change tROAS in a specific campaign with a script

[Antoine P]

Hi there,

I would like to change the tROAS of a campaign on Friday to 2.6  and change it again on Monday.

While Google Ads tells me it ran successfully, I see the script made no change to the campaign specified.

Can you please help me?

Here is the script:

function main() {
  var campaignName = 'Campaign A - PMax';
  var campaignIterator = AdsApp.campaigns()
      .withCondition("Name = '" + campaignName + "'")
      .get();
  while (campaignIterator.hasNext()) {
    var campaign = campaignIterator.next();
    var biddingStrategy = campaign.bidding().getStrategy();
    if (biddingStrategy instanceof
        GoogleAdsApp.BiddingStrategies.TargetRoasBiddingStrategy) {
      var newTargetRoas = 2.6;
      biddingStrategy.setTargetRoas(newTargetRoas);
    }
  }
}

Thanks,

[Sigurd Fabrin]

From your campaign name it appears to be a a pmax campaign. Those cannot be found using AdsApp.campaigns() - use AdsApp.​PerformanceMaxCampaign() instead

Hi Sigurd,

I just tried this and I got this error (see attached).

Thanks,

function main() {
  var campaignName = 'Campaign A - Performance Max';
  var campaignIterator = AdsApp.PerformanceMaxCampaign()

      .withCondition("Name = '" + campaignName + "'")
      .get();
  while (campaignIterator.hasNext()) {
    var campaign = campaignIterator.next();
    var biddingStrategy = campaign.bidding().getStrategy();
    if (biddingStrategy instanceof
        GoogleAdsApp.BiddingStrategies.TargetRoasBiddingStrategy) {
      var newTargetRoas = 2.6;
      biddingStrategy.setTargetRoas(newTargetRoas);
    }
  }
}

Error:  TypeError: AdsApp.PerformanceMaxCampaign is not a function

Hi All,

 

Thank you for reaching out to the Google Ads Scripts Forum Channel.

 

@Sigurd - Thank you for providing your insights to this.

 

@Antoine - I believe Sigurd’s recommendation is correct. You would need to use specific selectors for the different types of campaigns Google Ads Scripts supports. You may find them in the documentation here: https://developers.google.com/google-ads/scripts/docs/reference/adsapp/adsapp.

 

Upon checking the error you encountered, I would recommend to follow the sample implementation found in the documentation here <https://developers.google.com/google-ads/scripts/docs/reference/adsapp/adsapp_performancemaxcampaignselector>. The structure of the selector (or in your case, the iterator) should have a small `p` at the front of the word `performance`. Kindly refer to the snippet of code below:

var campaignIterator = AdsApp.performanceMaxCampaign()
   .withCondition("Name = '" + campaignName + "'")
   .get();

 

Let us know if you encounter any further issues or have any clarifications. If an error is encountered again, kindly provide your Google Ads account ID as well as the name of the script and a screenshot of the error so we’re able to further assist you. Kindly scrub any private data when posting information or images here as this forum is public.

 

This message is in relation to case "ref:_00D1U1174p._5004Q2mp8gv:ref"

Hi Antoine,

 

Kindly disregard the snippet of code that was previously sent and please refer to the snippet of code below:

var campaignIterator = AdsApp.performanceMaxCampaigns()
   .withCondition("Name = '" + campaignName + "'")
   .get();

 

Again, let us know if you encounter any further issues or have any clarifications. If an error is encountered again, kindly provide your Google Ads account ID as well as the name of the script and a screenshot of the error so we’re able to further assist you. Kindly scrub any private data when posting information or images here as this forum is public.

You're missing an 's'

It's not clear from the documentation, that I linked to before, but if you use autocomplete in the IDE, it will suggest the correct spelling

This time you have a ReferenceError. See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ReferenceError

Before you had a TypeError. See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypeError

The error message tells you what is wrong - This time you are referencing something you call GoogleAdsApp?

Hi Sigurd,

I have little knowledge of scripts. 

Here is the script. I don't know what is wrong.

function main() {
  var campaignName = 'All Products - TRoAS - Performance Max - pmax';

  var campaignIterator = AdsApp.performanceMaxCampaigns()
    .withCondition("Name = '" + campaignName + "'")
    .get();

  while (campaignIterator.hasNext()) {
    var campaign = campaignIterator.next();
    var biddingStrategy = campaign.bidding().getStrategy();
    if (biddingStrategy instanceof
        GoogleAdsApp.BiddingStrategies.TargetRoasBiddingStrategy) {
      var newTargetRoas = 2.6;
      biddingStrategy.setTargetRoas(newTargetRoas);
    }
  }

Thanks,

Hello Antoine,

I'm not from the official Google Ads Scripts team. However, I may be able to help you out.

If I understood correctly you want to change the target ROAS of a single (pMax) campaign to 260%?

If that is correct, you could try this script:

function main() { var campaignName = 'All Products - TRoAS - Performance Max - pmax'; var campaignIterator = AdsApp.performanceMaxCampaigns() .withCondition("Name = '" + campaignName + "'") .get(); while (campaignIterator.hasNext()) { var campaign = campaignIterator.next(); var biddingStrategy = campaign.bidding().setTargetRoas(260) } }

​

I've tested this script in one of my accounts, and it seems to work.

However, I do advise you to preview the script first, then execute it.

And once successful, you can schedule to script to run on Friday's.

Good luck!

Gr, Martijn

[Paulet, Antoine]

Hi Martijn,

Excellent. It worked!

Thanks a lot for jumping into this.

Wishing you a good day,

Thank you,
