Today I realized that I've wasted all the monthly budget in one week because of my bad campaign management. I did a little search over the Internet because I couldn't find a way to more an 'Ad group' from a 'Campaign' to another and I hit the jackpot. I've stumbled over Google AdWords Editor (~21 Mb).

Google AdWords Editor is good for:

• drag-n-drop actions
• make offline modifications and the post them online
• mass/bulk actions

This powerful tool is free and available for both Windows and Mac.
