Recently it was announced that YouTube advertisers are now able to choose specific videos and video channels they don't want their advertisement to appear in. This control and flexibility over YouTube campaigns is a very valuable tool for advertisers as they are able to choose the relevancy of videos that will show their ad. As well as help ensure their target audience will see it. For example, let's say you run a store selling organic fruit and vegetables. You want to stay within the company image and values on maintaining a healthy lifestyle. While your ad is targeted to those living a healthy lifestyle, chances are Jamie Oliver's new chocolate fudge cake recipe may not best fit with our ad and your brand. So you may exclude this video from showing your ad. Handy tool isn't it?
