Questions to Ask Before Hiring an Amazon PPC Agency

Hiring the wrong Amazon PPC agency costs you twice: the fee you pay, and the months of wasted spend and lost rank you only notice later. The problem is that most sellers interview agencies with the wrong question. “Can you lower my ACoS?” is easy to say yes to and tells you almost nothing. This is the checklist of questions that actually separates a profit-first partner from an ads-only vendor, so you can vet any Amazon PPC agency in 2026 with confidence.

Decide What “Good” Looks Like Before You Interview Anyone

You cannot vet an agency against a standard you have not set. Before the first call, know three things: your break-even ACoS and real margin (so you can judge whether their targets make you money), the difference between ACoS, TACoS, and actual profit (so you know what to hold them to), and your own scope, catalog size, marketplaces (US, UK, CA, DE), and how much of your time you can give. An agency that asks you these questions back is already showing better instincts than one that just promises a lower ACoS.

Strategy and Process Questions

• How do you structure campaigns? Look for a clear role for Sponsored Products, Brands, and Display, not one giant campaign. See our breakdown of SP vs SB.
• How do you harvest search terms and use negatives? A real answer describes promoting converting terms into exact campaigns and negating waste on a cadence. Vagueness here means guesswork.
• Do you treat listing conversion as part of PPC, or ads only? This is the single most revealing question. If a listing does not convert, more ad spend just burns faster. The right answer connects the two.
• How do you set bids relative to unit economics? Bids should trace to margin and conversion rate, not to Amazon’s suggested bid alone.

Metrics and Reporting Questions

• What KPIs are in the weekly and monthly reports? You want to see spend, sales, ACoS, TACoS, and trend, not a single vanity number.
• Do you report TACoS and organic contribution? ACoS alone hides whether ads are building organic rank or just renting sales. TACoS shows the real picture.
• How transparent is search-term and wasted-spend visibility? You should be able to see where money went, not just a summary. A “proprietary black box” with no search-term detail is a warning sign.
• Will I get listing and conversion recommendations, not only bid changes? A profit-first partner tells you when the listing, not the bid, is the bottleneck.

Access, Ownership, and Risk Questions

• Who owns the Ads account and historical data? The answer must be you. Your account, your data, your history, always. An agency operating inside your account with your permissions is normal; an agency that owns the account you would lose access to is a trap.
• What access levels do you need? Expect a request for advertising and reporting access through proper user permissions, following least-privilege practice. Confirm the specific roles against current Amazon Help rather than accepting a vague “we need full access.”
• How do you stay policy-safe while scaling? Growth should stay inside Amazon policy. An agency that shrugs at compliance is a liability as you scale.
• What happens if we part ways? You want documentation, a clean handover, and no hostage data. Ask this before you sign, not after.

Commercial Questions (Fees Without the Fog)

• Retainer, percentage of spend, or hybrid, and what am I actually buying? Each model has tradeoffs. Percentage of spend can reward spending more; a flat retainer rewards efficiency. Understand the incentive your fee creates.
• What is excluded? Creative, listing rewrites, Vine, and marketplace expansion are often extra. Know the real total, not the headline number. Our guide to PPC management cost goes deeper.
• How do you prove the fee is cheaper than the waste you remove? A confident agency can frame its fee against the wasted spend it eliminates and the growth it unlocks.

Red Flags When Vetting Amazon PPC Agencies

• Guaranteed page-one rankings or guaranteed ACoS numbers. Amazon does not publish its ranking formula and no one controls the auction. Guarantees mean guessing or worse.
• Ads-only thinking when conversion is the bottleneck. If they never mention your listing, they will spend your budget into a page that cannot convert.
• An opaque black box. No search-term visibility, no wasted-spend detail, “trust our system.” You should always be able to see where your money went.
• Pressure into a long lock-in before a clear scope. A confident agency earns the next month with results, not with contract length.

A One-Page Vetting Checklist

Bring this to any agency call: What is your campaign structure and harvesting process? Do you handle listing conversion or ads only? Do you report TACoS and profit, not just ACoS? Who owns my account and data? What access do you need and why? Retainer or percentage, and what is excluded? What happens when we part ways? Can you show real before-and-after context, not just star screenshots? If an agency answers all eight clearly and in plain language, they are worth serious consideration.

How AMZ Scaler Answers These Questions

Briefly, and by the same checklist: we structure campaigns by role and harvest search terms into controlled exact campaigns; we treat listing conversion as part of PPC because ad spend on a weak listing is wasted; we report TACoS and organic contribution, not just ACoS; you own your account and data; we work profit-first rather than chasing vanity ACoS; and we manage US, UK, CA, and DE. See real client results for the before-and-after context we mean.

Frequently Asked Questions

What questions should I ask before hiring an Amazon PPC agency?

Cover four areas: strategy (campaign structure, harvesting, whether they handle listing conversion), reporting (TACoS and profit, not just ACoS, plus search-term transparency), access and ownership (you should own your account and data), and fees (model, exclusions, and how the fee compares to the waste it removes).

Should an Amazon PPC agency control my advertising account?

They should operate inside your account with granted permissions, but you should own it. Never hand over an account you could lose access to. Confirm that your account, historical data, and campaign structure remain yours, with a clean handover if you ever part ways.

What metrics should an Amazon PPC agency report?

Spend, sales, ACoS, and crucially TACoS and organic contribution, plus search-term and wasted-spend visibility. ACoS alone hides whether ads are building organic rank or just renting sales. Good reporting also flags when the listing, not the bid, is limiting results.

How do Amazon PPC agencies typically charge?

Common models are a flat monthly retainer, a percentage of ad spend, or a hybrid. Each creates a different incentive: percentage of spend can reward spending more, while a retainer rewards efficiency. Always ask what is excluded, such as creative, listing rewrites, or marketplace expansion.

Is a lower ACoS always the right agency goal?

No. A very low ACoS can mean under-spending and leaving growth on the table, while a higher ACoS during a launch can be the right investment. The better goal is profitable growth measured by TACoS and margin, with ACoS as one input, not the sole target.
