Amazon Ads Agency & Consultancy

Your ACOS improved. Your Amazon P&L did not. TACOS is the number that matters.

We manage Amazon against total advertising cost of sale and contribution after every Amazon fee — referral, FBA, storage and returns — because an efficient ad account on a badly-listed product is an expensive way to stand still.

On Amazon, advertising is downstream of the listing

Amazon is a closed loop: ads drive sales, sales drive organic rank, organic rank reduces the share of revenue you have to buy. That flywheel only turns if the product converts once someone lands on it. A listing with weak images, thin content, poor reviews or an unstable Buy Box will convert badly no matter how precisely you bid, and Amazon will charge you more per click for the privilege because relevance and conversion feed the auction. Most underperforming Amazon accounts are not badly managed ad accounts. They are well-managed ad accounts pointed at products that were not ready to receive the traffic — and because ACOS only measures advertised sales, the reporting never surfaces it.

Platform-reported conversions versus booked revenue. Four advertising channels each report a share of the same conversions — Meta, Google, LinkedIn and YouTube. Because each measures inside its own attribution window with no visibility of the others, their combined claimed total is larger than the revenue actually recorded in the ledger.

Illustrative. Each platform reports the conversions it believes it influenced, inside its own attribution window, with no visibility of the others — so the same order gets claimed more than once and the totals exceed what finance booked. The gap widens with every channel you add.

Symptoms, causes and what they cost

ACOS is down but total profit has not moved

Why it happens: ACOS measures spend against advertised sales only. Cutting spend on discovery campaigns improves it while shrinking the organic rank those campaigns were feeding. The ratio improves as the business contracts.

What it costs: You optimise a ratio while total contribution falls, and the dashboard congratulates you.

Sales look profitable until Amazon's fees are applied

Why it happens: Referral fees, FBA fulfilment, storage, and returns rarely appear in the advertising view. A 20% ACOS on a product with a 35% total fee load and a 12% return rate is not a profitable product.

What it costs: You scale spend on items that lose money per unit, and it only shows up in the settlement report.

Rank and sales drop suddenly for no visible reason

Why it happens: Usually the Buy Box. Losing it to a competing seller or going out of stock stops conversion dead while ads keep spending, and the rank decay that follows takes far longer to recover than the outage lasted.

What it costs: You pay for traffic that cannot convert, then pay again to rebuild the rank you lost.

Spend keeps rising on the same handful of terms

Why it happens: No harvesting discipline: broad and auto campaigns are never mined for converting search terms, and non-converting terms are never negated. Budget concentrates on expensive head terms.

What it costs: Cost per click climbs on your most contested keywords while cheaper converting long-tail demand goes unclaimed.

Where growth is normally stuck

Conversion signal loss between the browser and the ad platform. Conversions fall at each stage of browser-side collection: tracking prevention and consent choices remove roughly a third, and further loss occurs before the event reaches the ad platform. A final bar shows the larger share that survives when events are also sent server-side.

Illustrative. Browser-side collection loses signal to tracking prevention, consent choices and blockers before it ever reaches the ad platform. Server-side events recover much of that gap — not all of it, and never the part a visitor declined.

Our solutions — matched to the problem you have

Our services

Retail readiness

The gate on everything downstream. Amazon prices your clicks partly on how well your listing converts, so this is an advertising lever, not a merchandising afterthought.

Marketplace buying

Sponsored Products, Brands and Display run as one system with a harvesting discipline, managed against TACOS and contribution.

Conversion & retention

Where the funnel rather than the ad is the binding constraint, more traffic makes the problem more expensive rather than smaller.

What we actually do on an Amazon account

We treat the ad account as one input into a retail system. The sequence matters: readiness, then structure, then scale — because spending into a listing that does not convert simply teaches Amazon that your product is a poor result.

How it runs

The engagement sequence, phase by phase. Four sequential phases, beginning with diagnosis and measurement before any campaign changes are made.

The order is deliberate. Acquisition work built on unreconciled measurement compounds the error, so the measurement layer is corrected before any campaign changes.

Days 1–10 — Assess the catalogue before the campaigns

Read-only access to Seller or Vendor Central and the ad console. We score retail readiness per ASIN, rebuild per-unit economics after all Amazon fees, and identify which products are actually worth advertising. Some will not be.

Weeks 2–4 — Fix readiness on the products worth scaling

Listing content, imagery, A+ modules, variation structure and review posture on the ASINs where the economics work. Advertising into an unready listing is the most expensive way to learn it was unready.

Weeks 4–8 — Restructure the account around harvesting

Discovery campaigns feeding exact-match structures, negatives applied systematically, Sponsored Brands defending your branded search, and budget concentrated on ASINs with contribution headroom rather than the ones with the best ACOS.

Ongoing — Manage the flywheel, not the ratio

Weekly against TACOS, contribution after fees, organic rank movement and Buy Box stability. When an ASIN cannot be made profitable, we recommend stopping rather than optimising it more efficiently toward a loss.

Why we start with the listing, not the bid

Amazon rewards conversion. A listing that converts well earns cheaper clicks, better placement and organic rank; one that converts poorly gets progressively more expensive traffic. That means the highest-return work in most accounts is upstream of the ad console entirely — and it is work a spend-based agency has no incentive to prioritise, because fixing a listing does not increase billable media. We price on scope, so recommending that you spend less until the product is ready costs us nothing.

What you get out of it

You know which ASINs deserve budget

Per-unit contribution after every Amazon fee, so spend concentrates on products that make money rather than products with a flattering ACOS.

The organic flywheel starts working for you

When advertising drives conversion on a ready listing, rank improves and the share of revenue you must buy falls.

Budget stops burning during outages

Buy Box and stock monitoring tied to spend means you stop paying for traffic that structurally cannot convert.

Reporting survives the settlement report

Contribution after referral, FBA, storage and returns — the number your finance team will recognise.

Cumulative contribution against customer acquisition cost over twelve months. Contribution accumulates month by month as a rising line, while acquisition cost is a flat line paid up front. The two cross once cumulative contribution overtakes acquisition cost. The shaded area before that crossing is the payback period, during which capital is committed.

Illustrative. Contribution accumulates monthly while the acquisition cost is paid up front. The shaded area is the period your capital is committed — the real constraint on how fast you can scale, regardless of how strong the LTV:CAC ratio looks.

Frequently Asked Questions

What is the difference between ACOS and TACOS, and which should we manage to?
ACOS is ad spend divided by advertised sales — it only sees revenue attributed to ads. TACOS is ad spend divided by total sales, including organic. TACOS is the more honest number because it shows whether advertising is building organic rank or merely substituting for it. A falling TACOS at stable total revenue means the flywheel is working; a falling ACOS with falling total sales usually means you cut discovery spend.
Our ACOS is good. Why would we need help?
A good ACOS on a product that loses money after referral, FBA, storage and return costs is not a good outcome. The first thing we rebuild is per-unit contribution after every Amazon fee. It is common for the ASIN with the best ACOS in an account to be one of the least profitable once the full fee load is applied.
Why do you look at our listings before our campaigns?
Because Amazon's auction rewards conversion. A listing with weak imagery, thin content or poor reviews converts badly, which makes your clicks more expensive and your placements worse. Advertising into it accelerates the spend without fixing the constraint. Fixing readiness first usually improves ad performance more than any bid change would.
Is Amazon DSP worth it for us?
Sometimes, and it should be judged on incrementality rather than last-click. DSP's value is usually upper-funnel and remarketing, both of which look poor under last-click attribution and can look very different under a holdout. We would rather test it properly than either dismiss it or sell it.
Do you handle the listing content or just advise on it?
We audit and specify it — titles, bullets, imagery requirements, A+ modules, variation structure — and work with your team or creative supplier to implement. Where you have no one to execute, we will say so up front rather than let the recommendation sit unactioned.
Do you charge a percentage of ad spend?
No. That model pays the agency more when your budget grows, whether or not the growth was profitable, and it makes recommending a spend reduction structurally irrational. We price on the scope of the work: $2,500 for a diagnostic audit, $4,500–$5,500 for a build sprint, $6,500–$8,500 per month for a retainer.
Do you work with companies outside India?
Yes. We are based in Bengaluru and work with companies across the US, UK, UAE, Singapore, Australia, Canada, New Zealand and Ireland. Engagements run remotely with working hours overlapping your timezone.
Who owns the tracking setup and models when we stop working together?
You do, entirely. Everything is built in your accounts under your credentials — server-side tracking configuration, unit-economics models, dashboards, playbooks. We do not hold code or withhold access at the end of an engagement.
Why can we not see your client names?
Our clients are under NDA, so engagements are described by sector and situation rather than named. We would rather show you a real result with the name withheld than a named logo we cannot substantiate, and we will walk you through the methodology and the measurement on a call.
