PR8!!" buuut who would actually do that besides 12 year olds... o_0
