Erstens in Launch-Phasen: Hier kauft sich die Marke organisches Ranking und Reviews über aggressive PPC-Spends, der ACOS liegt oft 30 bis 50 Prozent über dem Break-even. Zweitens in Verdrängungskampagnen gegen direkte Wettbewerber, wo das Ziel nicht Profit pro Klick, sondern Marktanteilsgewinn ist. Drittens bei Top-of-Funnel-Keywords mit hohem Brand-Building-Wert, die später organische Sales triggern. Entscheidend ist die Trennung in Launch-, Performance- und Defense-Kampagnen mit jeweils eigenen ACOS-Zielen. Pauschal optimieren auf niedrigen ACOS verschenkt Marktanteile und friert organisches Wachstum ein." } }, { "@type": "Question", "name": "Was ist ein guter ACOS-Wert?", "acceptedAnswer": { "@type": "Answer", "text": "Es gibt keinen pauschal guten ACOS. Entscheidend ist der Vergleich mit dem Break-even ACOS, also dem Punkt, an dem Werbekosten und Marge ausgeglichen sind.

TACOS zeigt, wie effizient Werbung den gesamten Account-Umsatz unterstützt. Wichtig, wenn organische Rankings durch PPC-Investitionen aufgebaut werden. ACOS ist die Kampagnen-Metrik, TACOS die strategische Account-Metrik." } } ] }

ACOS (Advertising Cost of Sales): Strategy & Definition

What is ACOS on Amazon? – Definition & Relevance

The Advertising Cost of Sales (ACOS) represents the percentage ratio between advertising spend and the advertising revenue directly generated by it. It is one of the most important metrics in Amazon Advertisingfor evaluating the profitability of individual campaigns.

The mathematical basis (copyable):

ACOS = Advertising Spend / Advertising Revenue * 100

(Example: €200 in advertising costs / €1,000 in revenue = 20% ACOS)

Why we prioritize ACOS strategically:

  • Transparency of the cost ratio: It shows us at a glance what percentage of revenue is spent on generating sales.
  • Profitability Check: By comparing your profit margin (break-even ACOS), we determine the scope for aggressive scaling.
  • Synergy with ROAS: While ACOS focuses on costs, when combined with ROAS , it provides a complete picture of advertising effectiveness.

Our Approach: Strategic Management of the Cost Ratio

In our day-to-day operations, we never view ACOS in isolation. Drawing on over 10 years of marketplace management experience, we know that a low ACOS should not always be the goal if it results in the loss of valuable market share.

How we work with ACOS to help you succeed:

  • Defining Target Metrics by Phase: We distinguish between launch phases, during which we focus on visibility in Amazon SEO , and performance phases, during which we optimize for maximum profitability.
  • Granular keyword optimization: We identify cost drivers that aren’t relevant to conversions and reallocate budgets to segments that strengthen your market authority.
  • Comprehensive Account Health: We analyze the impact of advertising costs on total account revenue (Total ACOS) to ensure that your growth is sustainably supported by operational excellence.
