What is blended ROAS?

Blended ROAS (Return on Ad Spend) is your total revenue divided by your total ad spend across all channels. Unlike single-platform ROAS, blended ROAS gives you a true picture of your overall advertising efficiency — including the halo effect between channels.

What is a good blended ROAS?

A blended ROAS of 3× or higher is generally considered healthy for e-commerce. Below 2× typically means you're spending more than you're earning after costs. The ideal target depends on your margins — a 50% margin business needs at least 2× ROAS to break even on ad spend.

How do I improve my blended ROAS?

Start by identifying your highest-ROAS channel and shifting budget toward it. Pause campaigns with ROAS below 1.5×. Improve landing page conversion rates — a 10% improvement in CVR doubles the effective ROAS of every campaign. Review audience targeting and creative performance weekly.
