Google is making it easier for website owners to integrate AdSense units with their sites thanks to the re-introduction of Ad styles, which enable them to quickly edit or create a new color scheme for ads and then apply it to any and all units they use. "With ad styles, you can create customized combinations of colors, fonts, and corner styles and then easily apply these to the ad units and search engines across your site," Jessica Hummel, Google AdSense Engineering,
wrote.
The main advantage of ad styles is that they can be applied to any number of ad units with ease.
This way, you can change all of the ads on your site to match a new design with only a couple of steps as opposed to manually editing the colors and options of each unit.
In turn, this should make it easier to experiment with different looking units, knowing that you can switch back at any time.
