Plain-language reference

Amazon PPC, in plain words.

The terms new sellers run into most, each explained in a sentence or two. No jargon to decode the jargon.

ACOS (Advertising Cost of Sales)
Ad spend divided by the sales your ads brought in, shown as a percentage. A lower number means each ad dollar is earning more. What counts as acceptable depends on your profit margin.
Ad group
A folder inside a campaign that holds related ads and the keywords or products they target.
Ad spend
The total Amazon charges you for clicks on your ads.
Auto campaign
A campaign where Amazon chooses which searches and products to show your ad against, based on your listing.
Bid
The most you are willing to pay for one click on your ad.
Broad match
Your ad can show when a shopper’s search includes all the words of your keyword, in any order, along with close variations.
Budget
The amount you allow a campaign to spend each day.
Campaign
The top-level container for your ads. It holds the budget, the settings, and one or more ad groups.
Click-through rate (CTR)
Clicks divided by impressions. It shows how often people who saw your ad chose to click it.
Conversion rate (CVR)
Orders divided by clicks. It shows how often a click turns into a purchase.
Cost per click (CPC)
What you actually pay for a click. It can be lower than your bid.
Exact match
Your ad shows only for the exact search term, or a very close variation of it.
Impression
One time your ad is shown to a shopper.
Keyword
A word or phrase you give Amazon to match against what shoppers type into the search bar.
Manual campaign
A campaign where you choose the keywords or products to target yourself.
Negative keyword
A word or phrase you tell Amazon not to show your ad for. It stops spend on searches that do not fit.
Organic ranking
Where your listing appears in search results without paid ads.
Phrase match
Your ad can show when a search contains your keyword’s words in the same order, with other words allowed before or after.
Placement
Where on Amazon your ad appears, such as the top of the search results or on a product page.
Product targeting
Aiming an ad at specific products or categories instead of keywords.
ROAS (Return on Ad Spend)
Sales from your ads divided by ad spend. It is the same information as ACOS, turned upside down.
Search term
The actual words a shopper typed. It may differ from the keyword you chose.
Search term report
A report listing the search terms that triggered your ads and what happened after each one.
TACOS (Total Advertising Cost of Sales)
Ad spend divided by your total sales, both ad-driven and organic. It shows how much of your overall revenue goes to advertising.

Amazon renames features and changes settings from time to time. If a screen in Seller Central looks different from what is described here, the idea behind the term still holds.
