Google announced you can now control the color of the link text when a user hovers over that link. You know, when you mouse over a hyperlink, the color of the link on mouse over is now controllable by you, for the AdSense ads.
As we continue to improve and launch new features, we're always interested in hearing your ideas and feedback. Many of you have shared that you want to be able to change the title color of ads when a user moves their mouse over the title link. After a period of testing, we found that this feature resulted in higher earnings for publishers while also increasing user and advertiser value. We are pleased to announce today that we have updated all text ads with this change.
Google has tested this a few months back and decided to enable it for publishers. Give it a try and let us know if it works for you.
