Interesting topic
( but not as popular as "Oracle Porn is drunkkkkk" )
I've always read that to make the most of PPC SE's listings, insted of linking directly to sponsors, you should create custom pages, with a few options for the surfer.
If this applies to PPC SE's, then i wonder why not to regular SE listings.
I've also heard that with unexperienced surfers ( and those coming from SE's are less experienced than TGP surfers )
no content sites ( "fake" or real review sites, or simpe hubs ) do great. I thought that some of them may bookmark it, since they don't know yet where to find the free porn.
