Here's a very simple guide. if you created a blog and purpose is just for adsense, here's a simple way to increase ctr.. 1. Use a clean 2-column theme with a max of 3 color-combination... More color distracts visitor's attention... 2. Select a theme that has a post title with similar color to content.. 3. Use only one ad slot and that should always be under your title.. make sure to put gap between ad and title or a small word "advertisement". people who stumbled into sites with a lot of ads just leave... 4. Blend ads with text colors... here is an example of excellent blending... take a look at the ads between search results.. http://www.workabroad.ph/search.php/jobs+abroad/q/electrician/c/.. Google ad is almost unnoticeable.. 5. If you are running a blog, always put "google search" at the end of your article... Most people do the search after reading... here's an example: http://mosquitorepellent.info/2010/01/natural-mosquito-repellents/ - notice how clean this niche site is though it is a new site and has only 2 articles.. There's nothing to click except for ads and search field. 6. The concept of putting too much ad in one page is not applicable at all based on my long experience... Too many ads will only create annoyance and low CPC.... Good luck...
i think float a google ad images in the first of your topic on the left is very great way and put post image in the middle of the topic and at the end of the topic but large rectangle with blind background
