Plenty of sellers skip automatic campaigns because they want control from day one. That instinct costs them the single best source of keyword data Amazon gives away.
I have launched hundreds of accounts since 2015, and almost every one starts with an auto campaign. Letting Amazon match your ad to real shopper searches tells you which keywords actually convert, which is the foundation your profitable manual campaigns are built on.
The guide below explains what auto campaigns are, why they earn their place in every account, and how to run them so they discover winners instead of quietly wasting spend.
TL;DR — the short version
Amazon PPC auto campaigns let Amazon choose which searches and product pages show your ad, based on your listing. You should use them because they discover converting keywords you would never guess, widen your reach across Amazon, and take minutes to launch. Run them with negative keywords to control waste, harvest the winning search terms into manual exact-match campaigns, and keep them going as an always-on discovery engine.
What Amazon Auto Campaigns Are
An automatic campaign is a Sponsored Products campaign where Amazon selects the keywords and product pages your ad appears on, using your listing content to decide relevance. You do not supply a keyword list, which is what makes auto campaigns the fastest way to get an ad live.
According to Amazon Ads, automatic targeting matches your ad to shopper queries and product pages through several default strategies, so your ad becomes eligible across search results and detail pages the moment the campaign starts. That speed and reach are why our step-by-step Amazon PPC guide recommends starting here.
The trade-off is control. Amazon decides where you show, so an auto campaign without guardrails can spend on searches that never convert, which is why the rest of this guide matters.
Understand the Four Targeting Groups
An auto campaign is not one setting, it splits into four targeting groups, and you can set a separate bid for each. Knowing what they do lets you steer spend toward the ones that convert.
- ●Close match: your ad shows for searches closely related to your product, usually the highest-intent group.
- ●Loose match: your ad shows for broader, looser searches, good for discovery but lower intent.
- ●Substitutes: your ad appears on detail pages for products a shopper could buy instead of yours.
- ●Complements: your ad appears on detail pages for products that pair with yours.
Bid these groups separately rather than as one block. Close match usually earns a higher bid because it converts best, while loose match and complements often need a lower bid or a close eye until the data proves them.
Why Auto Campaigns Are Worth Running
The case for auto campaigns comes down to three things they do better than any manual setup.
- ●They discover keywords you would never guess. Amazon surfaces the real phrases shoppers use, including long-tail terms no keyword tool would hand you.
- ●They widen your reach. Your ad becomes eligible across search results and product pages at once, which puts a new listing in front of more shoppers fast.
- ●They launch in minutes. With no keyword research required to start, an auto campaign gets a product advertising the same day, gathering data while you plan the rest.
None of that replaces manual campaigns, and the real value shows up when you feed what auto campaigns learn into tightly controlled manual ones.
Harvest Keywords for Your Manual Campaigns
Harvesting is the reason auto campaigns pay for themselves. Your search-term report shows every real query that triggered your ad, along with the clicks, spend, and sales each one produced.
The workflow is simple. Read the report every week or two, find the search terms that converted profitably, and move them into a manual exact-match campaign where you control the bid. Strong keyword research for Amazon ads starts here, with Amazon’s own data rather than a guess.
Once a term is winning in your manual campaign, add it as a negative in the auto campaign so the two do not overlap. That keeps the auto campaign hunting for new terms instead of re-buying ones you already scaled.
Set the Right Bids for Auto Campaigns
Bidding is where auto campaigns either stay efficient or leak money. Start each targeting group within Amazon’s suggested range, then follow Amazon’s best-practice guidance and adjust based on which group converts.
Amazon offers three bidding strategies, and the choice matters. Dynamic bids down-only, which lowers your bid when a click is unlikely to convert, is the safe default for a steady auto campaign. Dynamic bids up-and-down suits a launch when you want aggressive visibility and can afford to spend on data, while fixed bids are mainly for testing.
Match the strategy to the goal. A profit-focused campaign leans on down-only to protect margin, and a launch campaign accepts up-and-down to buy the velocity that builds rank.
Control Wasted Spend With Negative Keywords
Auto campaigns need guardrails, because Amazon now matches on meaning as well as exact words, so your ad can appear on loosely related searches. Without negatives, that reach becomes waste.
Read the search-term report for queries with clicks and no sales, or terms that clearly do not fit your product, and add them as negative keywords. Our walkthrough on how to find negative keywords with low click or sales data shows exactly what to cut.
Do this every week and the auto campaign gets sharper over time, spending more of its budget on searches that actually convert.
Auto vs Manual Campaigns, When to Use Each
Auto and manual campaigns are partners rather than rivals, and most accounts run both. Auto campaigns handle discovery, surfacing new terms and testing broad relevance. Manual campaigns handle precision, scaling the proven winners at a bid you control.
The clean structure is to let auto find, then let manual scale. Feed the winning search terms from auto into manual exact-match campaigns, keep auto running to keep discovering, and read what a good ACoS looks like to judge each one against your margin. Our guide to structuring PPC campaigns lays the whole framework out.
Set Up an Auto Campaign
Getting an auto campaign live takes a few minutes in campaign manager.
Step 1: Create the Campaign
Start a new Sponsored Products campaign and choose automatic targeting. Amazon handles the keyword and product matching from your listing, so there is nothing to research before you launch.
Step 2: Add Your Product and Budget
Add the product you want to advertise and set a daily budget, the maximum the campaign can spend in a day. Give it enough to gather real data, since a starved budget produces too few clicks to learn from.
Step 3: Set Bids and Bidding Strategy
Set a starting bid, choose dynamic bids down-only for a steady campaign, and set separate bids by targeting group if you already know which ones matter. Then let it run for a week or two before you judge it.

Conclusion
Auto campaigns are the discovery engine of a healthy Amazon account. They surface the converting keywords you would never guess, widen your reach fast, and launch in minutes, all for a few dollars of test spend.
Run them with negatives to control waste, harvest the winners into manual exact-match campaigns, and keep them going so the discovery never stops. Used this way, an auto campaign is not a lazy shortcut, it is the first move in a profit-focused strategy.
