Welcome to the Q&A Forum

So I just read your blog on quality score and after reading the negative keyword section I'm a little confused and I need clarification. In that paragraph you mentioned about not overlapping your negative keywords with your active keywords and you used an example of dog food and dog bed. So my question is, if you put the word dog bed into the negative keyword list isn't the word dog the over lap word? Would you ad not show because the word dog is in the active keyword list?
