A healthy ecommerce brand should expect a blended ROAS of 3:1 to 5:1 from a PPC agency, meaning $3 to $5 in revenue for every $1 of ad spend. Prospecting campaigns often land at 1.5:1 to 3:1, while retargeting and branded search run 6:1 to 10:1 or higher. 1Digital Agency plans ROAS targets from your margins, not from an industry average, because the right number depends on what each sale actually earns you.
ROAS Benchmarks by Campaign Type
A single ROAS figure hides the mix behind it. Different campaign types do different jobs, and an agency that reports only one blended number can mask weak spots. Here is what typical ranges look like:
| Campaign type | Typical ROAS range | Main job |
|---|---|---|
| Branded search | 8:1 to 15:1 | Capture people already looking for you |
| Retargeting | 6:1 to 10:1 | Win back visitors and cart abandoners |
| Google Shopping / Performance Max | 3:1 to 6:1 | Capture product-intent demand |
| Non-brand search | 2:1 to 4:1 | Reach new buyers actively searching |
| Paid social prospecting | 1.5:1 to 3:1 | Build new audiences and demand |
These are planning ranges, not promises. Your category, average order value, and creative quality move them in either direction.
Why Break-Even ROAS Matters More Than Any Benchmark
Break-even ROAS is 1 divided by your contribution margin. If your margin after product cost, shipping, and fees is 40%, break-even is 2.5:1. Any ad spend returning less than that loses money on the first order.
- 25% margin: break-even ROAS is 4:1
- 40% margin: break-even ROAS is 2.5:1
- 60% margin: break-even ROAS is 1.67:1
A 3:1 ROAS is excellent for a 60% margin brand and a loss for a 25% margin brand. This is why a generic benchmark is a poor target. Set the floor from your margin, then set the goal above it.
What Affects the ROAS You Will Actually See
- Average order value: higher baskets absorb click costs better.
- Conversion rate: most ecommerce sites convert at 1% to 3%. A site converting at 3% can bid more aggressively than one at 1%.
- Repeat purchase rate: brands with strong repeat buying can accept a lower first-order ROAS.
- Tracking quality: broken conversion tags or missing server-side tracking understate or overstate results.
- Creative and product feed: weak images, titles, and offers cap performance regardless of bidding.
- Account maturity: new accounts spend the first 4 to 8 weeks gathering data before results stabilize.
What a Realistic Timeline Looks Like
Expect a learning phase in the first month, where ROAS is volatile and often below target. By months 2 and 3, a well-run account should show a clear trend toward your target. Judge an agency on the direction and the reasons behind movement, not on week-one numbers. An agency promising a fixed ROAS before seeing your margins, site, and tracking is guessing.
How 1Digital Agency Approaches ROAS
1Digital Agency is a digital marketing agency that runs paid advertising for ecommerce brands. Where we fit this question: we set ROAS targets by campaign type, anchored to your break-even point, rather than chasing one blended headline number. That means separating branded, retargeting, and prospecting results so you can see which spend creates new customers and which spend only collects existing demand.
Good reporting from any PPC partner should include:
- ROAS split by campaign type, not just blended
- Break-even ROAS stated next to actual ROAS
- New customer share of revenue
- Spend, revenue, and conversion rate trends month over month
- Plain-language notes on what changed and why
Red Flags When Evaluating a PPC Agency on ROAS
- A guaranteed ROAS before any account or margin review
- Reporting only blended ROAS, inflated by branded search
- No discussion of tracking accuracy or attribution
- Targets that ignore your margins and cash flow
- No distinction between new and returning customer revenue
Ecommerce PPC ROAS FAQ
What is a good ROAS for ecommerce?
A good ROAS is any figure comfortably above your break-even ROAS. For many brands that means 3:1 to 5:1 blended. A brand with a 25% margin needs at least 4:1 to break even, while a 60% margin brand breaks even at 1.67:1.
How long does it take a PPC agency to reach target ROAS?
Plan for 2 to 3 months. The first 4 to 8 weeks are a learning period where campaigns collect data and ROAS fluctuates. Steady improvement toward target by month 3 is a reasonable expectation.
Should I accept a lower ROAS to grow faster?
Yes, if you can afford it. Prospecting campaigns often run at 1.5:1 to 3:1 and bring in new customers who buy again later. If your repeat purchase rate and cash flow support a lower first-order return, accepting it can raise total profit over time.
