I have a large account with numerouscampaigns and adgroups. I want to include negative keywords for majority of my words, but cant seem to do it at the campaign level. What is the easiest way to include mass negative keywords (all keywords in a given adgroup would have the same negative keywords)?
You can include negative keywords at the campaign level. In the campaign tab you can see the option "Bulk Edit". Click on it you can find campaig setting in that you can add negative keywords at campaign level.
