Please if anyone could help me with this. Let's say I have a page: mysite.com/mypost and if I leave a backlink to this page on a High PR site in the following format: mysite.com/mypost?referer=XY (?referer=XY thing is just for my stats script) will the page mysite.com/mypost itself get the proper PR boost? Is URL with prefix mysite.com/mypost?referer=XY the same as URL mysite.com/mypost in eyes of Google? The purpose of it is just I want to keep track of stats from the links of this format only. Please any suggestions are welcome. Thank you!
