A good ROI for Google Ads is considered anywhere between the ratio of 2:1 to 5:1. It means that any business generating 2 to 5 dollars in revenue for every 1 dollar spent has a good ROI. However, these are not fixed values and a “good” ROI can vary based on industry, competition, and specific campaign goals. While a 2:1 ROI is a common benchmark, most businesses aim to achieve 3:1 and 4:1 ROI. Some highly competitive industries might even aim for higher ROI, such as 10:1.
