Is there anyway to trick the referrer into being a site of your choice? So if you have an iframe on site.com, then you can change site.com to whatever you want? Thanks
Yes this can be done, although it is not good SEO practice and G may punish you if you are found out. Why did you wish to do it, there may be a less damaging way to achieve the same results.
G called it "sneaky redirection". if you redirect from your own site then it is ok. But ranking will be a bit down.
