In ASP or ASP.net, how do I work out if the REFERRER URL from Google was a Sponsored Listings link (i.e. a link from a PPC) or from Googles Natural Listings? Not sure what format or strings to look out for. Likewise form Yahoo if anyone knows ps. I am not after the ASP Code neccessarily, but more which parameters or searc strings to look for.
I think the easiest way is to have a different landing page for the PPC ads, or at least include a querystring in your PPC url and track that in your page.
I'm sure there is a better way rather than including a querystring in the PPC URL. I'm sure Google uses a different URL format for Adwords, but I cannot work out what it is. Any ideas anywone?
