Adding Negative Keywords to Pmax Campaigns

[Manas Bagul]

Hi, 

I have recently been working on a script to add negative keywords to pmax campaigns. Since this cannot be done via a negative keyword list, I found that Negative Words can be added via the Google Ads UI. 

But I have a lot of accounts which have pmax campaigns to which I want to add Negative Keywords. So, I shifted to Google Ads Script. But all I could find was functions to add negative keyword LISTS to campaigns. 

Is there such a provision for negative keywords as well?

Thanks and Regards,

Manas Bagul

Hi Manas, 

If you reach out to your account manager / Shopping team, they can add a negative keyword list to any PMAX campaign in your account.

Hi Manas,

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

@Sebastian, thank you for your input to the user query.

I would like to inform you that it is not possible to add negative keywords to your Performance Max campaign via the Google Ads Scripts.   Performance Max negative keywords are applicable to Search and Shopping inventory only. Please refer to the help center article Negative keywords in Performance Max campaigns to get more information. 

I hope this helps! Feel free to get back to us in case of any further queries.

Thanks,

Hi @Sebastian, 

The issue with manually adding these negative keywords is that I have a ton of accounts which have PMAX campaigns. Manually, it would take a lot of time.

Hi, 

I have already referred the link that you've provided me, but I wanted to do it via Ads Scripts. But since it isn't possible, I'll look for another solution.

Also, I don't know if it's a bug or whether Ads Scripts don't support the operation, but, the following piece of code gives me 0 PMAX campaigns as output. I have 1 active, 1 paused and 3 removed PMAX campaigns in the account I provide to the code. Note that when I put channel type as SEARCH, the code works flawlessly.

const pMaxCampaignIterator = AdsApp.campaigns().withCondition(`campaign.advertising_channel_type!="PERFORMANCE_MAX"`).get();

Would appreciate any help here.

Thanks and Regards,

Hi,

I would like to inform you that "AdsApp.campaign()" will work only for search and display campaigns. I would recommend you to use the AdsApp.performanceMaxCampaigns() to work with pmax campaigns. You can refer to the sample examples documentation for more information. If you would like to fetch the data for different types of campaigns, then you can use the reporting option available in Google Ads Scripts using campaign.advertising_channel_type condition. You can refer to the below sample query and you can use the query builder to add additional fields.

const pMaxCampaignIterator = AdsApp.performanceMaxCampaigns().get();

SELECT campaign.id, campaign.name FROM campaign WHERE 
campaign.advertising_channel_type IN ('DISPLAY', 'PERFORMANCE_MAX', 'SEARCH', 'VIDEO')

Feel free to get back in case of any further queries.
 

Thanks,

Hi, 

The "bug" I reported was a mistake on my part. I resolved it using the function you mentioned shortly after reporting it. Thanks for your response anyway.

Hi Manas,

you can follow Sebastian's suggestion to have the support team attached negative keyword list(s) to your PMax campaigns, and then use scripts to add negative keywords to the list.

See details:

Hope this helps,
