You can pause or delete ads in AdWords at any time. For example, you may need to pause or delete ads that mention discounts or specials, which may be expiring. You should also periodically review ad performance data and pause low performers, such as ads with low CTR.
Decide if you'd like to pause or delete your ad. If you plan to run this ad again in the future, it makes more sense to pause it, rather than to delete it.
To pause or delete ads, perform the following steps:
Sign in to your AdWords account.
Navigate to the Campaigns tab and click on the Ads tab.
Select the ads you'd like to pause or delete by clicking the box in the menu bar.
Go to Edit and choose Pause or Delete.
When you pause or delete an ad, it stops that ad from showing. If you pause an ad, you can un-pause it at any time. However, if you delete an ad, you will not be able to un-delete it. You can still access a paused or deleted ad's history and performance data...
