There are lots of metrics to consider when it comes to Amazon PPC Advertising. Here's a quick reference list to get you started:

  • Spend: The amount of money spent on clicks on your ads during the time frame selected

  • Sales: The product sales from orders within 14 days of a click on an ad if that click was made during the time frame selected. 

  • ACoS (Advertising Cost of Sales): Spend divided by Sales. You can look at this as how much you have to spend on ads per sale.

  • Impressions: The number of times Amazon shoppers saw your ad during the time frame selected, whether they clicked or not.

  • Clicks: How many times users clicked on your ads during the time frame selected

  • CTR (Click Through Rate): The number of clicks divided by the number of impressions.
