Most Google Adsense publishers match the ad border color with the site background to remove the ad unit border and increase clicks to generate more money. The square edged border failed to blend with many web designs, and now I see an option to create rounded corner borders.
Login to your Google Adsense panel and find a new option of Corner Styles to optionally choose from one of 3 pre-designed corner styles
square corners (default)
slightly rounded corners
very rounded corners
It adds a new line of code to the generated Adsense code
google_ui_features = “rc:10”; for very rounded corners
google_ui_features = “rc:6”; for slightly rounded corners
google_ui_features = “rc:0”; square corners
Now I am sure people will find more unique ways to incorporate borders in their ad units to generate more clicks. Try the new borders and check out if it brings in more clicks for your site.
