What is ROAS and how is it calculated?

ROAS (Return on Ad Spend) measures revenue generated per dollar spent on advertising. It's calculated as: ROAS = Revenue from Ads ÷ Ad Spend. For example, a ROAS of 4:1 means $4 in revenue for every $1 spent on ads.

A good ROAS depends on your profit margins and business model. Generally, a 4:1 ROAS ($4 revenue per $1 spent) is considered good. However, businesses with high margins might profit at 3:1, while low-margin businesses might need 8:1 or higher.

What's the difference between ROAS and ROI?

ROAS measures gross revenue from ad spend (Revenue ÷ Ad Spend), while ROI measures net profit ((Revenue - Costs) ÷ Costs). ROAS doesn't account for profit margins or other costs, making it higher than ROI but useful for campaign optimization.
