If the creative has not been sent to members, you may modify a message or discussion ad in an ongoing campaign. Once a message ad has been authorized and is currently delivered to members in an active campaign, it can’t be deleted.
Open your Google Ads account and sign in. On the left-hand menu, scroll down until you reach Campaign settings, then click it. You may modify the settings of your campaign in 2 ways: Check the box of any campaigns that you want to change and then save. Save your changes by clicking Save.
Click on the Ads Manager button. Select Campaigns under Advertising Managers. Check the box next to the campaigns you wish to modify. Under the reporting table, click Edit above.
To add settings from another campaign, click Edit and choose new preferences, or copy settings from an unrelated campaign. On the Locations tab, select or modify your new settings using View or edit.
To delete a campaign in Campaign Manager: Sign in to Campaign Manager. Select the correct account and campaign group name. Check the boxes next to the campaigns you’d like to remove. Select the Delete button. Click Remove to confirm the deletion.
