The return on advertising spend (ROAS) is a key performance indicator in the digital marketing, that increase the efficiency of Advertising expenditure measures. It indicates the revenue generated per euro invested in advertising campaigns. This key figure is essential for companies to evaluate the success of their marketing activities, allocate budgets efficiently and increase the profitability of their advertising measures.
How is the ROAS calculated?
The calculation of ROAS is straightforward and is based on two main components: the revenue generated by advertising and the total advertising spend. The basic formula is:
ROAS = revenue from advertising campaigns / costs of advertising campaignsAlternatively, the ROAS can also be expressed as a percentage:
ROAS (in %) = (sales from advertising campaigns / costs of advertising campaigns) × 100An example: If a company invests €10,000 in an online marketing campaign and generates sales of €50,000, the ROAS is 5 (€50,000 / €10,000). This means that for every euro invested, 5 euros in sales were generated. Expressed as a percentage, this is 500 %.
When calculating, it is important to take all relevant advertising costs into account. This includes not only the direct click costs, but also other costs such as partner or provider costs as well as costs for ad creation and management.
ROAS and its importance for the marketing strategy
ROAS is an essential indicator for evaluating and optimizing the effectiveness of advertising campaigns. A high ROAS indicates profitable advertising expenditure and helps to achieve business goals.
- Efficiency assessment: The ROAS enables a quick assessment of which campaigns, channels or advertising formats work best and generate the highest sales.
- Budget allocation: By analyzing ROAS, a marketer can dynamically reallocate their budget to the channels and campaigns that perform best.
- Optimization potential: A low ROAS indicates a need for optimization. This can mean adjustments to target groups, bidding strategies or ad creation.
Differentiation from ROI
ROAS is often confused with return on investment (ROI) or used synonymously, although there are important differences. ROAS focuses exclusively on the ratio of sales to direct advertising expenditure.
ROI, on the other hand, considers the net profit in relation to the Total investments. In addition to advertising costs, other operating costs such as production costs, shipping, personnel and other overheads are also taken into account. It is possible to have a positive ROAS but still have a negative ROI if the other business costs exceed the revenue generated by the advertising. It is therefore advisable to keep an eye on both metrics to get a complete picture of campaign performance and overall profitability.
What is a good ROAS?
A „good“ ROAS cannot be determined across the board, as it depends heavily on factors such as industry, profit margins, business model and the specific objectives of a campaign. In principle, however, the ROAS should always be above 1 (or 100 %), as otherwise more money is spent on advertising than is generated in sales, which leads to losses.
Many companies aim for a ROAS of at least 4:1, which means that for every euro spent on advertising, 4 euros in sales are generated. In the E-Commerce, where margins are often lower, a higher ROAS of 5:1 or even 10:1 may be required to be profitable. For campaigns where the primary goal is brand awareness, a lower ROAS may be acceptable.
Optimize ROAS: Strategies for more success
The continuous optimization of ROAS is crucial for long-term success in performance marketing. The following strategies can help to increase ROAS:
- Conversion rate optimization (CRO): A higher Conversion rate leads to more sales with the same number of clicks and therefore to a better ROAS. Measures such as improving the user experience, fast Loading times, exit-intent pop-ups and optimized checkout processes are effective here.
- Target group refinement: Precise targeting reduces wastage and increases the relevance of the ads. The focus on the most profitable segments leads to more effective spending.
- Adaptation of bidding strategies: The use of automated bidding strategies such as „target ROAS“ in platforms such as Google Ads can optimize the bids to achieve a desired ROAS. Dynamic budget adjustments based on campaign performance are also important.
- Ad testing and creative optimization: Regular testing of different ad formats, headlines and call-to-actions helps to identify the best-performing variants.
- Product feed optimization (especially for shopping ads): A high-quality and optimized product feed ensures more relevant traffic and higher conversion rates.
- Focus on profitable products/services: Budgets should be concentrated more on offers with high margins and good ROAS.
- Maintain negative keywords: The addition of irrelevant Search terms as negative keywords prevents unnecessary costs.
