Google Adsense has rolled out its new ad management feature which allow publishers to manage ad units from within their account. However, some may not be able to experience this feature as Google is rolling this feature in phases.

According to Inside Adsense:-

This new ad management feature means that your ad unit settings (such as colors and channels) for new AdSense for content ad units will be saved in your AdSense account every time you generate ad code. Then, if you’d like to change any of these settings in the future, all you do is make the update within your account — you’ll no longer need to manually replace the ad code on all of your pages. For instance, you can quickly change the borders of all your 300×250 medium rectangles from red to blue with just a few mouse clicks. Fancy! We hope that this new feature will help you save time and will simplify the process of optimizing your ad units.

How do I find out if this feature is available for me?
Login into your Adsense account and click on Adsense Setup tab. If it is available for you, you will see “Manage Ads” link in your the sub menu.

If you prefer to stick to your “old” style of managing your ad units, you may do so as the old version of code will continue to work. You can read more about this new feature here or see it in action by viewing the video below.
