I'm quite news to Adsense and have had one campaign running for a few months. I have started another website, comletely different to the first, not at all related. Do I have to ad a new "campaign", "Adgroup" or whole new Adsense account? Thanks.
Woops, yep I meant Adwords. Looks like I'll have to create a new account as I have a redemption voucher, but only one can be used per account. Thanks for the reply though.
