Google Adwords

Find duplicate keywords
Unnecessary duplicate keywords can complicate your account management and skew performance statistics. Search your account for multiple instances of the same keyword, then edit or delete the duplicates as needed.

Advanced Maximum CPC changes
As your keyword lists grow, you may find yourself spending a lot of time editing Max CPC bids. The Advanced Maximum CPC changes tool helps you adjust bids by a specified percent or dollar amount, raise bids to the minimum CPC for all your inactive keywords, and more.

Keyword Grouper
Want to know one of the most important tips for success with AdWords? Create tightly knit Ad Groups with keywords and ad text that are based on a common theme. To help you do just that, AdWords Editor offers the Keyword Grouper. The Keyword Grouper takes an existing list of keywords and divides them into smaller Ad Groups based on common themes. You can then create related ad text for the new Ad Groups or have the choice of using existing ad text from within your account.

Managing multiple client accounts?
If you manage AdWords accounts on behalf of clients, you might consider using a My Client Center (MCC) - a helpful tool that allows you to access all the AdWords accounts that you manage under one easy login. As you can see from the image below, an MCC provides an easy-to-read dashboard with relevant information such as customer IDs, high level budget overviews, and spend information for your linked accounts. To access a specific account, simply click on the client account name to be taken to the Campaign Summary page for that account.
