A good return on ad spend (ROAS) varies depending on the type of advertisement and the industry. Generally speaking, an acceptable ROAS will be at least 1:1 or higher, and a good ROAS is typically around 3:1. This means that for every dollar spent, the return should be equal or greater than one. However, businesses should strive for a ROAS of 2:1 or higher to make sure that their advertising efforts are producing a positive return on investment.
