Amazon Advertising Metrics vs Real Client Results — Why Working With Experts Matters

When it comes to Amazon advertising, there’s a big gap between average performance and best-in-class performance.

At The Masked Consultants, we help brands cross that gap — and stay ahead of their competition.

Industry Advertising Performance Benchmarks

 

• • ACOS (Advertising Cost of Sale): Industry average is between 30%–35%
    (Meaning brands spend £30–£35 for every £100 of sales.)
    

• • TACOS (Total Advertising Cost of Sale): Industry average is between 12%–18%
    (Showing how much ads eat into overall revenue.)
    

• • ROAS (Return on Ad Spend): Industry average is between 3.5x–4x
    (£3.50–£4.00 revenue for every £1.00 spent.)
    

At these rates, profitability can be thin — especially when factoring in Amazon’s fees, shipping, and fulfilment costs.

The Masked Consultants’ Real Client Success Metrics

Here’s how our agency consistently beats those benchmarks:

 

• • Average Client ACOS: 18%
    (More revenue per £ spent on ads.)
    

• • Average Client TACOS: 9%
    (More efficient overall advertising impact.)
    

• • Average Client ROAS: 5.0x
    (Stronger returns from every advertising pound.)
    
    

And these aren’t one-off success stories — this is the average across our portfolio. We manage accounts across categories like Beauty, Home & Kitchen, Health & Supplements, Electronics, and beyond — and the results speak for themselves.

Why This Matters

In a competitive Amazon environment, small gains in ACOS, TACOS, and ROAS translate into:

 

• • Higher net profit per sale

• • Faster inventory turnover

• • Bigger reinvestment potential for growth

• • Stronger overall business valuations

Better ads = bigger business.
