I have few minutes of free time, so I decided to show you simple php script, how to change colors of the ad or type of ad unit for every page impression. With this we can achieve that our ads are more interesting for visitors (like on DP at the right-top). Here is the code. <?php // fill the array $code with unlimited different ad codes // instead of text, copy the full adsense code, the one you get in adsense setup $code[] = "adsense code #1"; $code[] = "adsense code #2"; $code[] = "adsense code #3"; $code[] = "adsense code #4"; $code[] = "adsense code #5"; // output one of the codes - random echo $code[ rand(0,count($code) - 1) ]; ?> PHP: Hope this code will be useful for someone, who doesn't know allot about php programming. If you have anything to ask, fell free... I have today day off and have lots of time. Have a nice weekend.
