I tried different AdSense ad unit combination and position and decided to share my exprience. Now my CTR is almost 3 time greater then before I tried to optimize AdSense CTR.
My first AdSense combination
AdSense units - in first AdSense combination one Banner (468 x 60) (text & image/rich media ads) AdSense ad unit was placed on top of blog, below blog title and menu and above post title. Second AdSense unit was Leaderboard (728 x 90) (text & image/rich media ads) in the footer of the blog.Duration of this AdSense combination: 12 months
Click through ratio - CTR: 0.10%
Second AdSense combination
In this combination Leaderboard (728 x 90) (text & image/rich media ads) was replaced with Medium Rectangle (300 x 250) (text & image/rich media ads) ad unit. Medium Rectangle (300 x 250) is one of recommended AdSense ad formats. Another Medium Rectangle (300 x 250) (text & image/rich media ads) ad unit was added after blogger post (below comments). Leaderboard (728 x 90) (text & image/rich media ads) is in the footer of the blog as in my first AdSense combination.Duration of this AdSense combination: 8 months
Click through ratio - CTR: 0.28%
