You are allowed a maximum of 3 ad units combined with 3 link units in a single page. Hope that answers your question.
A total of 6 Ads. Be sure thought that you place them in the right location because there are rules on placing the Ads and if you do not know where you might get your account shut down so be careful and read the AdSense TOS.
I think we can display 3 ad units, 3 link ads and up to 15 google referral ads, correct me if I am wrong.
According to the Adsense Terms of Service: 3 ad units, 3 link units, 2 search and 3 referral units (although the referral program is ending the last week of August). https://www.google.com/adsense/support/bin/answer.py?hl=en&answer=48182
On any given page, you're welcome to place up to: - Three standard ad units - Three link units - Two search boxes - Three referral ad units - One video unit
3 ad boxes but beware the fact that the more the ad boxes contain and the less the strength of the keyword you might actually do yourself more harm by having more ad units on the page. Lovely for Google but might not be so good for you.
