Understanding TACOS

TACOS (Total Advertising Cost of Sales) measures your ad spend against your total revenue — including both ad sales and organic sales. While ACOS tells you how efficiently a campaign converts, TACOS shows you the bigger picture: how advertising is affecting your entire business.

How TACOS is calculated​

Formula: Total Ad Spend ÷ Total Sales (Ad + Organic) × 100

Example: You spend $30 on ads. Your total revenue from ads and organic sales combined is $300.

$30 ÷ $300 × 100 = 10%

Because TACOS includes organic revenue in the denominator, it is always lower than ACOS for the same product. That difference is valuable — it reflects how much of your business runs without advertising.

What TACOS benchmarks to watch​

RangeWhat it means
5–10%Strong organic presence. Your ads support growth without dominating your cost structure.
10–20%Healthy balance. Common for growing products still building organic momentum.
20%+Over-reliant on ads. Your organic sales may be too low relative to ad spend.
info

These benchmarks vary by product category, competition level, and product maturity. A new product launch will naturally have a higher TACOS — that is expected and normal.

Why TACOS matters more than ACOS long-term​

ACOS only sees ad-attributed revenue. TACOS captures the halo effect — the organic sales lift that advertising creates through improved keyword ranking, Best Seller badges, and increased brand awareness.

Here is what your TACOS trend tells you:

  • Declining TACOS over time — Your advertising is building lasting value. Organic sales are growing faster than your ad spend, meaning your brand is gaining traction on its own.
  • Flat TACOS — Your business is stable. Ad spend and total revenue are scaling together.
  • Rising TACOS — A warning sign. Organic sales may be slipping, or you are increasing ad spend without a proportional return. Time to investigate your listings, reviews, or competitive landscape.

The goal is not zero TACOS — advertising should always support your organic ranking. The goal is a declining trend, which means each dollar of ad spend is delivering more total value over time.

Strategies to improve your TACOS​

Since TACOS = Ad Spend ÷ Total Sales, you improve it by either reducing wasted ad spend or growing your organic sales:

  • Optimize your listings for organic ranking — Strong titles, bullet points, backend keywords, and A+ content help you rank higher organically, which increases the denominator (total sales) without increasing ad spend.
  • Increase your average order value — Bundles, multi-packs, or premium variants generate more revenue per sale, which lowers TACOS as a percentage.
  • Target long-tail keywords — Specific, lower-competition keywords often convert at higher rates with lower CPC, giving you more sales for less spend.
  • Plan around seasonality — Lean into peak shopping periods (Prime Day, Q4) when conversion rates are naturally higher and your ad dollars work harder.
  • Review your ad portfolio regularly — Pause campaigns or keywords with consistently high ACOS and no organic lift. Not every campaign needs to run forever.

How to track TACOS in AdTrix​

In Ad Manager, your TACOS appears alongside ACOS in the guidance panel at the top of the page. AdTrix shows:

  • Current TACOS value — your total ad spend as a percentage of all revenue
  • Trend arrow — whether TACOS is rising, falling, or flat compared to the previous period

TACOS is shown as an informational metric (no color badge) because there is no universal ACOS-to-TACOS ratio — the right TACOS depends on your product mix and business stage.

tip

Check your TACOS monthly rather than daily. Short-term fluctuations from promotions or seasonal shifts can be misleading. A 30-day or 60-day trend gives you a clearer picture of whether your advertising strategy is building organic momentum.
