What is return on ad spend?
Return on ad spend (ROAS) is a marketing metric that measures the revenue a business earns for every dollar it spends on advertising. It’s a crucial metric for ecommerce shops because it helps determine the effectiveness of advertising campaigns and the overall health of a business’s marketing efforts.
How to calculate ROAS
1. Determine attribution
Attribution is the process of determining which marketing channels or touchpoints contributed to a sale. There are two main types of attribution models: single-touch and multi-touch.
Single-touch attribution
In a single-touch attribution model, 100% of the credit for a sale is given to one touchpoint. This could be the first or last interaction a customer had with an ad before making a purchase.
Multi-touch attribution
Multi-touch attribution models assign credit to all touchpoints that contributed to a sale. This can give a more comprehensive view of how different marketing channels work together to drive conversions.
2. Establish cost
Once you’ve determined attribution, you’ll need to establish the cost of your advertising efforts. This includes partner and vendor costs, affiliate costs, and the cost of clicks and impressions.
Partner and vendor costs
These are the fees paid to advertising platforms, agencies, or other partners for running ads on your behalf.
Affiliate costs
If you use affiliate marketing, you’ll need to factor in the commission paid to affiliates for driving sales.
Clicks and impressions
These are the costs associated with pay-per-click or display advertising campaigns, including the cost per click or cost per thousand impressions.
3. Use the ROAS formula
Once you have your revenue and cost data, you can calculate ROAS using the following formula:
ROAS = Revenue from ad campaign / Cost of ad campaign
What are the differences between ROAS, ROI, and CPA?
Return on ad spend (ROAS) measures the revenue generated from ad spend, while return on investment (ROI) measures the overall profitability of an investment, including ad spend and other costs. Cost per acquisition (CPA) measures the cost of acquiring a new customer through advertising.
