Introduction

Choosing the right Amazon advertising agency is a crucial decision for any advanced seller looking to improve ad spend efficiency and scale growth. With more sellers flooding the marketplace, the competition for ad space is tighter than ever. A well-matched agency can help you compete above your weight class, while the wrong one can drain your budget with little to show.

For sophisticated sellers managing large catalogs and tight margins, the decision comes down to asking the right questions. Not surface-level questions, but sharp ones that reveal how prepared an agency really is to handle complexity, automation, and performance at scale.

Key Metrics and Performance Indicators

You need an agency that makes data work for you. Smart agencies rely on performance metrics to guide every decision, starting with two key numbers: Customer Acquisition Cost (CAC) and Return on Ad Spend (ROAS).

1. What is your target CAC?

If they struggle to answer this, it’s a red flag. A serious partner should know the acceptable CAC for your product category, and be able to explain how they drive acquisition below that level without killing volume.

Do they customize CAC goals for each ASIN? Do they adjust bids in real time based on conversion rates or deal seasonality? These are good follow-up questions.

2. How do you calculate and report ROAS?

This seems basic, but it’s not. Some agencies puff up results by counting branded terms or unrelated sales that would have happened anyway. Real ROAS should isolate incremental revenue driven by ads. Ask what attribution model they use. Ask how often they refresh that data and if you can see it broken down by ASIN.

If they give vague answers, it likely means they rely too much on top-line reports and not enough on the real profit drivers.

Campaign Management Expertise

An advanced seller often runs hundreds of campaigns across Sponsored Products, Sponsored Brands, and Sponsored Display. Without a smart strategy, those channels trip over each other and eat into margins.

1. How do you prevent campaign overlap across SP, SB, and SD?

You want to hear terms like coverage mapping, brand halo separation, or ad type role definition. Better yet, they use AI systems that allocate ASINs and keyword groups dynamically so your campaigns don’t fight each other.

2. How do you structure keywords to avoid internal competition?

They should automatically detect keyword duplication across ad groups and prioritize highest-performing ones by match type and placement type. Agencies that bucket keywords by campaign object (like awareness, branded defense, or conquesting) tend to help reduce waste from overlapping bids.

If they say they just “keep an eye on it,” that’s not enough. Precision matters here.

Portfolio and Budget Management

Sellers managing dozens of ASINs can lose visibility fast if portfolios aren't structured strategically. Ask how they break up product groupings and how spend is managed.

1. How do you structure multi-ASIN portfolios?

There should be a clear system based on factors such as product lifecycle stage, price point, or sales velocity—not just random tagging or category grouping. Ask for examples. Do they isolate new launches in separate campaigns with tailored goals? How do they handle seasonal ASINs?

2. How do you allocate budget across campaigns?

Budget planning should be goal-based. Some campaigns exist to drive velocity, others to hold rank or defend branded space. Smart agencies apply dynamic budget caps based on goals, not just volume. Listen for details on how often budgets are adjusted and if that process is automated.

3. How often do you review and adjust?

If the agency isn’t reviewing performance daily and adjusting budgets at least weekly, they might be too slow to keep up with algorithm changes or sales trends. Ask what triggers bid increases or campaign pausing.

Compliance and Automation

Amazon has become strict with ad policies, and managing dozens of campaigns manually increases the odds of disapprovals or policy violations. Automation helps with both performance and compliance, but only when it’s built into the core strategy.

1. How do you manage ongoing compliance?

Look for answers that mention Amazon’s General Sponsored Products Rules (GSPR), and how their systems flag, pause, or edit non-compliant campaigns before they’re blocked. Responsive compliance features are a must if you're running high volumes.

2. What forms of automation do you offer?

The most competitive agencies use AI to adjust bids, redistribute budget, and even test creatives across campaigns. And it needs to be real-time—daily optimizations or manual reviews no longer cut it at scale.

Ask if their system can shut down campaigns that are wasting spend or scale up ones that are exceeding targets automatically.

Ensuring Effective Collaboration with Your Amazon Advertising Agency

Success depends on visibility and feedback—not a black box. Even the smartest tool or agency won’t help if communication is vague or updates are infrequent.

1. How do you handle communication and reporting?

Look for automated dashboard access, custom reporting by ASIN or campaign, and regular performance reviews. The agency should be giving you insights that help you make faster decisions. Every report should tie spend directly to revenue and use clear metrics.

2. How do you adapt to performance changes?

Markets shift fast. Agencies that wait for your prompt or ignore feedback won't keep your brand competitive. Ask how often they run performance checks, and how they'll adjust tactics if goals shift—or if new regulations or cost changes hit your category.

What Advanced Sellers Should Ask Before Committing

The right Amazon agency won't just manage your account. It will drive performance at scale, without extra handholding or complexity. But only if you ask the right questions before signing up.

Zero in on measurable outputs: efficient CAC, cleaner keyword structures, dynamic budget shifts, policy compliance, and real-time optimization. If the agency lags or gives loose answers, it’s a warning.

Advanced sellers need better control, better reporting, and smarter systems—not more people doing manual adjustments. The best agencies have already replaced outdated workflows with intelligent automation. Your job is to find the one that proves it.

Now that you know what to ask, hold your agency to a higher standard. Better inputs, better structure, and better questions will get you better results.
