Google AdSense now allows you to change the title color of ads when a user moves their mouse over the title link, in a October 28 blog post, Stephen Yuan, AdSense Engineering, announced that starting today that we have updated all text ads with this change.
"As you can imagine, there are numerous combinations of link and background color across the ad units on all publisher pages. After extensive testing, we have found that the color of the change itself can make a big difference: the wrong shade can even be detrimental to clickthrough rate (CTR)," Yuan said.
Adding, "To determine the color that the title link will change to when a user places their mouse cursor over it, we'll take your chosen title color and find a nearly complementary color on the color wheel. For example, a blue title would change to red. These colors outperformed all the others we tested, explains Yuan.
He promised to continue studying the effects of color on CTR and ad performance to bring you more enhancements in the future.
