I’ve been throwing a lot of keywords in my campaigns (thousands), most of which are misspellings and alterations for my main keywords. My account came up with a notice that I can’t put any more keywords in – I’m maxed out.

Can I create a new account with a different e-mail address but the same credit card? Does anyone know the limit of Goggle accounts one person/business can have. I’m sure you could get in trouble if you had the same keywords promoting the same services in different accounts. Anybody know Goggle’s policy on creating multiple accounts? I can’t find it on their site.

As far as I know, there isn't a policy against multiple Adwords accounts, but I would email Google just to be sure. Just tell them you've run out of keywords, and they'll get you know what to do. (Maybe there's some way they can expand your current account to allow for more keywords...)
