Automatic vs Manual Campaigns on Amazon PPC (2026 Guide)

Marcus launched his first Sponsored Products campaign on Amazon two years ago. He picked automatic targeting because it seemed easier. Within 60 days, he had spent $4,200 on ads and generated $11,000 in sales. Not bad at 38% ACoS. But when he finally pulled his search term report, he found a problem: 40% of his ad spend had gone to completely irrelevant search terms. Keywords like "free sample" and "wholesale bulk" were eating budget without a single conversion.

So he switched everything to manual campaigns. His ACoS dropped to 22%. But his total sales dropped too. The manual campaigns only targeted the keywords he already knew about. He lost all the new keyword discovery that auto campaigns had been quietly delivering.

The right answer was never auto or manual. It was both.

Many sellers treat automatic vs manual campaigns in Amazon PPC as an either-or decision. Each targeting type serves a specific purpose: auto campaigns discover, manual campaigns optimize. Run them together with a clear workflow and you spend less and sell more. This guide shows how, step by step.

Updated October 16, 2026. Now with a side-by-side comparison table, how to bid the four auto targeting groups separately, keyword vs product targeting, Amazon's own timelines and thresholds, its Target Promotion tool, a worked harvesting example, budget splits by product stage and an expanded FAQ.

Automatic vs Manual Campaigns on Amazon: Side-by-Side Comparison

Every Sponsored Products campaign gets one targeting type when you create it: automatic or manual. You cannot switch it later. As Amazon's targeting guide puts it, "Once the campaign is live, you will not be able to change the campaign targeting." Here is how the two compare:

Amazon does not frame it as a choice either. Its targeting guide says automatic targeting "is a great supplement to manual campaigns, and advertisers often find success running both."

How Amazon Automatic Campaigns Work

When you create an automatic targeting campaign, Amazon decides which search terms and product pages trigger your ads, based on what it knows about your product. You set a daily budget and a bid. You cannot add keywords or product targets yourself, only negative keywords and negative products to block traffic you do not want. That is one reason a clear, keyword-rich listing matters: the better Amazon understands your product, the more relevant its matches tend to be.

The Four Auto Targeting Groups: Close Match, Loose Match, Substitutes and Complements

Every automatic campaign runs on four targeting groups. Two match shopper searches, and two match product detail pages. Here are Amazon's definitions, with a stainless steel water bottle as the example product:

Amazon's own example in its Sponsored Products targeting guide uses an espresso maker: close match can show it for "stainless steel espresso machine," loose match for "coffee machine." The "common pattern" column is a rule of thumb, not a law. Plenty of products get their best orders from substitutes, which is exactly why each group needs its own bid.

How to Bid Each Auto Targeting Group Separately

Amazon lets you "set a single 'default bid' in your automatic campaign, or set bids by targeting group." Use the second option. A single default bid pays the same for a loose-match click as for a close-match click, even though the two rarely perform alike. You can also switch an individual targeting group off in the ad group's targeting settings.

A sensible starting point:

• Close match: Your highest auto bid
• Loose match: 30–50% lower than close match
• Substitutes: Same as close match or slightly lower
• Complements: Your lowest bid

After about two weeks, compare each group's spend, orders and ACoS on the auto ad group's targeting tab. Raise the bid on a group running well below your target ACoS, lower it on a group running above, and switch a group off only after it has spent meaningfully with no orders. For the bidding strategy, Amazon recommends dynamic bids up and down for automatic campaigns and suggests down only if you optimize for return on ad spend. If profit matters more to you than reach, down only is the safer start.

The Strengths of Auto Campaigns

Auto campaigns excel at keyword discovery. Amazon sees shopper behavior you cannot, and an auto campaign will surface keywords you never would have found through manual research. It also finds product pages: its search term report lists the ASINs where your ad got clicks and orders, a ready-made list of competitor products to target later. And it takes minutes to launch: no keyword lists, no match type decisions, no bid-per-keyword calculations.

Jennifer runs a kitchenware brand with 25 products. She launches an auto campaign for every new product on day one. Within two weeks, each auto campaign reveals 15-30 converting search terms she adds to her manual campaigns. Without that discovery phase, she estimates she would miss 30% of her profitable keywords.

The Weaknesses of Auto Campaigns

The trade-off is control. You cannot choose which keywords trigger your ads or set different bids for different search terms, and Amazon keeps spending on irrelevant traffic until you add negatives. That is why auto campaigns typically run at a higher ACoS than well-optimized manual campaigns: Amazon is spending your money to learn what works. And because the targeting type is fixed at launch, you cannot turn a well-trained auto campaign into a manual one; you build a new manual campaign from its data.

How Amazon Manual Campaigns Work

Manual campaigns put you in control. You choose what to target and set a bid for each target. There are two kinds of manual targeting, keywords and products, and Amazon recommends that you "avoid mixing different targeting strategies within the same campaign and ad group." Keep keyword targets and product targets in separate campaigns so each has its own budget and report.

Manual Keyword Targeting: Broad, Phrase and Exact Match

Keyword targeting shows your ad when a shopper's search matches a keyword you chose. Three match types give you three levels of precision:

• Broad Match: Your ad shows for search terms that contain your keyword's words in any order, plus related variations. Bidding on "stainless water bottle" could trigger "best water bottle stainless steel" or "insulated stainless bottle for kids."
• Phrase Match: Your ad shows when the search term contains your keyword phrase in the same order, with words before or after. "Stainless water bottle" triggers "large stainless water bottle" but not "water stainless bottle."
• Exact Match: Your ad shows only when the search term matches your keyword word for word, or with very close variations. Maximum precision, maximum control.

Amazon's guidance for the same keyword across match types is to set the highest bid on exact, a lower one on phrase and the lowest on broad, and to test match types for at least one to two weeks before pausing keywords. Our match types guide covers when to use each.

Manual Product Targeting: ASINs and Categories

Product targeting shows your ad to shoppers looking at specific products or browsing a category. Amazon lets you target "either individual products, or entire categories," and refine category targets by attributes such as brand, price range and ratings. Typical uses:

• Competitor ASINs where your offer is stronger: a better price, a higher rating or a bigger bundle
• Complementary products and your own ASINs, to cross-sell
• Refined categories, for example a category filtered to products priced above yours or rated below yours

The best ASIN list usually comes from your own auto campaign: substitutes and complements traffic appears in its search term report as ASINs, with clicks and orders attached. Our product and category targeting guide walks through the setup.

The Strengths of Manual Campaigns

Manual campaigns deliver precision and efficiency. You decide exactly where your ad spend goes. You can bid aggressively on high-converting keywords and pull back on everything else, so your proven exact match terms can run well below the ACoS of your auto campaign.

David sells premium leather wallets on Amazon. His manual exact match campaigns consistently run at 14% ACoS. His top five keywords account for 60% of his PPC sales. None of that would be possible in an auto campaign where Amazon distributes budget across dozens of search terms without his input.

The Weaknesses of Manual Campaigns

Manual campaigns only target what you tell them to target. If a trending search term emerges next month that is perfect for your product, your exact match campaign will miss it unless you find and add it. They also need ongoing management: bids to adjust, keywords to add, underperformers to pause. A manual campaign left alone for 60 days slowly degrades as the market shifts around it.

When to Use Automatic vs Manual Campaigns

The right mix depends on what you already know about the product:

For launches, our product launch PPC strategy covers bids, budgets and how long to accept a higher ACoS.

The Auto-to-Manual Workflow: Harvesting Search Terms Step by Step

This is the loop that ties the two campaign types together. Amazon calls it target harvesting: moving targets from broad automatic targeting to more focused manual targeting.

Step 1: Launch an Automatic Campaign for Discovery

For every new product, start with an automatic campaign. If you have only a few products, Amazon recommends one ASIN per campaign, which keeps each product's search term data clean. Set bids by targeting group as described above.

Size the budget by clicks, not by feel. Amazon suggests judging a keyword after at least 20 clicks, so you want enough clicks for your main search terms to reach that within two weeks. At the 2026 average Sponsored Products CPC of $1.22 reported by Ad Badger (data from its users, January–August 2026), $25 a day buys about 20 clicks. A simple rule of thumb: daily budget = your category's average CPC × 20–40 clicks.

Step 2: Let It Run About Two Weeks

"We recommend that you let your automatic campaign run for about two weeks before creating a manual campaign," says Amazon. In the meantime, only block obvious mismatches, such as the wrong product type or material. Ad-attributed sales can arrive days after the click, so the most recent days always look worse than they will end up.

Step 3: Mine Your Search Term Report

Pull the search term report for the auto campaign and sort what you find into four groups:

• Winners: 2–3+ orders at or below your target ACoS. Move them to manual exact match campaigns.
• Maybes: one order, or ACoS a little above target. Leave them in auto and check again next week.
• Losers: 20+ clicks and zero orders. Add them as negative exact in the auto campaign, and use negative phrase for concepts that never fit (for example "plastic" for a stainless steel bottle). Amazon recommends phrase or exact match for negatives.
• ASINs: product pages that brought orders go into a product targeting campaign; ASINs with many clicks and no orders become negative product targets.

Why 20 clicks? At the 2026 average conversion rate of 11.1% (Ad Badger), 20 clicks would normally bring about two orders, so zero orders after 20 clicks is a real signal. Zero orders after five clicks is not. Our search term report guide shows where to find the report and how to read it, and the negative keywords guide covers negation in depth.

Repeat this search term harvesting every week. It is one of the highest-impact routine tasks in Amazon PPC.

Step 4: Use Target Promotion to Speed Up Harvesting

Since July 25, 2024, Amazon's console has a built-in helper for this step. Target Promotion, found on the "Search term ad groups" page, suggests search terms and targets to promote from automatic to manual campaigns at scale, and it is also available through the Amazon Ads API. You still review and apply the suggestions. Check each one against your target ACoS before promoting it, and make sure the promoted term is negated in the auto campaign, since negatives are still added by hand or with a tool.

Step 5: Build Manual Campaigns Around Proven Keywords

Take the winners from Step 3 and create manual campaigns organized by match type and targeting type:

• Exact match campaign: Your proven winners. Bid most aggressively here. These keywords have already shown they convert.
• Broad or phrase match campaign: Your expansion layer. Run your winners in broad or phrase match to find related variations you may have missed.
• Product targeting campaign: The ASINs that converted in auto.

Set your manual campaign bids using the max bid formula: Product Price × Target ACoS × Conversion Rate. Adjust up or down based on placement performance. If you don't have a target ACoS yet, our free Amazon ACoS calculator works out your break-even and target ACoS from your price and costs.

Step 6: Negate Harvested Terms in the Auto Campaign

This step is critical and many sellers skip it. When you move a keyword from auto to manual, add it as a negative exact match in the auto campaign. Sellers and tool makers disagree on how Amazon handles two of your own campaigns targeting the same search, but the practical cost is clear either way: the auto campaign can keep serving the term at its own bid, the term's data is split across two campaigns, and you lose the bid control you built the exact campaign for.

Your auto campaign should only spend on search terms you have not yet moved to manual. Our keyword harvesting guide covers promotion thresholds, starting bids and negation in detail.

Step 7: Keep Auto Running at a Lower Budget

Do not turn off your auto campaigns once manual is live. Reduce the daily budget and let them run: seasonal keywords, trending products and shifting shopper language keep creating search terms that a manual-only setup will miss. Think of auto as a research assistant on a small budget. After each round of changes, give negatives time to work: Amazon suggests letting them run for two weeks or more before changing your strategy again.

Worked Example: Harvesting a Two-Week Auto Campaign

Take a $30 stainless steel water bottle with a 25% target ACoS. After two weeks, the auto campaign's search term report shows these terms (simplified):

The bids come from the max bid formula: $30 × 25% × the term's conversion rate. "Insulated water bottle 32 oz" converted 14 of 120 clicks (11.7%), so its exact bid is $30 × 0.25 × 0.117 = $0.88, below the $0.95 it averaged in auto. "Stainless steel water bottle" (13.3%) gets $1.00 instead of $1.10. "Metal water bottle for kids" was running below target at $0.85 a click; its bid can rise to $0.94 to buy more traffic.

The two negatives alone remove $42.30 of spend that brought no orders, which takes the remaining terms from 32.3% to 28.0% ACoS. The exact bids then aim each winner at the 25% target. The competitor ASIN and the one-word generic term stay in auto until they have enough data. One caveat: conversion rates from 40–120 clicks are estimates, so check the new bids again after another two weeks.

How to Split Budget Between Auto and Manual Campaigns

No single ratio fits every product. The split should follow the product's stage. A practical starting point, as a rule of thumb rather than an Amazon rule:

For mature products, a useful reference point: in expert advice published on Amazon Ads' site, AMZ Pathfinder, an Amazon Ads Verified Partner, writes that experimentation "should take up no more than 10–15% of your budget." Move budget in steps as winners graduate to manual, not all at once. Our PPC budget strategy guide covers the rest.

Automatic Campaigns vs Automated PPC: Not the Same Thing

Searches like "manual PPC or automated PPC" often mix two different things. An automatic campaign is a targeting type: Amazon chooses where the ad shows. Automated PPC means software or rules that change bids, budgets, keywords and negatives for you, and it works on automatic and manual campaigns alike.

Amazon's console already automates part of the routine for free: dynamic bidding, schedule-based bid rules (since November 2023), budget rules and Target Promotion suggestions. Negatives are still added by hand or with a tool, and someone has to run the weekly harvesting loop. Third-party tools range from rules you write yourself to full autopilot. Daniks.AI, for example, creates its own campaigns and runs bids, budgets, keyword harvesting and negatives 24/7 against the target ACoS you set, without touching the campaigns you already run. Our Amazon PPC automation guide compares the options.

Common Mistakes With Auto and Manual Campaigns

Running only auto campaigns forever. Some sellers launch auto, see sales, and never build manual campaigns. Their best keywords stay at auto-campaign bids, with no keyword-level control and no way to push them harder. Auto is a starting point, not a long-term strategy.

Switching to manual too early. Killing your auto campaign after one week of data means you are building manual campaigns on insufficient information. Amazon recommends about two weeks; slow-selling products may need longer before key terms reach 20 clicks.

One default bid for all four auto targeting groups. Loose match and complements then get the same price as close match. Bid each group separately and review them one by one.

Not negating across campaigns. Running the same keyword in both auto and manual without a negative in auto means you lose control of which campaign serves the term and at what bid.

Setting and forgetting. Both campaign types need weekly attention. Auto needs negative keywords added. Manual needs bids adjusted and new keywords added. A structured campaign management routine is the difference between campaigns that improve over time and campaigns that slowly decay.

Using the same bids for all match types. Exact match is the most targeted and usually converts best, and Amazon's own guidance is to bid highest on exact, lower on phrase and lowest on broad. A common starting ratio is phrase at 80–90% and broad at 60–70% of your exact bid.

Frequently Asked Questions

Is automatic or manual targeting better on Amazon?

Neither on its own. Automatic campaigns are better for discovery and need no data to start; manual campaigns are better for control and usually reach a lower ACoS on proven keywords. Amazon itself notes that advertisers often find success running both, and most well-run accounts use auto to find search terms and manual to scale them.

How long should an auto campaign run before I create a manual campaign?

About two weeks, which is Amazon's own recommendation. Use the data, not the calendar, as the final check: a search term needs roughly 20 clicks before you can judge it, so slow-selling products may need longer.

Can I change an automatic campaign to manual?

No. Amazon does not let you change a campaign's targeting type once it is live. Create a new manual campaign, add the converting search terms from your auto campaign's search term report, and negate those terms in the auto campaign.

Can I run auto and manual campaigns for the same product at the same time?

Yes, and you should. Auto keeps discovering while manual scales your proven winners. Just add each search term you move to manual as a negative exact in the auto campaign.

Should I turn off my auto campaign once manual campaigns are running?

Usually not. Lower its budget instead, so it keeps finding new search terms and ASINs. Consider pausing it only if it has stopped producing new converting terms for several weeks and its ACoS stays well above your target.

What is a good ACoS for auto campaigns?

There is no single number. Amazon itself says there isn't a definitive good ACoS, only that yours needs to be lower than your profit margin. Auto campaigns usually run several points higher than exact match campaigns for the same product, and that is acceptable as long as the auto campaign stays below break-even and keeps producing keywords for your manual campaigns.

The Bottom Line

Auto and manual campaigns in Amazon PPC are not competing strategies. Auto campaigns discover what works. Manual campaigns optimize what you have discovered. The sellers who get the best results run both: start with auto and bid its four targeting groups separately, build manual campaigns around proven keywords after about two weeks, keep auto running at a reduced budget, negate across campaigns, and repeat every week.

Your ad spend is too valuable to guess. Build the system, follow the process, and let the data tell you where every dollar should go.
