Most sellers who hire an Amazon ads management agency see mixed results — not because the agency is bad, but because the relationship is set up wrong from day one. You hand over access, pay the monthly fee, and wait for results that may or may not come.
The strategies in this article fix that. Whether you're evaluating agencies for the first time or already working with one and not seeing the returns you expected, these are the specific things that separate high-performing agency relationships from expensive disappointments.
Each strategy is grounded in how Amazon Advertising actually works — Sponsored Products, Sponsored Brands, Sponsored Display, DSP — and what a competent agency should be doing across all of them.
Vague goals produce vague results. If you and your agency haven't agreed on what "working" actually looks like, you'll spend months in meetings where both sides talk past each other — one pointing to impression volume, the other wondering why profit margins haven't moved.
Before the agency touches a single campaign, lock in specific, measurable KPIs. TACoS (Total Advertising Cost of Sales), ACoS by campaign type, new-to-brand order rate, ROAS targets — these need to be written down, agreed upon, and tied to your actual business model, not industry averages pulled from a blog post.
Different goals require different strategies. A seller trying to defend market share on mature ASINs runs very different campaigns than one launching a new product and prioritizing new-to-brand customer acquisition. Your agency needs to know which one they're solving for.
1. Before the kickoff call, document your current TACoS, ACoS, and monthly ad spend so the agency has a real baseline, not assumptions.
2. Agree on primary KPIs for each campaign type — Sponsored Products, Sponsored Brands, and DSP often have different acceptable ACoS thresholds.
3. Set a 90-day benchmark review date in the contract, where performance is measured against the agreed KPIs and strategy is adjusted accordingly.
If an agency resists committing to specific KPIs, that's a signal. Competent agencies welcome defined targets because they know how to hit them. Resistance usually means they're planning to hide behind vague "optimization" language when results disappoint.
Inherited Amazon accounts are often a mess. Previous agencies or in-house managers may have built campaigns for convenience rather than control — broad match keywords doing the heavy lifting, no negative keyword structure, and campaign names that tell you nothing about what they're actually targeting.
Request a structured audit in week one. A good audit examines match type discipline (are broad, phrase, and exact match keywords being used with intention?), negative keyword gaps, campaign organization logic, and whether auto campaigns are being mined for search term data or just left to run.
The audit also tells you something about the agency itself. How they diagnose a broken account tells you exactly how they think about building a healthy one.
1. Ask the agency to deliver a written audit within the first 10 business days, covering campaign structure, match type distribution, and current negative keyword coverage.
2. Review the Search Term Report for the past 60 to 90 days yourself — look for irrelevant queries that have been spending without conversion.
3. Ask the agency to explain their recommended restructuring plan and why the existing structure is or isn't worth preserving.
Don't let an agency blow up an entire account structure in week one without a clear rationale. Restructuring mid-flight can disrupt campaign learning and performance history. Good agencies know when to rebuild and when to optimize what's already there.
Amazon offers Dynamic Bids (Down Only), Dynamic Bids (Up and Down), Fixed Bids, and Target ROAS or Target CPA options depending on campaign type. Many agencies default to "Up and Down" dynamic bidding and call it a day. That's not a strategy — it's a setting.
Understand exactly how your agency is building keyword lists, harvesting search terms from auto and broad campaigns, and making bid decisions. Full reliance on Amazon's automation is often a red flag, particularly for sellers with thin margins or highly specific conversion requirements.
A real keyword strategy includes a defined process for harvesting winning search terms from auto campaigns into manual campaigns, pruning underperformers, and adjusting bids based on conversion data rather than just impression share.
1. Ask the agency to walk you through their keyword build process — specifically how they identify seed keywords, how they use auto campaigns as a research tool, and how often they harvest new terms.
2. Ask what bidding strategy they use by campaign type and why — the answer should be specific to your margin structure and goals, not a generic default.
3. Request a monthly keyword change log so you can see exactly what's being added, removed, or adjusted and why.
Automation tools and Amazon's own Smart Bidding features can be useful, but they work best as a complement to manual oversight, not a replacement for it. If your agency can't explain what the automation is optimizing toward, you have a problem.
ACoS (Ad Spend / Ad Revenue) only measures the efficiency of your advertising in isolation. It tells you nothing about whether your ads are growing your business or simply taking credit for sales that would have happened organically anyway.
TACoS — Total Ad Spend divided by Total Revenue (ad revenue plus organic revenue) — gives you the full picture. If your TACoS is declining while your total revenue grows, your ads are building organic momentum and compounding your results. If TACoS stays flat while ACoS looks great, you may be running ads that are efficient but not actually growing anything.
Push your agency to report TACoS consistently. It's a standard metric in Amazon Seller Central and there's no reason a competent agency should be hiding it.
1. Pull your total revenue (ad + organic) from Seller Central and calculate your current TACoS so you have a baseline before the agency starts making changes.
2. Add TACoS as a required field in every weekly or monthly performance report your agency delivers.
3. Review TACoS trends over time — a gradual decline in TACoS alongside revenue growth is typically a sign that ad investment is building organic rank, not just buying clicks.
TACoS targets vary significantly by category, product maturity, and growth stage. A new product launch will naturally carry a higher TACoS than a mature ASIN with strong organic rank. Make sure your agency is setting TACoS expectations that reflect your actual situation, not a generic benchmark.
Wasted spend on irrelevant search terms is the most common budget leak in Amazon Ads. Without consistent negative keyword management, your Sponsored Products campaigns will spend real money on queries that have nothing to do with what you're selling — and that spend compounds quietly month after month.
Amazon's Search Term Reports, available in both Seller Central and Vendor Central, show you the exact customer queries that triggered your ads. Mining these reports for irrelevant terms and adding them as negatives is one of the highest-ROI activities in Amazon advertising. It's also one of the most frequently neglected.
Negative keywords can be applied at both the campaign and ad group level, and Amazon supports broad, phrase, and exact match types for negatives. A competent agency has a defined cadence for this — weekly for high-spend accounts, at minimum bi-weekly for others.
1. Ask your agency what their current negative keyword review cadence is and how they prioritize which terms to add.
2. Request a monthly negative keyword addition report — how many terms were added, at what match type, and what spend they were associated with before being blocked.
3. Review your own Search Term Report quarterly to spot patterns the agency may be missing, particularly in product category, competitor, or irrelevant modifier queries.
Be careful with broad negative keywords — blocking too aggressively can cut off legitimate traffic. The goal is precision, not paranoia. A good agency distinguishes between terms that are clearly irrelevant and terms that convert poorly but may still serve a brand awareness purpose.
Driving paid traffic to a weak listing is one of the fastest ways to burn through an ad budget. If your title is missing key search terms, your main image is poor quality, your review count is low, or your price is uncompetitive, no amount of bidding optimization will fix your conversion rate.
A good agency flags listing issues rather than running ads blindly and blaming low conversion rates when results disappoint. Amazon's algorithm factors listing quality into ad auction eligibility — a listing with strong click-through signals, solid reviews, and good inventory availability will perform better in paid placements than a weak one with the same bid.
Listing quality factors that directly affect ad performance include title keyword relevance, bullet point clarity, main image quality, A+ Content (available to brand-registered sellers), review count and rating, price competitiveness, and inventory availability. Your agency should be assessing all of these before scaling spend.
1. Ask your agency to include a listing quality assessment as part of their initial audit — not just campaign structure, but the ASINs being advertised.
2. Prioritize A+ Content for your top-spending ASINs if you haven't already. Amazon's own documentation notes that A+ Content can improve conversion rates, and it's a relatively low-effort improvement for brand-registered sellers.
3. Set a review threshold for new product launches — many experienced sellers avoid scaling paid spend until a new ASIN has a minimum number of verified reviews, since conversion rates below that threshold often make the economics difficult.
If your agency is consistently hitting impression and click targets but conversion rates remain low, the problem is almost certainly the listing, not the campaigns. An agency that won't tell you that directly is prioritizing their own metrics over your actual results.
Weekly dashboards without interpretation are noise. If your agency sends you a PDF with charts and no explanation of what changed, why it changed, and what they're doing about it, you're not getting reporting — you're getting data dumped on you and expected to feel informed.
Structure your reporting so it surfaces trends, explains decisions, and drives specific next actions. A well-run agency relationship includes a weekly performance snapshot (spend, ROAS, TACoS, notable changes) and a monthly strategy call where the agency presents what they did, what worked, what didn't, and what they're adjusting going forward.
The monthly call should feel like a business review, not a status update. You should leave it knowing exactly what the next 30 days of strategy looks like and why.
1. Define your reporting format upfront — which metrics you want tracked, at what frequency, and in what format. Don't let the agency default to whatever dashboard they use for every client.
2. Require written context with every report. Even two or three sentences explaining the week's key movements is enough to confirm the agency is actually watching the account, not just auto-generating reports.
3. Hold a monthly strategy call with a standing agenda: performance vs. KPIs, decisions made and rationale, upcoming tests or changes, and open questions from your side.
If your agency can't explain why they made a specific bid change or keyword decision in plain language, that's a problem. Good paid media management requires judgment, and judgment should be communicable. "The algorithm needed time to learn" is not an explanation.
Working with an Amazon ads management agency should compound your results over time — better data, tighter targeting, stronger listings, lower wasted spend. That only happens when you're clear on goals, demanding on process, and treating the relationship as a genuine partnership rather than a service ticket.
If your current agency can't answer basic questions about your TACoS, their keyword strategy, or why they're bidding what they're bidding, that's a signal worth acting on.
Start with the first two strategies before anything else. Define your KPIs before the agency starts, and demand an audit in week one. Those two steps alone will tell you whether you're working with a team that knows what they're doing or one that's going to spend six months optimizing the wrong things.
