What is ROAS?

Return on Ad Spend (ROAS) is a marketing metric that measures the revenue generated for every dollar spent on advertising. It helps you understand the effectiveness of your advertising campaigns and optimize your marketing budget.

A ROAS of 4:1 means you earn $4 for every $1 spent on advertising. Most businesses aim for a minimum ROAS of 3:1 to remain profitable after accounting for other costs.

Frequently Asked Questions

What's the difference between ROAS and ROI?

ROAS measures revenue per ad dollar spent, while ROI accounts for all costs (including COGS) and measures actual profit from investment.

What is a good ROAS?

A ROAS of 4:1 or higher is generally considered good. However, this varies by industry, margins, and business goals.

Can ROAS be negative?

ROAS is expressed as a ratio and is always positive, but a ROAS below 1:1 means you're spending more on ads than you're earning in revenue.

Optimize targeting, improve ad creative, refine landing pages, and test different bidding strategies to boost ROAS.
