Frequently Asked Questions

Common questions on calculations, industry standards, and seller profit optimization.

Why is TACOS better than ACOS?

ACOS only looks at direct ad sales. TACOS looks at overall business health, showing if PPC ads are fueling organic sales velocity.

What is the formula for TACOS?

TACOS = (Total Ad Spend ÷ Total Organic + Ad Revenue) × 100. A TACOS between 8% and 15% indicates healthy organic momentum driven by advertising.

Why is a declining TACOS a positive sign?

A declining TACOS over time means your paid ads are driving organic keyword ranking and customer repeat purchases, growing total revenue faster than ad spend.
