## Why Advertise on Amazon

Amazon is the world's largest product search engine. Over 60% of product searches start on Amazon, not Google. When users search on Amazon, they are ready to buy. This purchase intent makes Amazon advertising uniquely valuable.

The real advantage is data. Amazon has first-party purchase data on 300+ million active customers. You can target users based on what they actually bought, not inferred interests. No other platform offers this level of purchase-intent targeting.

### Amazon Ads Advantages

- **Purchase intent:** Users are actively shopping, not browsing or socializing
- **First-party data:** Target based on real purchase history and shopping behavior
- **Closed-loop attribution:** Direct ad-to-purchase measurement without third-party tracking
- **Organic ranking boost:** Sponsored Products sales improve your organic search ranking on Amazon
- **Amazon DSP:** Retarget Amazon shoppers across the open web with programmatic display

## Amazon Ad Types

Amazon offers several ad formats, each serving a different purpose in your advertising strategy:

| Ad Type | Placement | Best For | Requirements |
| --- | --- | --- | --- |
| Sponsored Products | Search results, product pages | Direct sales, product launches | Active product listing |
| Sponsored Brands | Top of search results | Brand awareness, product line | Brand Registry required |
| Sponsored Brands Video | Search results (video) | Product demos, differentiation | Brand Registry + video asset |
| Sponsored Display | Product pages, off-Amazon | Retargeting, competitor conquest | Professional seller account |
| Amazon DSP | Amazon + third-party sites | Full-funnel, audience targeting | Typically $10K+/month spend |

### Sponsored Products

The bread and butter of Amazon advertising. These keyword-targeted ads appear in search results and product detail pages. They look like organic listings with a small "Sponsored" label. Highest volume, most predictable returns.

### Sponsored Brands

Banner ads at the top of search results featuring your brand logo, custom headline, and up to three products. Drive awareness for your brand and direct shoppers to your Brand Store or product collection page.

### Sponsored Display

Retargeting and audience-based display ads that appear on product detail pages, customer review pages, and third-party websites. Target shoppers who viewed your products or similar products from competitors.

### Amazon DSP

Programmatic display and video ads across Amazon properties (IMDb, Twitch, Fire TV, Kindle) and the open web. Leverage Amazon's purchase data for off-Amazon retargeting.

## Amazon Targeting with First-Party Data

Amazon's targeting capabilities are built on first-party purchase and shopping data that no other platform can match:

### Keyword Targeting

Target specific search terms shoppers use on Amazon. Supports exact, phrase, and broad match types. The foundation of Sponsored Products campaigns. Keyword performance data includes clicks, conversions, ACoS, and attributed sales.

### Product Targeting

Target specific ASINs (products) or product categories. Your ads appear on competitor product pages. Effective for conquest campaigns where you compete directly against alternatives.

### In-Market Audiences (DSP)

Target shoppers who have recently browsed or purchased in specific categories. Amazon knows who has been shopping for "wireless headphones" in the last 30 days based on actual shopping behavior.

### Lifestyle Audiences (DSP)

Target users based on long-term shopping patterns. "Fitness Enthusiasts" are identified by consistent purchases in fitness categories, not just a single search.

## ACoS Optimization

ACoS (Advertising Cost of Sales) is the metric that drives every Amazon advertising decision. Understanding and optimizing ACoS is the key to profitable Amazon campaigns:

| ACoS Range | Status | Action |
| --- | --- | --- |
| Under 15% | Highly profitable | Scale budget, expand keywords. Room to grow |
| 15-25% | Healthy | Optimize bids, test new keywords. Maintain efficiency |
| 25-40% | Marginal / Launch phase | Acceptable for new products building organic rank. Tighten over time |
| 40%+ | Unprofitable (usually) | Reduce bids, add negatives, pause poor performers. Unless launching |

**Break-even ACoS = your profit margin.** If your product has a 30% profit margin, any ACoS under 30% is profitable. During product launches, running above break-even ACoS is acceptable to build organic rank and reviews.

AI Agents optimize ACoS by continuously adjusting bids based on keyword performance, time of day, and conversion patterns. Synter monitors search term reports daily, harvests high-performing terms, and adds negatives for wasteful queries.

## Keyword Harvesting Strategy

Keyword harvesting is the systematic process of discovering converting search terms and promoting them to controlled campaigns:

- **Run automatic campaigns** to discover what search terms Amazon matches to your products
- **Analyze search term reports** after 7-14 days. Look for terms with 2+ conversions and ACoS below your target
- **Harvest winning terms** to manual campaigns with exact or phrase match at optimized bids
- **Add poor performers as negatives** in auto campaigns to stop wasted spend on irrelevant terms
- **Repeat weekly** for continuous optimization

**With Synter:** AI Agents automate keyword harvesting entirely. Synter analyzes search term reports, identifies high-converting terms, promotes them to manual campaigns, and adds negatives for wasteful queries. Every action includes the data that informed the decision.

## How Synter Automates Amazon Ads

Synter provides dedicated tools for Amazon Ads and Amazon DSP management through Amazon's official API:

| Tool / Script | What It Does |
| --- | --- |
| amazon_ads_create_campaign | Creates Sponsored Products, Brands, or Display campaigns with targeting and bidding |
| amazon_ads_get_campaigns | Lists all campaigns with status, budget, spend, and performance metrics |
| amazon_ads_pause_campaign | Pauses or resumes campaigns with a single command |
| amazon_dsp_list_campaigns | Lists DSP campaigns (v1 API) with budgets and flight dates |
| amazon_dsp_list_ad_groups | Lists DSP ad groups with delivery status and targeting details |
| amazon_dsp_pull_metrics | Pulls DSP performance reports (v3 API) with automatic date chunking |

**DSP v1 Migration:** Synter uses Amazon DSP v1 API endpoints for campaign management. The legacy /dsp/orders/ endpoints are deprecated and rate-limited. All Synter scripts use the current v1 endpoints with the required Amazon-Ads-AccountId header.

## Amazon Ads vs Google Shopping vs Meta

How does Amazon advertising compare to other e-commerce advertising platforms?

| Factor | Amazon Ads | Google Shopping | Meta (Facebook/Instagram) |
| --- | --- | --- | --- |
| User Intent | Ready to buy (product search) | Researching products | Browsing/entertainment |
| Targeting Data | First-party purchase history | Search queries + audiences | Demographics + interests |
| Attribution | Closed-loop (purchase on Amazon) | Cross-site (GA4, GCLID) | Pixel + CAPI |
| Key Metric | ACoS (ad cost / sales) | ROAS (revenue / ad cost) | ROAS (revenue / ad cost) |
| Best For | Amazon sellers, D2C brands | All e-commerce | Brand building, D2C |
| Avg CPC | $0.50-$2.00 | $0.50-$3.00 | $0.50-$2.00 |

For e-commerce brands selling on Amazon, Amazon Ads is essential. The closed-loop attribution and purchase-intent targeting make it the highest-ROI channel for Amazon sellers. Synter manages Amazon alongside Google and Meta for a unified [cross-channel strategy](https://synterai.com/blog/cross-channel-advertising-ai).

### What is ACoS and what is a good ACoS on Amazon?

ACoS (Advertising Cost of Sales) is Amazon's primary efficiency metric. It's calculated as ad spend divided by attributed sales, expressed as a percentage. A 'good' ACoS depends on your margins and goals: 15-25% is typical for established products, 30-50% is acceptable during launch phase for ranking, and under 15% indicates strong profitability. Your break-even ACoS equals your profit margin percentage.

### What is the difference between Sponsored Products and Sponsored Brands?

Sponsored Products promote individual product listings and appear in search results and product detail pages. They are the highest-volume, most straightforward ad type. Sponsored Brands promote your brand with a custom headline, logo, and up to three products, appearing at the top of search results. Sponsored Brands drive brand awareness and are available only to brand-registered sellers.

### What is Amazon DSP and who should use it?

Amazon DSP (Demand-Side Platform) is Amazon's programmatic display and video advertising platform. Unlike Sponsored Products which appear on Amazon, DSP ads appear across Amazon properties (IMDb, Twitch, Fire TV) and third-party websites. DSP is best for brands spending $10K+/month who want to leverage Amazon's first-party purchase data for off-Amazon retargeting and audience targeting.

### How does keyword harvesting work on Amazon?

Keyword harvesting is the process of discovering high-converting search terms from automatic campaigns and promoting them to manual campaigns with exact or phrase match. Run auto campaigns, analyze the search term report after 1-2 weeks, identify terms with good ACoS and conversion rates, add them as exact match keywords in manual campaigns, and add poor performers as negative keywords.

### Can AI Agents manage Amazon Ads automatically?

Yes. AI Agents can automate the entire Amazon advertising workflow: keyword harvesting from auto to manual campaigns, bid adjustments based on ACoS targets, negative keyword management, dayparting optimization, budget allocation across campaigns, and DSP campaign management. Synter's agents use Amazon's official SDK and API to execute changes with full transparency.
