Frequently Asked Questions
What is the difference between ACOS and TACOS?
ACOS measures ad spend against only the sales directly attributed to those ads. TACOS measures ad spend against your total sales (ad-driven plus organic), giving a broader view of how advertising is impacting your overall business.
What is a good ACOS?
It depends on your profit margin — a breakeven ACOS equals your profit margin percentage. Many sellers target an ACOS meaningfully below their margin to ensure ads remain profitable rather than just breaking even.
Why track TACOS if ACOS already exists?
TACOS helps reveal whether your ads are driving organic growth too (a declining TACOS over time while sales grow suggests ads are boosting your organic ranking), which ACOS alone can't show.
