Google has just introduced Tag Manger – in a nut shell it allows you to deploy code once to your web pages and then add, edit and control Google Analytics, Adwords and more tags from dash board inside your Google account.

I also believe that this will ensure that Online Marketers do not have to rely on Web Developers to make regular small updates and changes.
Here is a great overview video from Google on this new service.
