Re: I have about one hundred keywords. How can I see which one works?
If you have a Search campaigns you just select the campaign in question and click on the Keywords tab. The table will show you your keywords' performance in a particular time frame that can be adjusted in the upper right corner.You may also want to click the Columns drop-down so as to customize the metrics you are shown.
If your campaign is running on the Display Network, first click on the Display Network tab and then on the Display Keywords sub-tab.
