Frequently Asked Questions

What is TACoS on Amazon?

TACoS (Total Advertising Cost of Sale) = (Ad Spend ÷ Total Sales) × 100. Unlike ACoS, TACoS includes ALL sales (organic + ad-attributed), showing total advertising impact on your business.

What is a good TACoS for Amazon?

Good TACoS is typically 5-15%. Under 10% TACoS suggests healthy organic sales. TACoS above 20% may indicate over-reliance on advertising. Track TACoS trends over time.

Why is TACoS more important than ACoS?

TACoS shows advertising efficiency across your entire business. Low ACoS with high TACoS means you depend on ads for most sales. Ideally, ACoS can be high while TACoS stays low through organic growth.

How do I lower my TACoS?

Lower TACoS by: 1) Building organic ranking through reviews and SEO, 2) Improving conversion rate, 3) Creating brand awareness, 4) Optimizing listings for organic search, 5) Building repeat customers.
