What Is Return On Ad Spend?
Return on ad spend, or ROAS, measures how much revenue your advertising generates for every rand you spend. It is calculated by dividing attributable revenue by ad cost. If a campaign spends R10,000 and produces R48,000 in tracked revenue, its ROAS is 4.8x.
ROAS differs from ROI in that it only considers ad spend, not the full cost of doing business. A campaign can show a strong ROAS and still be unprofitable once product costs, fulfilment, and overheads are included, which is why your target ROAS should be derived from your margins rather than borrowed from an industry benchmark.
Across the Juicy Designs client base, campaigns average 4.8x ROAS, roughly double the typical industry figure. That gap usually comes down to tracking accuracy, creative quality, and disciplined budget allocation rather than any single tactic.
Improving Your ROAS
The fastest ROAS improvements usually come from fixing conversion tracking so the ad platforms learn from accurate data, tightening audience and keyword targeting to cut wasted spend, and improving landing pages so more of the traffic you pay for actually converts.
Creative refresh cycles matter too. Ad fatigue quietly erodes ROAS as the same audiences see the same ads repeatedly. Reviewing frequency metrics and rotating fresh creative before performance decays keeps campaigns compounding instead of plateauing.
FAQ
What is a good ROAS in South Africa?
A ROAS of 4x or higher is generally considered good for South African e-commerce, meaning R4 in revenue for every R1 spent. Service businesses with higher lifetime values can be profitable at lower ROAS figures. Your break-even ROAS depends on your profit margins.
How is ROAS different from ROI?
ROAS divides revenue by ad spend only, while ROI accounts for all costs including product, fulfilment, and overheads. A campaign with 5x ROAS may have a much lower ROI once total costs are included. ROAS measures ad efficiency; ROI measures overall profitability.
How do I track ROAS accurately?
Accurate ROAS tracking requires conversion tracking with values passed to the ad platform, typically via Google Ads conversion tracking, the Meta pixel with the Conversions API, and GA4 e-commerce events. Server-side tracking improves accuracy as browser privacy controls tighten.
