Setting Target ROAS doesn't work for TARGET_ROAS?

[Brandon Cook]

I have a script running on my account that is adjusting Target ROAS based on the historical ROAS, with the intent being to adjust up if we can do better or adjust down if we're expecting too much.

The script works to set the new target if the strategy type is MAXIMIZE_CONVERSION_VALUE, but fails when the type is TARGET_ROAS. Here is the relevant portion of the script:

  var campaigns = AdsApp.campaigns().withCondition("campaign.status = ENABLED").get();
  while (campaigns.hasNext()) {
    var campaign = campaigns.next();
    var bidding = campaign.bidding();
    var adjustment = 2;
    var roas = ###; // A function is called here to get the historical ROAS
    if (roas > (bidding.getTargetRoas() + adjustment)) {
      bidding.setTargetRoas(bidding.getTargetRoas() + adjustment);
    }
    else if (roas < (bidding.getTargetRoas() - adjustment)) {
      if (bidding.getTargetRoas() - adjustment < 150) {
        bidding.setTargetRoas(150);
      }
      else {
        bidding.setTargetRoas(bidding.getTargetRoas() - adjustment);
      }
    }
  }

The error I get from bidding.setTargetRoas(number) states:
'[Campaign Name]' employs a TARGET_ROAS bidding strategy. This type of bidding strategy does not support target roas.​

In this case, the particular campaign it fails on is a campaign with type of Display.

Hi,

Thank you for reaching out to the Google Ads Scripts support team.

I would like to inform you that for updating bidding strategy to Target ROAS (display campaigns), you need at least 15 conversions for campaigns (with valid conversion values) in the past 30 days. I would suggest that you refer to this article for more information about requirements for setting Target ROAS bidding strategy.

If you are still facing the same issue even after meeting all the requirements, kindly get back to us with the Google Ads account ID/CID and name of the affected script.

You can share the requested details via Reply privately to the author option or a direct private reply to this email.

The ad account ID is 293-772-7861 and the campaign name is "Smart".

The campaign is already set to use Target ROAS as the bidding strategy and the current target is set to 200%. There are nearly 200 conversions valued around 5300 in the last 30 days.

The script is labeled as "Crashing Script" in the account. There is a secondary copy called "ROAS - Search/Smart" that doesn't crash, but it's because I have placed an if statement that only attempts to set target ROAS if the bidding strategy type is MAXIMIZE_CONVERSION_VALUE. However, setting target ROAS should also work when the strategy type is TARGET_ROAS.

Thanks,
