several question about traffic for adsense site

i have some question about traffic from adsense site, i know if traffic from traffic exchange is prohibited for adsense TOS, and adsense really like traffic from search engine, my question

1. if my major traffic is from youtube because i made popular videos there and offcourse click conversion from youtube visitor who came to my site not from search engine, is this safe for adsense?

2. how about implement adsense in file hosting, if traffic redirected from my site to that file hosting, so no traffic from search engine

Thanks

 

Traffic from youtube is very safe.

 

traffic from sites which are capable of bringing traffic are safe.So dont worry.

 

YouTube is a very good medium to get traffic and G won't have any doubt about it and redirection is also fine.

 

from youtube usually safe , and pretty good traffic

 

Google usually knows where a traffic came from, they surely knows every tricks some people do just to have visitors and tricks. You don't have to worry much if you know you are not cheating.

 

That's shall be fine for adsense if the click is natural click
