Amazon PPC management: what the work actually is, week by week.

Amazon PPC management is not one thing. It is a fixed list of recurring tasks — most of them mechanical, a few of them genuinely judgement — and knowing which is which is what tells you whether to hire a person, buy a tool, or do neither. "PPC management" is sold as a service, a job title and a software category, and all three describe different work. Before you pay for any of them it is worth being precise about what the job actually is.

Here is the actual job, broken into the tasks that recur.

The weekly work

Search term review. Pull the search term report, find terms that spent money without converting, add them as negatives. This is the single highest-return recurring task in Amazon advertising and it is almost entirely mechanical. It takes 20–40 minutes a week on a focused catalogue and it compounds: every negative you add stops paying out forever. We went through the mechanics in how negative keywords cut wasted spend.

Bid adjustment. For each keyword, decide whether the current bid is too high, too low, or right. This is the task everyone thinks PPC management is, and it is the one where judgement matters least and arithmetic matters most. Target ACoS × average order value × conversion rate gives you a ceiling. Most accounts have a large population of keywords bid well under their ceiling and a smaller population bid well over it, both at the same time.

Budget pacing. Campaigns that cap out before end of day are losing impressions at the hours you chose to be visible. Campaigns that never spend their budget are telling you the bids are too low or the targeting too narrow.

Placement adjustment. Top-of-search converts differently from rest-of-search and product pages. The percentage modifiers are worth setting deliberately rather than leaving at zero — see what the placement multipliers actually do.

The monthly work

Harvesting. Search terms that converted well in auto or broad campaigns get promoted into exact match, where you can bid them precisely. This is how an account gets structurally better over time rather than just cheaper.

Structure review. Are the campaigns still grouped in a way that reflects how the catalogue actually sells? Accounts drift — a campaign built around a hero ASIN in January is often carrying four unrelated products by June.

Negative sweep between campaigns. Where two of your own campaigns compete for the same term, you pay more per click than you needed to and split the conversion history across both, so neither accumulates enough data to be bid on well.

The quarterly work

Recompute break-even ACoS. Margins move. FBA fees move. A target ACoS set eighteen months ago against a margin that has since changed is the most common expensive mistake in Amazon advertising, and it is invisible until someone recalculates. If it has been a while, run the numbers again.

Full audit. A structured pass over the whole account rather than the campaigns you happened to open. The twelve checks we run is the version we use, in the order we use it. Any structured equivalent is fine; the point is that it is periodic and written down — and we run a free one on request if you would rather not.

What it costs, three ways

In-house. The weekly work is 2–5 hours for a focused catalogue and 10+ for a large one. At a loaded cost of $40–70/hour that is roughly $350–1,400 a month of someone’s time, and the real cost is usually that it is someone’s time — a founder or a generalist marketer doing it after their actual job, which means it happens fortnightly at best and drifts.

Agency. Typically 10–20% of ad spend, sometimes with a floor around $1,000–2,000/month. At $10k spend that is $1,000–2,000. At $50k it is $5,000–10,000. The percentage model means their fee grows with your spend whether or not their work does — a point worth negotiating rather than accepting.

Software. $50–700/month for most tools, some flat, some a percentage of spend, some hybrid. Cheaper than either alternative above roughly $10k/month in spend, more expensive than doing nothing below about $2–3k. The flat fee versus percentage-of-spend calculator prices a year of each at your own spend.

That last threshold is real and most vendors are quiet about it.

Under roughly $2,000–3,000 a month in ad spend, most paid tools do not earn back their fee. Amazon’s native rules plus bulk operations will get you most of the way. Anyone selling you software below that number is selling you time savings, not returns, and you should price it accordingly.

How to tell which one you need

Ask what is actually going wrong.

• "I don’t have time." → Software, or a VA with a checklist. The weekly work is mechanical.
• "I don’t know what to change." → An audit first, then decide. Buying a tool to answer a question you have not framed yet is how accounts end up with three subscriptions and no strategy.
• "My margins don’t work." → Neither. PPC software optimises clicks; it cannot fix unit economics, listing quality, or conversion rate. Fix those first or you will just buy the wrong traffic more efficiently.
• "I’m spending $30k+ and can’t see why ACoS moved." → This is the case where management genuinely earns its fee, from a person or a tool. At that spend a 10% efficiency gain is $3,000 a month.

The question underneath all of it

Whatever you choose, one thing determines whether the account stays fixed: can whoever manages it tell you why any given bid is what it is?

Pick five bids at random and ask. If the answer is "the tool set it" or "we raised everything 10% in June", the account will drift back inside a quarter, because nothing about how decisions get made has changed. That is true of agencies and software equally.

It is the thing we built Mirox around. Every bid it sets carries the reasoning with it — the conversion-rate estimate and how confident it is, which guardrails were checked, which constraint ended up binding, and what the bid would have been without it. Not a score. The actual chain. You can see what that looks like before talking to anyone.

And if you want to test it without changing anything: Simulation Mode runs on your live account in read-only for 30 days. Same account, same ASINs, same auctions — it changes nothing. At the end you get every bid it would have set differently from your current setup, the reasoning behind each one, and the CSV. That file is yours whether you buy or not, and the pricing is a flat fee either way.

The one-line version

Most of Amazon PPC management is a weekly checklist that rewards consistency over cleverness; pay for a person when the problem is strategy, pay for software when the problem is time, and fix the listing first when the problem is margin.

Common questions

What does Amazon PPC management include?

Weekly search term review and negative keyword additions, bid adjustments against a target ACoS, budget pacing and placement modifiers; monthly keyword harvesting and campaign structure review; and a quarterly recalculation of break-even ACoS against current margins.

How much does Amazon PPC management cost?

Agencies typically charge 10–20% of ad spend, often with a $1,000–2,000 monthly floor. Software runs roughly $50–700/month. In-house is 2–5 hours a week for a focused catalogue. Below about $2,000–3,000 in monthly ad spend, none of them reliably earn back their cost.

Can you manage Amazon PPC yourself?

Yes, for most catalogues. The recurring work is mechanical and needs only the Search Term Report and Bulk Operations. The binding constraint is usually consistency rather than skill — the tasks reward being done weekly and punish being done occasionally.

Is Amazon PPC software better than an agency?

They solve different problems. Software is cheaper above roughly $10k monthly spend and applies rules consistently. An agency brings judgement on strategy, creative and catalogue decisions that no bidding tool touches. The percentage-of-spend model is the thing to scrutinise: it grows with your spend whether or not the work does.
