What Is a Good Amazon TACOS? – The Complete Guide for Sellers
ACOS tells you if a campaign is efficient. TACOS tells you if your business is actually getting less dependent on ads over time. This guide explains what counts as good, by stage and by category.
There is no single good TACOS – there is a good TACOS trajectory for where your product is
A brand-new launch and a five-year-old bestseller should not be judged against the same number. What matters is whether your TACOS is moving in the right direction for your product’s stage – falling as a launch matures, and staying low and stable once a listing is established. That trajectory is what this guide focuses on.
Sellers who watch ACOS closely often ask the same follow-up question once they understand it – is a 25% ACOS actually fine if my organic sales are strong? That question is exactly what TACOS answers. Total Advertising Cost of Sales measures your ad spend against every sale you make, paid and organic combined, giving you a single number for how dependent your business is on advertising overall. A product can have a mediocre ACOS on paper and still be perfectly healthy if TACOS is low and falling, because organic sales are carrying most of the volume. This guide explains what counts as a good TACOS at different stages, how it differs from ACOS in practice, and the specific actions that bring it down sustainably.
🔍 What Is Amazon TACOS?
TACOS – Total Advertising Cost of Sales – is the percentage of your total revenue, organic and paid combined, that you spend on Amazon advertising. It is calculated as total ad spend divided by total sales, multiplied by 100. Spend $500 on ads in a month and generate $5,000 in total sales – organic and paid together – and your TACOS is 10%.
The key difference from ACOS is the denominator. ACOS only counts sales that advertising directly generated. TACOS counts every sale the product made, whether a buyer clicked an ad or found the listing organically. That makes TACOS a measure of how reliant your overall business is on paid traffic, rather than how efficient any single campaign is.
💡 Why it matters: A business built entirely on ads with no organic momentum is fragile – turn the ads off and sales disappear. A business with a low, falling TACOS has built organic rank that keeps generating sales even if ad spend is paused or reduced. TACOS is the metric that shows you which kind of business you are actually running.
⚙️ What Counts as a Good TACOS
A good TACOS depends heavily on where your product is in its lifecycle. Judging a brand-new launch against the same benchmark as a five-year-old bestseller leads to the wrong conclusions in both directions.
During launch – expect it to run high
A new listing has no organic sales history and no rank, so advertising is doing almost all of the work. A TACOS of 20% or higher is common and not necessarily a warning sign during the first few months, provided it is being spent to build sales velocity and reviews rather than wasted on poor targeting.
During growth – the trend should be falling
As a listing accumulates sales history, reviews, and organic rank, the same ad spend should be generating a smaller share of total sales because organic sales are picking up the rest. A TACOS that stays flat for months during this stage usually means organic rank isn’t building the way it should.
Once established – low and stable is the goal
A mature, well-ranked listing in a moderately competitive category often settles into a TACOS between 5% and 10%. Highly competitive categories may sit somewhat higher even at maturity, while low-competition niches can sit lower. The stable, low number reflects a product that sells well on its own, with ads adding incremental volume rather than carrying the listing.
✅ The practical implication: Track TACOS monthly and look at the trend line across at least three to six months rather than reacting to a single month’s number, since normal seasonality and promotions can shift it temporarily in either direction.
Want your TACOS trending down instead of stuck?
A PPC management approach built around lowering ad dependency – not just ACOS on individual campaigns – keeps TACOS falling as organic rank takes on more of the sales volume.
📢 TACOS vs ACOS – When to Use Each
ACOS and TACOS are not competing metrics – they answer different questions and are most useful when read together rather than in isolation.
💡 The smartest approach: Use ACOS week to week to manage individual campaigns and catch waste early. Use TACOS month to month to confirm the business overall is becoming less reliant on advertising as organic rank matures. A falling TACOS with a stable ACOS is usually the clearest sign an account is maturing correctly.
🛠️ How to Improve Your TACOS – 6 Steps
Because TACOS is a business-level metric, improving it involves both the advertising side and the organic side working together – not just PPC adjustments alone.
Every keyword that moves from relying on paid clicks to ranking organically lowers TACOS directly, since that sales volume now comes without ad spend attached. Prioritise keyword optimisation, review velocity, and conversion rate improvements on your highest-volume search terms first.
Run exact match campaigns on your priority keywords specifically to build the sales velocity signal Amazon’s algorithm rewards with organic rank. Once a keyword starts ranking organically, that sales volume no longer needs to come from paid clicks, which pulls TACOS down over time.
As a keyword climbs organically, gradually lower bids on it rather than leaving spend at launch-stage levels. Redirect that freed-up budget toward newer keywords or products that still need the same organic-building push.
A better main image, stronger bullet points, or improved A+ Content raises conversion rate across every source of traffic. Higher conversion means more total sales from the same visitor volume, which lowers TACOS without touching the ad account at all.
Traffic from social media, email, or influencer content that converts on Amazon adds to your total sales figure without adding to ad spend, directly improving TACOS. It can also contribute a ranking benefit under Amazon’s algorithm when tracked with Attribution links.
Set a monthly checkpoint to review TACOS trend against the previous three months, alongside your weekly ACOS management. This catches cases where campaign-level ACOS looks fine but overall ad dependency has quietly crept up, or vice versa.
Want organic rank and ad spend managed as one system?
Since TACOS improves fastest when SEO and PPC are working together, a coordinated Amazon solutions build treats keyword ranking and ad strategy as a single connected plan.
🚫 Common TACOS Mistakes
These are the misunderstandings that most often lead sellers to misjudge a perfectly healthy TACOS, or miss a genuine warning sign.
🛠️ Tools for Tracking TACOS
TACOS requires pulling both advertising spend and total sales data, so tracking it usually means combining Amazon’s native reports with a simple spreadsheet or a third-party dashboard.
Not sure if your TACOS trend is healthy for your category?
An account review comparing your TACOS trajectory against your product’s lifecycle stage and category competitiveness gives a clearer read than any single benchmark number can.
