We’ll first learn terms you’ll come across while setting up the Ads


The highest level in the hierarchy of Amazon Ads, campaigns are where you will set the details for your PPC campaigns - the organization of the Ads and the targeting.

Campaigns are of two types - Automatic Campaigns and Manual Campaigns.

Automatic Campaigns

Amazon will automatically choose the keywords for you to target based on your product listing information such as the title, bullet points, description, and keyword search terms. You will still control the bid price and daily budget but all of the keywords will be chosen by Amazon.

Manual Campaigns

With manual campaigns, the seller chooses the keywords to be targeted in the ads. There are a couple of options on how to target these keywords - which are called the Match Types on Amazon.

The match types map the instances for on which the ad is shown providing you the capability to restrict ads only for the best buyer audience.

Keyword Match

Other than specifying the keywords for the campaign, Amazon also lets you match the different types of searches. You can decide to display your product ad based on the matches of the search term with your keywords for exact search term match, terms are padded before and after the search terms, make restrictions on the order in which the search terms are displayed, etc.

Keyword Bids

The keyword bids are the maximum cost you are willing to pay when someone clicks your ad. Manual Campaigns require you to bid separately per keyword, while on automatic campaigns you specify the default bid. The default bid is the maximum cost-per-click for every ad from this ad group.

Post creating an ad, you’ll see quite a number of data points associated with each ad instance, those terms are explained below,


The number of times your product ad was displayed, for a search query that matched the keywords you are running ads for. Sellers only pay for ads only when a customer clicks on your ad not for the number of impressions or for running the ads.


The number of times shoppers clicked on your product ad to view the complete product detail page.

CTR - Click Through Rate

Expanded as Click through Rate, is the ratio of the Impressions versus the clicks, ie the number of times your advertisement was clicked by a shopper, for each time your ad was displayed.

Average Cost per Click

The average amount you’ve been charged for your Amazon product ad. Average cost-per-click (Avg. CPC) is calculated by dividing the total cost of your clicks by the total number of clicks.

The average amount that you’ve been charged for a click on your ad. Your average CPC is based on your actual keyword bid / maximum cost per click. The average CPC might be different than your maximum cost-per-click (max. CPC), which is the highest amount that you’re willing to pay for a click.

Here’s an example of how Amazon calculates your average CPC.

Let's say a keyword is bid at $1, and the ad gets two clicks, one costing $0.20 the other costing $0.40.

The Total Cost per Click is $0.60.Divide $0.60 (the total cost) by 2 (your total number of clicks) to get an average CPC of $0.30.
