Google announced that they have launched a new default ad unit style that works better across all devices, mobile to desktop.
The changes include:
- A new default color palette of blue and grey, making the ads easier to read for the user
- An updated our default font to Roboto, designed for easier readability on mobile devices as well as desktop.
- They aligned the text ad font with the web font they use on our Android OS.
- Improved the call-to-action button by making the tap target size and position more user-friendly across devices
Here is one sample ad but you can see more over here.
