Well its pretty much all in the title - I tried generating a variable with the value of a random number between 0 and 1, and then using IF (the variable) is equal to or more than 0.5, display (first ad), ELSE (second ad)

This didn't work.

I just want to have my ads showing 50% of the time, and someone elses ads showing 50% of the time - how?

Thanks in advance

Danny I think I would have tried it the same way you did. Do you want to post the code?

Any chance you can use a server-side rotator? This way you can also expand to add a third, fourth or ... number of options in rotation and manage it without having to change code later.

I use integers and find it works better (in your case, 1 and 2).

www.libreriapandevida.com (the ad rotator on the top right...steal the code and modify to your heart's content.)

Thanks for the help guys - particularly ADAM

Sorry, but I realised that I actually dont get it after all lol

sorry to bother you again, but I don't understand why this isn't working. My first thought was to try this:

(By the way, I'm really a bit clueless when it comes to JavaScript, so bear with me )

<script type="text/javascript">

var r=Math.random()

if (r>0.5) 

    {


<script type="text/javascript"><!--
google_ad_client = "pub-1472271703469017";
google_ad_width = 160;
google_ad_height = 600;
google_ad_format = "160x600_as";
google_ad_type = "text_image";
google_ad_channel = "";
google_color_border = "FFFFCC";
google_color_bg = "FFFFCC";
google_color_link = "6F3C1B";
google_color_text = "6F3C1B";
google_color_url = "6F3C1B";
//-->
</script>
<script type="text/javascript"
  src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>

    }

else

    {

<script type="text/javascript"><!--
google_ad_client = "pub-8905391473999593";
google_ad_width = 160;
google_ad_height = 600;
google_ad_format = "160x600_as";
google_ad_type = "text_image";
google_ad_channel = "";
google_color_border = "FFFFCC";
google_color_bg = "FFFFCC";
google_color_link = "6F3C1B";
google_color_text = "6F3C1B";
google_color_url = "6F3C1B";
//-->
</script>
<script type="text/javascript"
  src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>

    }

</script>

I did spot several possible flaws in this, including the inclusion of the script tags and the (")'s that should perhaps have been (')'s, but no matter which variation I use, I cant suss it.

Then I tried to change the publisher ID to a variable, and use:

 if (r>0.5) 

    {
var pubID = ***My Publisher ID***
    }

else

    {
var pubID = ***My Partners Publisher ID***
    }

Again - no luck.

So please - I am tearing my hair out over this one - does anybody have the solution?

Thanks very much

....... ok this is the way I would do it myself...

Wrap the google script inside a <div> tag with an id, then create a timer so that every lets say 5 mins it would then rewrite the innerHTML of that divider.

Of course I am unsure if it would work as I havn't tried it myself.

Also you should use whole numbers, so when you use the math.random() ability it will generate a whole number

Paramillar has the right idea...your major problem is that you're trying to include Javascript within Javascript. This can work, but you should be putting it in some sort of quotes or something along these lines:

var googleAd1 = '<script type="text/javascript"><!--\n';
googleAd1 += 'google_ad_client = "pub-8905391473999593";\n';
...

Paramillar: the problem with your method is that you'd have to hide the divs on the page, which means the ad code would load (as would ads) but they wouldn't show initially. This would be a violation of Google's ToS. Not a bad thought, though.


Angelosanto: if you wanted to try something along the lines of what Paramillar suggested, you could create a page containing nothing but the Google Adsense code and have it retrieved via AJAX. That's another option.

Thanks very much - I think I managed to figure out how to work it

Thats the good news. The bad news is, that most people I've spoken to seem to be of the opinion that it counts as violating adsense ToS.

Sooooo, after all that, I'm afraid I'm going to have to move this query over to the PHP section!

Sorry about that guys, and thanks for your support!
