Create ad units in bulk

You can create multiple ad units at one time by uploading a CSV file into Google Ad Manager. If you need to update existing ad units or create more than 1,000 ad units at one time, use the Ad Manager API.

1. Sign in to Google Ad Manager.
2. Navigate to Inventory  Ad units.
3. Click Upload 
4. Click Download sample CSV file to download a file that you can use to define your ad units. Open the CSV file and make changes based on the examples and the descriptions in the table below. When you're done, save the CSV file using your file editor.
5. Click Browse to find the CSV file you saved in step 4.
6. Click Upload and validate to verify that the ad unit settings are correct. If you identify an issue with any of the ad units defined in your CSV file, click Back to re-upload a corrected CSV file.
7. Click Confirm to create all of the ad units from your CSV file.

If there is a problem with your upload, a message is displayed to let you know. The "View users, roles, and teams" user role permission is required to see this detailed message.

The sample CSV file

The sample CSV file contains fields and examples relevant to your network.

• Don't remove columns, or change the column order. Doing so results in a failed upload
• Delete header rows from bulk upload sample CSV prior to upload. If you don't delete header rows, the upload will likely fail
• Remove semicolon (;) from your file editor's list of delimiter or separator characters to ensure the sample file renders columns and values correctly
• Rows that begin with the pound (#) character are ignored when you upload the file

Columns in the sample CSV file

"Target platform" and "Mobile platform" were retired in April 2016 as ad unit settings and no longer available as bulk upload criteria. Do not include these columns in your bulk upload files.

The values for each column must follow the same formatting rules as when you create a single ad unit. Refer to the Create an ad unit article for definitions of each ad unit setting.
