Ad extensions add information about your business to your ads and typically boost your ads' performance. If you want to remove ad extensions, though, follow the instructions in this article.
To remove a manual extension from your campaign, check the box to the left of the extension(s) and click Delete. Removing an extension from one campaign won’t remove the extension from other campaigns.
With the exception of automated call extensions and automated message extensions, turning off an automated extension will stop it from showing with any ads in this account.*
To turn off an automated extension, follow these steps:
Sign into your AdWords account.
Click the Ad extensions tab.
In the “View” drop-down, select Automated extensions report.
Click Automated extension options (advanced).
Click Edit next to “Show all automated extensions for this account.”
Click Exclude specific automated extensions for this account.
Check the box next to the automated extension you’d like to turn off.
* When you turn off automated call extensions or automated message extensions, you block new automated extensions from being created, but existing automated extensions may still show with your ads. To remove existing call or message extensions, go to your "Ad extensions" tab, select "Call extensions" or "Message extensions" then remove the numbers you don't want to show.
