What’s the difference between automatic and manual campaigns?

Co-Founder at Amersify

Introduction

One of the first choices you’ll make when setting up Amazon ads is between Automatic and Manual targeting, and it remains one of the most important strategic decisions in 2025.

Automatic campaigns let Amazon decide who sees your ads, while Manual campaigns give you full control. Both can deliver success — but only when used together in a structured system.

This article explains how each campaign type works, when to use them, and how leading brands combine both for maximum profitability and data clarity.

1. What Are Automatic Campaigns?

Automatic campaigns allow Amazon’s algorithm to match your ads to relevant shopper searches and product detail pages automatically — no keyword creation required.

How It Works:

Amazon analyses your listing content (titles, bullet points, backend terms, and A+ content).
It automatically places your ads on relevant search terms and product pages.
You pay only when a shopper clicks your ad.

Benefits:

Simple setup — ideal for beginners or new ASIN launches.
Excellent for discovering keywords that drive conversions.
Adjusts automatically to search trend shifts.

Limitations:

Less control over targeting and bid allocation.
Can generate wasted spend if listings are poorly optimised.

Tip:

Automatic campaigns are your data engines. Use them to gather high-performing search terms, then transition those into Manual campaigns for precision and scalability.

2. What Are Manual Campaigns?

Manual campaigns give you full control over where your ads appear. You select the keywords, ASINs, and bids that drive targeting decisions.

How It Works:

Add keywords or ASINs manually.
Assign individual bids for each target.
Choose match types (Broad, Phrase, or Exact) to adjust targeting precision.

Benefits:

Greater control over spend efficiency and targeting accuracy.
Scalable and predictable performance when optimised.
Enables fine-tuned control for profitability.

Limitations:

Requires consistent data review and bid management.
Can underperform without a foundation of search term data.

Insight:

Manual campaigns are the refinement layer of your optimisation funnel — informed by the data your Automatic campaigns generate.

3. Match Types Explained (Manual Campaigns)

Match Type	How It Works	Example
Broad	Shows ads for searches containing your keyword in any order or format.	Keyword: “protein powder” → Search: “best powder for protein shakes”
Phrase	Shows ads when the search includes your keyword sequence in order.	Keyword: “protein powder” → Search: “organic protein powder 1kg”
Exact	Shows ads only for your precise keyword phrase.	Keyword: “protein powder” → Search: “protein powder” only

Tip:

Use Broad for data discovery, Phrase for mid-funnel refinement, and Exact once you’ve identified proven converters.

4. Key Differences Between Automatic and Manual Campaigns

Feature	Automatic Campaigns	Manual Campaigns
Targeting Control	Amazon decides	You decide
Setup Time	Fast	Slower
Keyword Discovery	Excellent	Requires existing data
Management Need	Low	Ongoing monitoring
Budget Efficiency	Moderate	High (with optimisation)
Ideal Use Case	Research and data gathering	Scaling and profitability

Automatic campaigns uncover opportunities — Manual campaigns convert them efficiently.

5. How to Combine Automatic and Manual Campaigns

The most effective advertisers run both campaign types together.

Step 1: Launch an Automatic Campaign

Run for 1–2 weeks to identify converting search terms using the Search Term Report.

Step 2: Build a Manual Campaign

Move your top-performing keywords from the Automatic campaign into a Manual one. Assign targeted bids and match types based on performance intent.

Step 3: Add Cross-Negatives

Add those successful manual keywords as Negative Exact in your Automatic campaign to prevent duplication or internal bidding conflicts.

Tip:

This setup — called Segmented Optimisation — creates a feedback loop. Automatic campaigns feed insights, Manual campaigns refine strategy, and budgets stay tightly aligned with performance.

2025 Update:

Amazon’s Smart Targeting Recommendations tool now supports this process by automatically surfacing high-ROAS search terms from Automatic campaigns and suggesting migration to Manual targeting lists. You can find these recommendations directly within Campaign Manager under the “Performance Insights” tab.

6. How to Allocate Budget

Goal	Recommended Split
New Launches	70% Automatic / 30% Manual
Growth Stage	50% Automatic / 50% Manual
Established Products	20% Automatic / 80% Manual

Maintain some Automatic budget even for mature products. It keeps keyword discovery active and ensures you don’t miss new search trends.

Dynamic Budget Rules (2025 Note):

Advertisers can now use Dynamic Budget Rules to automatically allocate more funds toward high-performing Manual campaigns or reallocate daily spend based on conversion performance, maintaining consistent learning momentum without manual intervention.

Cross-Reference:

7. When to Switch Between Campaign Types

Scenario	Recommended Approach
New ASIN launch	Start with Automatic to gather data.
High wasted spend	Shift toward Manual for tighter control.
Category expansion	Run both to maintain broad visibility.
Mature ASINs	Prioritise Manual campaigns for sustained profit.

Insight:

Monitor TACOS trends when switching campaigns. A declining TACOS with stable or increasing total revenue signals that your Manual shift is improving both efficiency and organic growth.

8. Performance Optimisation with 2025 Tools

In 2025, Amazon has expanded real-time analytics through Amazon Marketing Stream. Use it to track hourly campaign performance, adjust bid pacing, and refine when Automatic versus Manual campaigns should deliver impressions.

Additionally, Performance Forecasting in the ad console allows you to simulate how bidding adjustments in Manual campaigns impact future conversion potential. Together, these tools close the optimisation loop across both campaign types.

FAQs

Do I need Brand Registry to run these campaigns?

No. Both Automatic and Manual campaigns are available to all sellers.

Can I run both campaign types for the same ASIN?

Yes — and you should. Just make sure you implement cross-negatives to avoid internal competition.

How long should I let Automatic campaigns run before switching?

Allow 7–14 days to collect adequate search term data before extracting top performers.

Which is more efficient — Automatic or Manual?

Manual campaigns deliver higher efficiency once optimised. Automatic campaigns excel in keyword discovery and data gathering.

Summary

Automatic and Manual campaigns aren’t rivals — they’re strategic partners. Automatic campaigns gather intelligence, while Manual campaigns refine bids and expand profitability.

Modern Amazon advertising blends both campaign types through data-driven automation, Dynamic Budget Rules, and Smart Targeting Recommendations to reduce guesswork and accelerate results.
