Set up Target ROAS bidding for Hotel Ads

Target return on ad spend (ROAS) helps you specify where you want your ROAS at the bid strategy level. Target ROAS is based on cost per click, and it optimizes bids against predicted conversion value as opposed to predicted conversion rate.

Target ROAS is suitable for you if you would like to automatically optimize bids to maximize ROI (return on investment). You can also choose Target ROAS if you have already passed or want to pass conversion values through Google Ads Conversion tracking pixel, imported GA goals, or offline imported conversions.


With Hotel Ads Target ROAS, you get several benefits that can help you save time and improve performance.

  • Spend less time managing bids
  • Use a diverse set of signals in your bid optimizations, including: device, location, browser, check-in date, and time of day
  • Only platform on the market to set a bid for each and every auction.
  • Smart bidding at no additional costs

Target ROAS lets you weigh each individual conversion action based on the total value it provides to your business. This gives you increased alignment between business and advertising objectives.

How it works

Things to note before setting up Target ROAS:

  • Conversion tracking implementation is required before setting up Target ROAS. Learn more about how to set up conversion tracking.
  • Only booking values is compatible with Hotel Ads campaigns.
  • Conversion category must be set to "Purchase" to be used for Hotel ads Smart Bidding campaigns (ECPC, tROAS).

The Target ROAS bid strategy uses Google AI to manage your bids in any Hotel Ads campaign. In practice, this means that if the Target ROAS determines that a user search is likely to generate a conversion with high value, Target ROAS will bid high on that search. If it determines that the search isn’t likely to generate a high-value conversion, it’ll bid low.

In addition to using Target ROAS, conversion value rules are also compatible with Hotel Ads campaigns. By using conversion value rules, like within Search campaigns, you can better express the value of conversions with Target ROAS as they relate to your business and easily adjust for conversions based on geographic location, device, and audiences at auction time bidding in real time.

There are 2 parts to setting up Target ROAS: add the bidding strategy to your account, and then tell it what return on ad spend it should target.

Step 1 of 2: Set up a Target ROAS bid strategy in your account
The animation represents how to set up tROAS (target return on ad spend) bidding for your hotel campaign in Google Ads.

  1. In your Google Ads account, click the Campaigns icon Campaigns Icon.
  2. Click the Campaigns drop down in the section menu, then click Campaigns.
  3. Hover over the campaign you want to edit and select the Settings icon.
  4. Under the “Bid settings”, click the “Bidding” drop down, and then click Change bid strategy. In the drop down menu under Change bid strategy, select “Maximize conversion value” and add the Target ROAS percentage by selecting the “Set a target return on ad spend (optional)” checkbox.
  5. Click Save.

Step 2 of 2: Select your target

Your Target ROAS is the average conversion value (for example, revenue) that you'd like to get for each dollar you spend on ads. Try setting a Target ROAS based on the historical conversion value per cost data for the ad groups or campaigns you'd like to apply this strategy to. As a general rule, look into the average conversion value divided by cost from the last 4 weeks.


Let’s say you’ve set the conversion value as $5 USD and the cost is $1 USD. Your tROAS will be 500% per following formula and calculation:

Conv. value / Cost * 100% = tROAS

5 / 1 * 100 = 500%

Keep in mind that the Target ROAS you set may influence the conversion volume you get. For example, setting a target that's too high may limit the amount of traffic your ads get. Learn more About Target ROAS bidding.

Monitor Target ROAS performance

Here are a few tips to check how Target ROAS is performing for your campaign:

Analyze over time

  • Consider giving the bid strategy at least 15 days to run before you evaluate its performance. Allowing this time to pass gives the strategy time to adapt.
  • Make sure that you have enough data to evaluate the strategy’s performance. Consider reviewing your data weekly as opposed to daily, especially if there is little traffic.
  • Consider that a number of factors may affect your results over a period of time. Your results may be affected by holidays, weekends, special events, changes to your campaign data, and your competitors in the auction.

Wait for changes

  • Account for conversion delays. Some conversions take more time than others, in some cases up to days or even weeks after a click. If you compare recent performance with past performance, your recent performance might not look as strong because of conversion delay. Learn how to Find out how long it takes for your customers to convert.
  • Change your ROAS targets to meet your changing marketing objectives. Target ROAS reacts to your target changes quickly, but may take some time to calibrate based on your conversion delay.

Track conversion value

  • Look at conversion value and then at conversion value divided by cost. This can help you verify that you’re getting enough sales and that you’re close to your Target ROAS.
  • Remember that Target ROAS might reduce your clicks. Don’t worry, because this is expected, since the bid strategy reduces bids for clicks that don't meet your target. It then uses the savings to bid higher for when a conversion seems more likely to meet your target. For the same reasons, your cost per click may go up and down.

Optimize campaigns

Here are a few tips to optimize a campaign that's using Target ROAS:

Increase conversion value

  • If you want to increase conversion value, consider gradually reducing the Target ROAS of your campaigns. This lets the bid strategy know you want to spend more for each conversion, so the strategy spends more to increase sales and conversion value.
    • If you're familiar with maximum CPC bidding, you can notice that reducing Target ROAS is the same as to increase your bid.

Review your strategy

  • Review your bid strategies and determine if each Target ROAS bid strategy gets at least 50 conversions per week at the campaign level and fully benefits from Target ROAS. Performance can improve with fewer, larger campaigns, and more conversions.
  • You might consider ways to make sure you remain competitive as other advertisers increase their bids. For example, bids might increase during a sales period or a change in season. In these cases, consider reducing your Target ROAS. The strategy will adjust your bids up, resulting in higher volume.
