How to put more tah 3 ads on page

I have a website on which I have very very long pages.
and on it I can put only 3 adsense ads for content.
I want to put more ads
Please advice what I can do to put more ads on it.
Sample page of my website http://www.gemstones-guide.com/Beryl-Emerald-Aquamarine.html

 

You can put 3 image/rich media ads and 3 link ads units. If you try to add more, Google will automatically disable extra units.
If you have longer pages, you may want to try other ad networks like Chitika.

 

You can actually put 3units image/text ads + 3 link ads =6 units ads. It shall be more than enough

 

yes, the rule is 3 + 3, if you want to add more and you are looking at a trick such as using iframe, you'd better off closing your adsense account yourself.

 

seem can not do it

 

using more than 3 units of ads is not ethical dude. so try to avoid it. Remember that if you are banned from Google Adsense then it a huge problem to create another account.
thanks

 

You could put ads in iFrames and that way get around it but its not recommended 

 

This guy is absolutely right. You can make a page with only adsense, like "ads.html"... and wherever you need you adsense just put the code as:

<iframe src="ads.html" width="ADSENSE_WIDTH" height="ADSENSE_HEIGHT" ></iframe>

Code (markup):

replace the "ads.html" with any link you want to include...
