The question makes me think you must be running a campaign on the Display Network. If that is the case, just click on the Display Network tab in the interface and the select Placements. Note that there is some delay of 2-3 days before you'll see the required stats.

Actually I'm using text ads. Is there a way for me to find out the CLR ratio on each page. I have different configurations of google ads on different pages and I would like to find out which configurations work the best but to do this I need to know which pages are getting the most clicks.
