Google announced new mobile display formats and tools for advertisers today, making it easier to build campaigns in a multi-screen world.
Among the new offerings will be mobile lightbox engagement ads, which "dynamically resize to fit any screen size." Also, TrueView advertisements, the skippable video format originally designed for game apps, will be available across Google's AdMob network.
Other new formats include an anchor ad that sits at the bottom of the screen of a user's mobile device, staying there unless the user dismisses it. There also is a new glossy, magazine-style text ad format.
Google described the new styles as "big brand ads, built for mobile and resized for every screen." The company is offering an auto-resizing tool for the Google Display Network, as well as improved Flash-to-HTML5 conversion tools.
It said the changes would become available over the coming months but did not specify which services would be released first.
