Amazon PPC Consulting: What You're Actually Buying

What Amazon PPC Consulting Actually Means

"Amazon PPC consulting" covers three different purchases sold under one name. A solo consultant is one experienced person who plans keywords, sets bids, and reports back — usually the cheapest option and the most dependent on that one person's calendar. A boutique or full-service agency puts a small team on your account, often bundling PPC with listing work, creative, or storefront design. An enterprise agency runs Amazon spend as one channel inside a bigger multi-channel media buy, which fits brands already running search, social, and connected TV through the same shop.

None of these is automatically the right model. The question that actually sorts them is who is accountable for a bid decision on a random Tuesday, and how many other accounts that person is looking at while they make it.

How the Pricing Actually Works

Three structures cover most Amazon PPC consulting engagements: a flat monthly retainer, a percentage of ad spend, or a hybrid of both. A smaller group quote per project or won't publish pricing at all and route you to a call — which isn't a red flag by itself, but it means you're negotiating blind unless you ask directly.

The number that determines your real cost is the percentage, not the base fee, and it's the one most vendor pages leave vague. Take an account spending $60,000 a month on ads. A flat $2,500/month retainer runs $30,000 a year no matter what happens to spend. A pure 3% fee runs about $21,600 a year at that same spend level — but if the consultant grows your budget to $150,000/month because the plan is working, the fee grows to roughly $54,000/year with it. Neither structure is wrong. What's wrong is signing one without knowing which you agreed to.

• Ask for the percentage in writing, not just the headline fee.
• Ask if it's capped, and at what spend level the cap starts.
• Model your own worst case — what does the fee look like if spend doubles because the account is actually working?

What a Good Consultant Actually Does, Week to Week

Strip away the pitch deck and the job is mechanical: read the search term report, find where money is leaking, change one thing, watch what happens, keep it or reverse it. A consultant worth paying can tell you, for any live change on your account right now, why it's running.

The standard worth holding anyone to — a person, a team, or software acting on your behalf — is this: every proposed change carries the evidence behind it, a measurement plan, and a rollback trigger. If a consultant can't answer "what happens if this doesn't work," they haven't finished the plan. They've made a guess and started spending your budget on it.

The Mistakes That Burn Budget — Including Ours

The most common mistake is hiring on case studies and screenshots instead of the account itself. A logo wall proves a consultant has clients; it doesn't prove they'll read your search term report before touching your bids. Ask them to walk through how they'd structure your specific catalog, not a generic slide.

The second is judging everything on ACoS alone. A campaign can post a beautiful ACoS by starving the SKUs that actually carry your margin, or by capping spend on the keyword that was about to break out. TACoS and total profit tell you more than ACoS ever will.

We've made a version of this mistake too: quoting a target ACoS before the audit was finished, based on category averages, then walking it back once the account's real margin came in lower than assumed. The fix isn't promising a smaller number — it's not promising a number at all until the audit is done.

When the Results Don't Show Up

Give any structural change two to three full purchase cycles before judging it — roughly four to six weeks for most categories, longer for considered purchases. If ACoS or TACoS hasn't moved by then, don't wait quietly for the next monthly report.

• Ask for the measurement plan attached to the change when it went live. If there wasn't one, that's the actual problem, not the metric.
• Check whether the rollback happened. A consultant who tries something and leaves it running when it clearly isn't working is worse than one who never tried it.
• Re-check the fee against the result. If spend went up and performance didn't, you're paying more for the same outcome — say so plainly.

If none of that gets a straight answer, that's the signal to move, not the ACoS number itself.

Where Dr. PPC Fits

Everything above applies whether you hire a person, a team, or software. Dr. PPC, run by Full Circle, is a fourth option: it reads the account, writes a strategy per product against that brand's real economics, and proposes each change with the evidence, measurement plan, and rollback trigger described above already attached — you set how much of it runs without a human click, and inventory risk, pricing, new launches, and creative always come to a person regardless of that setting. Orbit, the analytics and tracking suite several names in this space charge for separately, is included at no extra cost. It runs $300/month plus 3% of ad spend, capped, month-to-month, with the first 30 days free. Full Circle has managed over $500M in revenue across 100+ brands, which is context for that number, not a claim it's the only right choice — a hands-on human consultant is still the better fit for a brand that wants a person, not a system, accountable for every decision.
