Comments on: How to Randomize AdSense Ads with Javascript

So you want to show a different Ad Sense ad, depending on the situation?

For this, I would advise using PHP. The Javascript alternative above is good for a simple random selection of ads, but it’s not going to work as well when you have to interact with a database.

However, the same concept would apply. First, you want to make a variable that tells the script what type of ad to display.

For example, if the admin is viewing the page, the variable is set to 1. If the author is viewing the page, the variable is set to 2.

Then, use a switch statement to echo the proper Ad Sense code.

I am a non-techie. i happened to land on this interesting page.

I am struggling to put together a rotator for three adsense codes on a wordpress article directory I am planning for a long time- admin, author and referer.

Obviously the last two have to be picked up from a database.

Any help possible?

Sure. To do that, you should save the Math.random() value in a variable (like var prob). Then, include extra if/else statements and modify the percentages, kind of like this…

var prob = Math.random();
if (prob > 0.66) {
  //  First Ad Here
} else if (prob > 0.33) {
  //  Second Ad Here
} else if (prob > 0) {
  //  Third Ad Here
}

Greetings.

Is it possible to have more than 2 ads rotating?

Thanks in advance.

The biggest reason you’d want to do it is to test out a new type of ad.

For example, let’s say I wanted to see if text ads or an image ad worked better in my Skyscraper. I’d go into AdSense, create two ad units, give each an individual channel, and then randomly select which to show.

After a week, I could compare which performed better and see which would earn me more money. Likewise you could test different color schemes and themes.

but why would you rotate page specific ads like adsense? they are contextual ads, they dont need to be rotated.

I’ve seen something similar for randomizing the ad colors. It makes them dynamic enough to stick out and be interesting.
