I've just signed up and created an 'order'. Seems pretty straightforward. The only thing I don't understand is the excluded word feature. The excluded words, maximum 100 chars, are associated with a keyword. Then it says there's a max 1000 char limit for the ad. So does this mean all the excluded words are applied to each keyword.??? Don't see why it's not like google where a negative word is just another kind of keyword applied to an ad or campaign.
