What is ROAS and Why It Matters
ROAS (Return on Ad Spend) is the ratio of revenue from advertising to ad spend. If you spent $1,000 on Google Ads and generated $5,000 in revenue, your ROAS is 500%. For most e-commerce projects, the target ROAS ranges from 400–800%, although some of our clients have achieved over 1500%.
The main mistake is measuring only CTR and CPC. These metrics say nothing about profitability. ROAS is directly tied to your P&L.
Strategy 1: Separate Brand and Non-Brand Campaigns
Brand campaigns (where the keyword contains your brand name) typically have ROAS of 800–2000%, while non-brand campaigns see 200–400%. If you mix them together, your reported ROAS looks great, but you can't see the true efficiency of new customer acquisition.
Tip: Always exclude brand terms from non-brand campaigns using a negative keyword list. This gives you an accurate picture of ROAS for new customers.
Strategy 2: Set Up Proper Attribution
Most advertisers use last-click attribution, which gives an incomplete picture. For e-commerce, we recommend Data-Driven Attribution, which automatically distributes value across all touchpoints.
In Google Ads, go to Settings → Conversions → Attribution Model and switch to "Data-driven." You'll see which campaigns truly initiate the purchase journey.
Strategy 3: Segment by Product Margin
Not all products have the same margin. If your most popular product has 10% margin and a less popular one has 40%, you need different target ROAS for each.
Target ROAS formula: Target ROAS = 1 / Product Margin. At 25% margin, target ROAS = 400%.
Strategy 4: Optimize Performance Max Wisely
Performance Max is a powerful tool, but without proper setup it "eats" budget on brand terms and retargeting. Make sure to:
- Add all brand terms to an account-level exclusion list
- Upload high-quality images and videos (at least 5 variations each)
- Set target ROAS 20% above current — so the system doesn't reduce volume
- Give the campaign at least 6–8 weeks to learn
Strategy 5: Use Seasonal Bid Adjustments
Google Ads allows seasonal adjustments for Smart Bidding. Before peak season (Black Friday, New Year), apply +20–30% adjustments 2–3 days ahead. After peak, apply -20% for 5–7 days to stabilize the system.
Strategy 6: A/B Test Landing Pages
Even a perfect campaign won't deliver good ROAS with a poor landing page. For online stores, key testing elements include:
- Buy button placement
- Price and discount display
- Social proof (reviews, ratings)
- Page speed (each second = -7% conversion)
Strategy 7: Set Up Value-Based Retargeting
Not all visitors are equally valuable. Break retargeting audiences into segments:
- Added to cart but didn't buy (highest priority)
- Viewed a product 3+ times
- Purchased once 30+ days ago (repeat purchase)
- VIP customers (LTV above average)
Set different target ROAS and bids for each segment.
Conclusion
Increasing ROAS isn't magic — it's systematic work with data. Start with proper attribution, split campaigns by type and margin, and you'll see results within the first 2–4 weeks. If you'd like us to audit your current campaigns, leave a request below.
