The most exciting AdWords feature to be rolled out in some time is Remarketing for Search Ads. The "audiences" for this feature work exactly as they do with classic remarketing; the difference is that the ads may now appear in Google search engine results pages, triggered by conventional keyword bidding. "Behavioral targeting" has acquired a bit of a creepy reputation, seemingly overnight. It's not clear that it's inherently over the line.
Internet users in the U.S. may have already noticed a slightly changed layout in Google search results. While the change will go unnoticed by tablet users who are familiar with the layout (since last year), desktop users getting the new layout now may well miss altogether what the change really is. In an attempt to create a consistent search experience across the wide variety of devices and screen sizes used today, Google changed the design of its main search results page, making it cleaner, simpler and with a bit more breathing room.
