ROAS (Return on Ad Spend)

Return on Ad Spend (ROAS) is the headline metric for paid acquisition. It's the ratio of revenue attributed to an ad campaign divided by the spend on that campaign.

ROAS = Revenue attributed to ads / Ad spend

A 3.0× ROAS means you generated $3 for every $1 spent. A 1.5× ROAS at a 30% gross margin means you're losing money on every order even though the campaign looks "profitable" in the ad platform.

Reported ROAS vs True ROAS

This is the trap that costs e-commerce stores six figures a year: the ROAS your ad platform reports is not the ROAS you're actually earning.

Reported ROAS is what Meta Ads Manager or Google Ads tells you. It includes:

• Conversions tracked via pixel/Conversions API.
• Conversions inside the platform's attribution window (often 7-day click).
• Conversions de-duplicated against the platform's own model.

True ROAS is what your bank account says. It's:

• Revenue your store actually received.
• Adjusted for refunds, chargebacks, and failed payments.
• Attributed across platforms without double-counting.

In practice, reported ROAS is 30-60% higher than true ROAS for most e-commerce stores running Meta + Google. The gap comes from:

• iOS 14.5+ tracking gaps that move conversions to "modeled."
• Cross-platform attribution overlap (Meta and Google both claim the same conversion).
• Returned and refunded orders that count as revenue.
• Failed-payment subscription conversions that never billed.

See True ROAS vs Reported ROAS for how to measure the gap on your own store.

Common ROAS benchmarks

A few rough numbers, varying by category:

• DTC e-commerce, prospecting: 1.5×-2.5× target ROAS is typical at scale.
• DTC e-commerce, retargeting: 4×-8× is normal.
• High-AOV / luxury: 0.5×-1.5× on prospecting is acceptable if LTV is high.
• Subscription / SaaS: ROAS is less useful than CAC / LTV ratio.

These benchmarks assume *true* ROAS. Reported ROAS at the same numbers usually means you're losing money.

How Omesta improves ROAS

Omesta improves ROAS in two ways:

1. Recover failed-payment revenue — every dollar recovered raises ROAS because it adds to the numerator without changing the denominator. 2. Identify wasted ad spend — Omesta's 135 ad-leak patterns catch dead-hour spend, audience overlap, creative fatigue, and tracking gaps. Killing wasted spend raises ROAS by lowering the denominator.

The median Omesta customer sees a 22% true-ROAS lift in the first 30 days.
