Communicating with AdWords about the particular searches you want your ads to match with can be complex, and if you get it wrong you can end up with a lot of wasted clicks and money with no leads!

Negative keywords is one of a series of Keyword Matching Options AdWords provides to specifically identify your desired searches. These can be applied in a Boolean style to ensure  AdWords knows exactly which searches you want to target. Negative keywords can also be applied to individual AdGroups or across an entire Campaign
