Google has added to the new version of the AdWords interface a Searches card that shows at a glance the search terms most often being used in searches that land users on your site.

It looks like this:

Google suggests that the card be used as an alert mechanism to identify surging, relevant search terms so you can react by adding keywords or ad groups.

Or to identify irrelevant searches quickly so negative keywords can be added to eliminate clickthroughs for which you're paying but receiving no value.

This looks like a win-win for Google and marketers (if you're happy with the New Experience).
