Darren, does this javascript work for blogger?

I get the following message while editing my template source.

Your template could not be parsed as it is not well-formed. Please make sure all XML elements are closed properly.
XML error message: Open quote is expected for attribute “{1}” associated with an element type “type”.

thanks.

This is really great. I’m going to test my site to see which color format works best. I’m sure that I will find out if it’s better for my ads to stand out a little or blend in completely…

It did get kinda mangled didn't it? I should have noticed when I posted. I've pasted it all in a text file for you, and put it up at one of my sites. Hopefully, that's OK. http://www.digital-tv-converter.info/ad.txt

Aaron,

Most of the HTML you put in your comment was removed. I’m having problems getting the AdSense code to rotate too.

@ HAK & Alex:

I had the same problem with the } else { showing and the ad not rotating, but I figured it out this morning.

If you leave out the on your ads, and just put in what’s between (and including) the “” then no closing , it works fine.
EX:

var random_number = Math.random();
if (random_number < .5){
//your first ad unit code goes here
} else {
//your second ad unit code goes here
}

Good luck, and thanks for sharing Darren!!

I’m afraid. Is it against adsense TOS?

Good point made with the article. Is there a way to target specific ads? Honestly, I have an information site about Trojan Condoms but I get ads that are half for virus trojan removal… I use Adware and am new to this. Any suggestions?

Excellent! Can’t say much more than that, very practical and useful. Will put into effect immediately.

Very Good post Darren. I will use this to test what of my ads is better for me. When I get some clicks :(

Darren,

First of all, thanks so much for doing this. I’d love to see you put up more posts on coding.

Also, thanks for focusing on Javascript, which can be used by Typepad bloggers like me, rather than PHP.

BTW, I can’t see any ‘bolded” lines in the code in FireFox.

Finally, I’m looking for a way to rotate Amazon ads. I tried dropping them in using this approach, but it didn’t work. Anyone have any ideas?

That is possibly the most useful thing I’ve read in a very long time. Thanks Darren!

Wow that’s great advice, I’ve manually tested a few different setups so this will definitely help a lot.

Interesting concept and will definitely give it a go as soon as I fix the feedburner issues I have with my new blog.

Fighting with Cpanel etc. Newbie here.

Norm – I don’t use AdSense on this blog. I do use it on my other ones though.

Check out this video on why it doesn’t work at ProBlogger.

Awesome idea, this is definitely something that I will try in the next few weeks!

Thank you Darren…Love the adsense series you are writing. I haven’t yet implemented all the changes you mentioned…I will be doing that next week…This series is a valuable ‘ad sense book’.

If you have the “Who Sees Ads” WordPress Plugin (and you should, it’s easily the most useful plugin I have), it’s easy to set up an A/B comparison (or just randomize ads) with the “ROTATE AD” feature. You can even combine this with some of Who Sees Ads other features, so that for example you could keep an ad static if it’s someone coming from a search engine. but rotate it if it’s a regular visitor.
