Google AdWords has a "card" on the new AdWords interface named "searches card" that aims at showing advertisers rising search trends. Specifically you can see which words your customers are using to search for you on Google.com, and refine your keywords for better performance, Google said.

These searches card are available on the overview page in the new Google AdWords user interface, after you click on a search ad campaign. More details are in this help document.
