What is Target ROAS Bidding Strategy in Google Ads?

Return on ad spend is one of the most important metrics to track in digital advertising. In simple terms, target ROAS tells you how much revenue you’re generating for every dollar you spend on advertising. For example, if you set a target ROAS of 200%, Google Ads will adjust bids to generate $2 on average in revenue for every $1 spent on advertising. The higher your ROAS, the more profitable your advertising efforts are.

To help you optimize your ROAS, Google Ads offers a bidding strategy called Target ROAS (tROAS). This bidding strategy is part of the automated smart bidding group, which means that it uses machine learning algorithms to automatically set bids based on historical performance data. With tROAS, you set a target ROAS value, and Google Ads uses historical data to automatically adjust bids to achieve that target. 

By setting a target ROAS and letting Google Ads do the heavy lifting, businesses can focus on other important aspects of their advertising campaigns. That being said, tROAS is not a set-it-and-forget-it solution. You still need to monitor your campaigns and know when to make adjustments. 

There are 6 types of automated Google Ads bidding strategies – Target ROAS being one of them. As an overview, the table summarizes the different types of automated smart bidding strategies and their goals.

What Is The Ideal Target ROAS?

When using the Target ROAS (tROAS) bidding strategy in Google Ads, one of the most important decisions that you need to make is what your target ROAS value should be. 

Truth is, there is no golden number. The ideal tROAS will vary from business to business and even from campaign to campaign, depending on a number of factors such as the industry, competition, and profit margins. 

A good place to start is the historical conversion value per cost data. Look at this figure for the ad group or campaign you’re interested in. Note that the tROAS you set can influence other aspects of your campaign performance, such as the amount of traffic your ad may get.

Note: Look at the conversion value/cost column in Google Ads to find this metric.

If you are just starting out and do not have historical data to look at, look at your business numbers. “How much do you need to generate in ROAS to be profitable or to break even?” You can that information and then apply it to your Google Ads campaigns.

In general, the ideal tROAS will be the one that maximizes revenue while keeping ad spend within the advertising budget. Arriving at your ideal ROAS will require careful monitoring and adjustment of tROAS targets over time, as campaign performance and market conditions change.

How to Set Up Target ROAS Bidding

Let’s move on to how you can start using this bidding strategy. Here is the step-by-step guide to setting up tROAS bidding.

Step 1: Set Up Conversion Tracking

Before you can use tROAS, you need to set up conversion tracking in your Google Ads account. This allows Google Ads to track the performance of your campaigns and adjust bids based on the target ROAS you set. You can read Google’s documentation on how to set up conversion tracking for your website.

Benefits of Target ROAS

One of the primary benefits of tROAS is that it allows you to focus on achieving a specific target return on investment (ROI). This can be especially useful for businesses that have specific revenue targets or profit margins that they need to meet. By using tROAS, advertisers can adjust their bids in real-time to ensure that they’re generating the highest possible ROI for their advertising spend.

Another benefit of tROAS is that it can be more efficient than manual bidding strategies. This is because the tROAS bidding algorithm uses historical performance data to make bid adjustments automatically, rather than requiring manual input and adjustment. This can save you time and resources, allowing them to focus on other aspects of their advertising campaigns.

Challenges of Target ROAS

However, there are also some potential challenges associated with tROAS. For example, if you set the target ROAS too high, it can limit the reach and performance of their campaigns. This is because the bidding algorithm may not be able to generate enough conversions at the target ROAS level to justify the ad spend. 

Another challenge is that tROAS bidding requires a significant amount of historical performance data in order to be effective. Specifically, most campaign types need a minimum of 15 conversions in the past 30 days. If you are running a new campaign or one with limited historical data, it may not be possible to use tROAS effectively.

That’s to say, If you have a specific ROI target that you need to meet, and you have sufficient historical performance data, then tROAS can be a powerful tool for optimizing return on ad spend. However, it’s important to be aware of the potential challenges and limitations of this bidding strategy and to be prepared to adjust strategies and targets as needed.


Target ROAS smart bidding strategy is a powerful tool for optimizing return on ad spend in Google Ads campaigns. By setting a target return on ad spend, Google Ads uses machine learning algorithms to automatically adjust bids and maximize ROAS. With careful setup and ongoing adjustments, it can effectively increase revenue and enhance campaign performance.
