The domain portion of your display URL for all ads appearing on Google's search results pages will begin appearing in all lowercase letters within the next week, Google announced yesterday. Standardizing the look of the URLs improved click-through rates, according to Google's Lisa Shieh.
Google will automatically change display URL domains to lowercase when your ad is served (e.g., Subdomain.Example.com/Subdirectory will show as subdomain.example.com/Subdirectory).
Google also announced the arrival of negative keyword lists to your account's Control Panel and Library. You can now more easily manage a group of negative keywords and associate the list with multiple search campaigns.
