YouTube Changing Algorithm

Announcement yesterday from YouTube says they are changing the way they push videos to the top of search results. With the many SEO and search algorithm changes Google has been making recently why should their sub-companies be any different? In the past, Google pushed videos to the top of search results based on “Total Views” but now YouTube announced they will now monitor “Total Viewing Time” to push videos up. This is interesting because it could be the difference in a .30 video being seen 100K times and a 8 minute video being seen 15K. Since the 8-minute video was so much longer is it really a benefit for it to be the first in the search results?
