What is a good ROAS for e-commerce?

A general minimum target is 3:1 to 4:1 ROAS, but the right target depends on your gross margin. If your margin is 60%, a 2:1 ROAS is profitable. If your margin is 30%, you need 4:1+ to break even. Calculate your break-even ROAS (1 / gross margin percentage) and aim for at least 1.5-2x that number.

Should I use ROAS or ROI to measure ads?

Use ROAS for day-to-day campaign optimisation (it is simpler and directly comparable across channels). Use ROI for strategic decisions about overall advertising investment (it accounts for all costs including product cost, fulfilment, and overhead). Both metrics are important but serve different purposes.

Why is my ROAS declining?

Common causes: increased competition raising CPCs, audience fatigue (same people seeing ads repeatedly), seasonal demand changes, ad creative becoming stale, changes in platform algorithms or attribution windows, or scaling spend too aggressively. Diagnose by analysing CPC trends, CTR changes, conversion rate shifts, and competitive landscape.

Return on Ad Spend (ROAS)

Return on Ad Spend

Also known as:ROASad returnadvertising return on investment

A metric measuring the revenue generated for every dollar spent on advertising, used to evaluate the effectiveness and profitability of e-commerce advertising campaigns.

In-Depth Explanation

Return on Ad Spend (ROAS) measures the revenue generated for every dollar invested in advertising. It is the primary metric for evaluating advertising effectiveness in e-commerce, directly linking ad spend to revenue.

ROAS calculation:

ROAS = Revenue from Ads / Advertising Cost
Example: $10,000 revenue from $2,500 ad spend = 4:1 ROAS (or 400%)
Can be expressed as a ratio (4:1) or percentage (400%)

ROAS benchmarks by channel (Australian e-commerce):

Google Search: 3:1 to 8:1
Google Shopping: 4:1 to 10:1
Meta (Facebook/Instagram): 2:1 to 6:1
LinkedIn: 2:1 to 4:1 (B2B)
Google Display: 1:1 to 3:1

ROAS vs. ROI:

ROAS: Measures revenue per ad dollar (top-line metric)
ROI: Measures profit per total investment (bottom-line metric)
A 4:1 ROAS with 50% gross margin means you earn $2 profit per $1 spent
Break-even ROAS depends on your gross margin

Factors affecting ROAS:

Product margins (higher margins allow lower acceptable ROAS)
Average order value
Customer lifetime value (repeat purchases from ad-acquired customers)
Targeting accuracy and audience quality
Ad creative quality and relevance
Landing page conversion rate
Competitive landscape and market conditions

ROAS optimisation strategies:

Improve audience targeting for higher-intent shoppers
Optimise ad creative through testing
Improve landing page conversion rates
Focus budget on highest-performing campaigns
Use automated bidding strategies (Target ROAS)
Retarget website visitors for lower acquisition cost
Optimise product feed for Shopping ads
