I read in a couple places that regarding adwords inactive keywords that "they are a cancer in your account", so went through last night pausing them all (in my adwords account). I'm wondering how they (inactive keywords) will affect my Yahoo account. Should I pause the inactives hoping to turn some on later? Should I delete them all? Do I need to worry about it? Maybe they don't count against me? Thank you for taking the time to read this.
