What our Amazon PPC management includes

Our Amazon PPC management services cover the three self-serve ad types in Seller Central. Those are Sponsored Products, Sponsored Brands (including video) and Sponsored Display. Amazon DSP, the programmatic display platform, is quoted separately. Vendor Central accounts are quoted separately.

A quick word on terms. PPC means pay per click: you pay Amazon only when a shopper clicks your ad. A search term is what the shopper typed. A negative keyword tells Amazon not to show your ad for a term.

Here is the work, how often we do it, and what you see.

Task How often What you see
Search term harvest (move winning terms into exact match) Weekly New keywords added, with their orders
Negative keywords (block terms that spend and do not sell) Weekly Terms blocked and the spend they cost
Bid changes Weekly Bids raised or cut, and why
Placement review (top of search, rest of search, product pages) Every 2 weeks Cost per sale by placement
Budget pacing Weekly; daily in Q4 Campaigns that ran out of budget
New campaign builds As needed Campaign names and goals
Written report Monthly ACoS, TACoS, spend, sales, changes made

Your account manager is an Amazon PPC specialist who does this work by hand, with software for the reports. No rule runs on your account that a person has not set and checked.

What changed in Amazon Ads in 2026, and what we do about it

That weekly list has grown, because Amazon added new places for your ads to show. Some of them switch on without you asking. Here is each change and what we check.

Campaign Manager (beta from 10 November 2025). Amazon launched one console for sponsored ads and DSP. Amazon says its smart search cut bid work time by 26%. What we check: that campaign names, budgets and reports still line up after the move.

Sponsored Products and Sponsored Brands prompts (US, 25 March 2026). These are short AI questions shown on search results and product pages. A tap can open the shopping assistant. Amazon bills them within your normal cost per click, and you can pause them. What we check: prompt clicks and sales against your other clicks. We pause prompts on campaigns where they cost more per sale.

Rufus became Alexa for Shopping (13 May 2026). Rufus is Amazon’s shopping assistant. Amazon’s own Rufus page now carries a note on the new name. What we check: that your listing answers the questions shoppers ask the assistant. Ads send traffic there, and a weak listing wastes it.

Alexa+ agentic ads (23 June 2026). Amazon extended prompts to Alexa for Shopping on Echo Show. What we check: whether these clicks show up in your placement data, and at what cost.

Creator placements (reported from 10 August 2026). Trade press reports that Sponsored Products ads now run inside Amazon Influencer content. The same reports say campaigns join by default, with a “Limit off-Amazon spend” control and creator exclusions. Amazon’s help page sits behind a login, so we confirm the settings inside each account. What we check: spend on these placements in week one, then we limit or exclude where sales do not follow.

How we start: your first 30 days

Those checks are part of the first month. Every new account follows the same dated plan, so you know what happens and when.

Days What we do What you get
1 to 3 Free audit: wasted spend, missing negatives, structure, placement costs Written audit with the top fixes ranked by dollars
4 to 10 Rebuild structure: auto, broad, phrase, exact and product targeting campaigns New campaign map, old campaigns paused not deleted
11 to 30 Harvest terms, add negatives, set placement changes from real data Weekly change log
30 First written report ACoS, TACoS, spend, sales, next month’s plan

We agree the scope in writing before day 1. If we miss that scope in the first 30 days, that month is free.

Who owns what. You own the ad account, the campaigns, the data and every report. We work through user access you grant in Seller Central, never on your login. If you leave, you remove our access and keep everything. Nothing we build sits in an account we control.

The bid math most sellers get wrong

The audit in days 1 to 3 finds the same problem again and again: bids that stack. Two settings multiply each other, and the real cost per click ends up far above the bid you typed.

Amazon offers three bidding strategies:

  • Dynamic bids, down only. Amazon lowers your bid when a click looks less likely to sell.
  • Dynamic bids, up and down. Amazon can raise your bid by up to 100% at the top of the first page. For all other placements, the cap is up to 50%.
  • Fixed bids. Amazon uses your exact bid every time.

On top of that, you can set placement adjustments. These raise your bid for one spot, such as top of search. Amazon allows up to 900%. Since 9 January 2024 that also covers rest of search.

Here is a worked example with a $1.00 bid.

Step Setting Highest possible bid
1 Base bid $1.00
2 Top of search +900% $1.00 x 10 = $10.00
3 Up and down bidding (up to +100% at top) $10.00 x 2 = $20.00

So a seller who meant to pay $1.00 has told Amazon it may pay $20.00. Most of those clicks will not cost $20.00. But the ceiling is there, and in a busy category it gets hit.

Our rule is simple. We start new campaigns on down only. We read the placement report for two to four weeks. Then we add placement changes only where the cost per sale earns them. We never run a large placement change and up and down on the same campaign without a reason in writing.

ACoS vs TACoS: what we report and why

Bid math shows what you pay per click. ACoS and TACoS show whether that spend pays off, and we report both every month.

  • ACoS (advertising cost of sale) = ad spend / ad sales.
  • TACoS (total advertising cost of sale) = ad spend / total sales, ads plus organic.

ACoS only sees sales from ad clicks. TACoS sees the whole store. If TACoS falls while total sales rise, your ads are lifting organic sales too. That usually means better organic rank.

Here is an example with made-up round numbers. It shows the pattern we look for, not a real account.

Month (example) Ad spend Ad sales Total sales ACoS TACoS
1 $3,000 $9,000 $20,000 33.3% 15.0%
2 $3,000 $9,500 $24,000 31.6% 12.5%
3 $3,000 $10,000 $30,000 30.0% 10.0%

ACoS barely moved here. A report with only ACoS would call this flat. TACoS shows total sales grew by half on the same spend. That is the number we steer by. If you want listings, stock and ads run as one job, see our Amazon account management service.

Proof: how we cut ACoS from 35% to 10%

That steering is how one account went from a 35% ACoS to 10% in six months. The Seller Central screenshot shows an ACoS of 9.96%.

The work was the same work in the table above, done every week. We cut spend on search terms that did not sell. We moved winning terms into exact match. We set placement changes from the placement report, not from guesses. We did not chase a lower ACoS by cutting every bid, because that also cuts sales.

The full story, with the screenshot, is in our ACoS case study. Every account is different, so treat it as proof of the method, not a promise of the same number.

Amazon PPC agency pricing: what it costs in 2026

Results matter, but so does the fee you pay to get them. Most agencies charge in one of three ways: a flat monthly fee, a percentage of ad spend, or a mix of both.

Model How it works Public examples
Flat monthly fee Same fee each month Third-party range: $500 to $2,000 a month for freelancers, $1,000 to $3,000 for boutique agencies (SalesDuo)
Percent of ad spend Fee rises with spend Third-party range: 10% to 20% of spend (SalesDuo); 15% to 30% at large agencies (Darkroom)
Hybrid Base fee plus a percent SellerMetrics: $900, $1,500 or $1,900 a month plus 1% to 4% of ad sales (SellerMetrics)

The ranges above come from other companies’ pages, not from us. Watch one thing with percent-of-spend deals. The agency earns more when you spend more, even if the extra spend does not pay.

GrowEventure pricing

We quote after the free audit, because the right fee depends on your ad spend, the number of ASINs and how much rebuild work the account needs. There is no setup fee, no lock-in, and you can cancel any month.

Every plan has no setup fee, a free audit, and no lock-in.

Will the fee pay for itself? Use this formula: monthly fee / your profit per sale = extra sales you need each month.

Say the fee is $500 and you make $8 profit per unit after all costs. $500 / $8 = 62.5. So you need about 63 extra units a month to break even. If you sell 20 a day now, that is about two more a day. If you sell 3 a day, it is a big ask. Run this before you hire anyone, us included.

Agency, software or do it yourself?

That break-even test also tells you if an agency is the right choice at all. Here is how an Amazon PPC agency compares with the other two options.

Option Cost Your time each week Who it suits
Do it yourself Your time only 3 to 6 hours, more in Q4 Small spend, one or two products, you like the work
PPC software Monthly tool fee 1 to 3 hours to check its rules You know PPC and want speed on bids
Agency Monthly fee (see above) About 30 minutes to read the report Larger spend, many products, no time

The time figures are our estimates from running accounts, not a study. Software is fast at bids. It does not decide your structure, write your negatives list with context, or tell you your listing is the problem. For deeper tuning ideas, read our Amazon PPC optimization guide. For a side-by-side of tools, see our Amazon PPC software guide. If you want to learn the basics first, start with our Amazon PPC guide.

When you should not hire us

Some sellers should not pay an Amazon PPC agency yet. Here is when we will tell you so after the audit.

  • Your ad spend is under about $1,000 a month. Our fee would eat most of any gain. Use our PPC strategy guide and run it yourself for now.
  • Your listing is not ready. Weak images, under 15 reviews, or a price out of line with rivals. Ads send people to the page, and the page has to sell. Fix it first, or look at our Amazon SEO services.
  • Your margin is under 20% after Amazon fees. Ads cost money per sale. No bid can fix a product that does not make enough per unit.
  • You want a promised rank or sales figure. We cannot give one honestly. Nobody can, since Amazon controls the auction.

These cut-offs are our working rules, not Amazon rules. A seller just under one of them may still be a fit.

Our guarantee

If none of those apply, here is what you get in writing.

  • One named account manager who knows the account.
  • A written report every month covering what changed and why.
  • Every file, login and asset stays the client’s.
  • No lock-in, cancel any month, no notice period.
  • No setup fee, and the audit before starting is free.
  • If we miss the scope agreed in the first 30 days, that month is free.

We do not promise a ranking, a Buy Box share or a sales figure, because those sit with the platform and not with us. We promise the work, the reporting and the terms above, and all three go in the contract.

Frequently asked questions

How much does an Amazon PPC agency cost per month?

Most sellers pay between $500 and $3,000 a month, based on third-party market ranges. Large agencies often charge 15% to 30% of ad spend instead. SellerMetrics publishes $900 to $1,900 a month plus a share of ad sales. GrowEventure plans start at The audit before we start is free, and there is no setup fee., with no setup fee.

Is a percentage of ad spend or a flat fee better?

A flat fee is usually better for sellers, because the agency gains nothing from pushing your spend up. A percentage deal can make sense at very high spend, where the work scales with budget. Whatever the model, ask how the fee changes if spend doubles and sales do not.

How long until Amazon PPC results show?

You should see less wasted spend within the first two to four weeks, once negatives and bid changes take hold. Structure and harvest gains take longer, often two to three months. In our ACoS case study, the drop from 35% to 10% took six months of weekly work.

How much should I spend on Amazon PPC?

Start with a budget you can hold for at least a month while data builds. Amazon suggests $10 a day as a starting budget for Sponsored Products, and the minimum is $1 a day. Scale up only on campaigns where the cost per sale fits your margin.

What is a good ACoS, and what is TACoS?

A good ACoS is one below your profit margin before ad costs, so each ad sale still makes money. TACoS divides ad spend by all sales, not just ad sales. A falling TACoS while total sales grow is the healthiest sign, because it shows ads lifting organic sales.

Who owns the ad account and data if I leave?

You do, always. We work through user access you grant inside Seller Central, never through your own login. Campaigns, reports, keyword lists and every file stay in your account. When you leave, you remove our access and keep all of it, with no notice period.

Should I hire an agency or use PPC software?

Use software if you already know PPC and want faster bid changes. Hire an agency if you lack the time or want someone to own structure, negatives and reporting. Many sellers with small spend do best running it themselves until spend passes about $1,000 a month.

Do you manage Sponsored Brands video and Sponsored Display?

Yes. We manage Sponsored Products, Sponsored Brands, including video, and Sponsored Display in Seller Central. We also review the 2026 placements such as prompts and creator placements. Amazon DSP and Vendor Central are quoted separately. We confirm the exact scope in writing before day one.
