300 word descriptions not being picked up by 3rd party

Since we were told to have 300 word descriptions on our videos, they are not being picked up by Yahoo or AOL. I have had 3 videos go full distribution (all with 300 word descriptions) and none of them have been put on AOL or Yahoo. This cannot be a coincidence as I have never had a full distribution video not be shown on these channels. I also checked other videos with 300 words vs small descriptions and they aren't being picked up either.
Can you clarify why this is happening @mario
