Number of Adsense Elements On One Page

[aj113]

Hi All
I am struggling to find the information I need from Google:

Does anyone know the number of Content ads, text ads, referrals, Google search boxes and You Tube ads you are allowed on one page?

Also, can anyone comment on the effectiveness of You Tube ads? Are they a useful addition, or does the load time work against you in terms of losing visitors who may otherwise have stayed awhile?

Very low CTR and accordingly revenue. It seems that the ads are targeted but the videos are not resulting in fewer plays.

The numbers are defined in the Program Policies under "Ad Placement"
