Step 8: Set default bid. Amazon gives you an opportunity to set different bids by target groups. If you are setting campaign in a account for first time, it does not have any CPC history you can look at the suggested bid for clues what is the bid range in your category. For the close match you can use the suggested bid, but for the rest set the bids at least 20% - 30% lower than the close match.
Step 9: Adding negative kw targeting is optional. There are some cases where you should put negative kw preemptively. For example if you are selling vitamins you would like to add negative terms like "dog", "cat", "pets" so the campaigns does not pickup wasteful traffic. In other case you might put your brand name as a negative term.
Step 10: In this step you have a chance to be creative and add custom text to the ad.
