Can you display an identical ad block twice on the same page?

I've seen a website that displays an identical AdSense block twice on the same page. It means pasting javascript code twice. Is this allowed?

If not, is this only for premier account holder?

I don't think your impression counts will be counted double but does anyone know if it is effective.

 

Yes,

You can have 3 adsense for content units per web page, doesn't matter what size. So yes, you could have 3 768x60 units one page. Hope this helps.

 

Thanks ssandecki. I guess the more you have, providing tastefully blended, the more chance of them getting clicked.

 

Yes & No, having to many can drive down your CTR and your earnings. Beware of the smart pricing troll, hes out there lurking

 

Yes, you can do that.

 

You can have more then 3 .
3 Text-Image ads
2 search boxes
3 link units ads
One link for each referral of Google products

Enjoy, but placing all those together on one page will make it and ad farm .

try to keep the first ad that you can see on the code visible because it will have the best ads .

 

Yes. You can do this.

 

Good point about CTR ssandecki. Don't know what you are referring about smart pricing troll though Obviously, I'm new to this.
