wow thats nice..as sachin asked..are you into the new referrals 2.0? also i dont think theres any chance of google banning your account coz of referrals...
you cant' see which are high paying referrals per se..i mean you cant see their conversion rates or can you?? you can know coz you had that referral on that page etc...so how'd you do that?
oh ok..i didnt know that..perhaps my adsense referrals is still old..not 2.0.. dunno..will have to check..
