Google announced Friday that you can now pause your ads, keywords and sites in AdWords.
As of today, all AdWords advertisers can pause and resume keywords (for keyword-targeted campaigns), sites (for site-targeted campaigns), and ad creatives. As you can see from the picture below, this feature is functionally similar to the pause/resume feature on the Campaign Summary page - we've simply extended it to the keyword, sites and ad variations tabs.
Overall, SEMs are very happy with this feature. Here are some comments from a WebmasterWorld thread:
This is especially useful for those with ads in Premium Positions. You can create a new ad for your AdGroup, pause it, and then revert back to your original ad if you are unable to wait for the new one to reach a Premium Position
This is great news. I have been doing things like lowering bids to .01 to pause a keyword on a product that is out of stock. Likewise on ads, if the red is out of stock but the blue is in, I hate to keep changing the ad and loosing history and it didn't always make sense to set up different ad groups. This will help tremendously.
Both keyword and creative pauses are excellent features. Now I don't have to play around with seperate campaigns when dealing with clients 'special offers' such as Valentines day or christmas offers. thanks G-Ads team.
Good stuff Google.
