ROAS (Return on Ad Spend).
ROAS (Return on Ad Spend) measures revenue per advertising franc invested. Formula: Revenue ÷ Ad Spend. A ROAS of 4 means: for every franc invested, CHF 4 in revenue is generated. In e-commerce, a ROAS of 3–5 is considered good, above 10 is excellent.
ROAS (Return on Ad Spend) — Explained in Detail
ROAS (Return on Ad Spend) is one of the most important metrics in performance marketing. It measures how much revenue is generated for every franc invested in advertising. Formula: Revenue from advertising ÷ Ad spend × 100%. A ROAS of 4 (or 400%) means: for every CHF 1 in ad spend, CHF 4 in revenue is generated. ROAS is displayed directly in the dashboard by Google Ads, Meta Ads and other platforms.
What is a good ROAS? That depends heavily on industry, margins and business model. In e-commerce: ROAS 3–5 is considered good, ROAS 7–10 very good, above 10 excellent. In the B2B sector, ROAS is more difficult to measure as deals take longer to close (longer sales cycle). Here, CPL (Cost per Lead) is often more meaningful. A ROAS below 1 means loss per advertising franc — campaigns must be optimized immediately.
ROAS vs. ROI: ROAS measures revenue vs. ad spend. ROI (Return on Investment) accounts for all costs (cost of goods, agency fees, infrastructure). A ROAS of 4 sounds good — but if the product margin is 20%, the actual profit ROAS (after deducting all costs) is significantly lower. Always define your target ROAS based on your margin and costs.

In Google Search Network, a ROAS of 300–500% (3–5x) is a good benchmark. E-commerce often targets 500–1000%+. For B2B lead generation, ROAS is less relevant — use CPL (Cost per Lead) and CPA (Cost per Acquisition). Your target ROAS depends on your margin: if you have a 40% margin, ROAS must be above 250% to be profitable.
Key levers: 1) Keyword optimization (negative keywords, bid adjustments by search intent). 2) Landing page optimization (higher conversion rate = better ROAS). 3) Bidding strategy (Target ROAS bidding when sufficient conversion data is available). 4) Audience optimization (exclude underperforming demographics). 5) Ad copy testing (better click-through rates = cheaper clicks).
ROAS (Return on Ad Spend) = Revenue ÷ Ad Spend. It only considers direct advertising costs. ROI (Return on Investment) = (Profit - Investment) ÷ Investment. It accounts for all costs: goods, agency, production, shipping. A ROAS of 5 can mean a negative ROI if total costs exceed gross profit.
