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.
- Sign in to Google Ad Manager.
- Navigate to Inventory
Ad units.
- Click Upload
- 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.
- Click Browse to find the CSV file you saved in step 4.
- 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.
- Click Confirm to create all of the ad units from your CSV file.
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
