Below is a list of keyword terms that the vast majority of advertisers should add to their PPC accounts as negative keywords at the campaign level. Negative keywords stop your ad from showing up on particular searches. For instance, if you fix major appliances in the Boston area, and want to advertise on the term Refrigerator repair in Boston, you would not want to be found when someone searches for Refrigerator repair jobs in Boston. That’s most likely a person searching for a job. To stop your ad from showing on that term, you can ad jobs as a negative keyword match.
