Google Grants

From within your AdWords account, you can review the performance statistics of your ad campaigns. You will be able to view the number of times your ad was viewed (an impression), the number of clicks to your ad, etc. You can even track conversions, such as donations, newsletter signups, and volunteer registrations!

Since you have access to all of this valuable information at your fingertips, you can make strategic decisions on how to expand your account, as well as what poorly performing keywords and ad text to tweak.
