How to use negative keywords?

[fischermx]

Hi,

I have a bunch of keywords like :
blue widgets
orange widgets
purple widgets

But I dont want my site to show up for "red widgets" at all.
Should I enter :
blue widgets -[red widgets]
orange widgets -[red widgets]
purple widgets -[red widgets]

or

blue widgets
orange widgets
purple widgets
-[red widgets]

Which of both?

Another related question, are the negative keywords considered also for content ads? or just for search ads?

Sorry, could somebody move this to adwords forum?
thanks.
