ROAS
ROAS (Return on Ad Spend) is the most important metric for paid advertising. It shows how much revenue you generate for every dollar you invest in ads - and thus determines whether your campaigns are profitable.
What is ROAS?
ROAS is calculated by dividing the revenue from a campaign by the amount you spent on ads. If you spend $10,000 on Google Ads and generate $40,000 in revenue, your ROAS is 4.0 (or 400%).
Formula: ROAS = Revenue / Ad spend
A ROAS of 4 means that you earn $4 for every $1 you invest in advertising.
What is a good ROAS?
It depends on your profit percentage and your fixed costs:
- ROAS 2-3: Typically the minimum threshold to break even after purchasing and shipping.
- ROAS 3-5: Solid result for most online shops. Covers purchases, operations and makes a profit.
- ROAS 5+: Strong performance. Typically seen in brand searches or retargeting.
The right ROAS target for your online shop depends on your gross margin. If your gross margin is 60%, you can tolerate a lower ROAS than if your gross margin is 30%.
ROAS vs. ROI
- ROAS: Focusing only on the ad spend. ROAS 4 = £4 revenue per £1 ad spend.
- ROI: Includes all costs (purchasing, shipping, operations, advertising). Shows the real profit.
ROAS is easier to calculate and is used for daily campaign management. ROI is more accurate but requires a full overview of all costs.
ROAS across channels
- Google Search: Typical ROAS 4-8 for industry-specific search terms. High intent.
- Google Shopping: Typical ROAS 3-6. Visual format with product images and prices.
- Facebook/Instagram: Typical ROAS 2-5. Wider reach but lower intent than search.
- Retargeting: Typical ROAS 5-15. High because you reach people who already know your store.
- Brand searches: ROAS 10+. Customers searching for your brand name have already made up their minds.
How to improve ROAS
- Optimize conversion rate: Improvements in checkout, product pages and mobile experience lift ROAS for all campaigns simultaneously.
- Increase order value: Upselling and bundling increase revenue per conversion without extra ad spend.
- Sharpen targeting: Narrower audiences can result in fewer clicks but higher conversion rates and ROAS.
- Reduce waste: Add negative keywords in Google Ads, exclude irrelevant placements in Display and optimize bidding strategies.
- Use retargeting: Retargeting visitors and basket abandoners almost always yield better ROAS than cold-traffic campaigns.
ROAS limitations
ROAS is an important but incomplete metric:
- Attribution: ROAS depends on your attribution model. Last-click typically gives higher ROAS to brand and retargeting, while awareness campaigns are undervalued.
- New vs. existing customers: ROAS does not differentiate between new and returning customers. A low ROAS campaign that primarily drives new customers may be more valuable than a high ROAS campaign that only captures existing customers.
- CLV: ROAS only measures immediate revenue, not lifetime customer value. A new customer with a high CLV can justify a low initial ROAS.
