Since I change my Adsense format, URL and text color, I really had a higher click through rate, and you, which Adsense format & color scheme will convert best for you? In my view there are three main rules to keep in mind: Don’t use borders. Color your AdSense’s units background the same as your website’s background. Adsense URL color the same as the text? Here, the format and color I use: Format: 300x250 Colors: Border: ffffff; Title: 0000CC; Background: FFFFFF; Text: 000000; URL: 008000 Note: I make the color of my menu header the same as the URL of my banners ads, and the title of my articles the same color as the title of my banner ads.
Blue links and with ads format size of 250 x250 is the best for me. Of course, the background color has to blending with our site's background.
try title in red! It stands out nicely! If red doesn't work for you, go for blue, as people expect links to be that colour
