YouTube changes search to rank based on how long users watch videos, not clicks

Source: The Verge
op:
The youtube music top 100 videos category works with a combination of algorithms that take into account clickthru and referral links along with views, comments and likes. Now it also includes time watched and time spent looking through related videos. Ganganm Style entered the top 100 at #15 on 2012/7/31 and dropped out on 2012/10/16. The changes went live on the week of 2012/10/12.

Here's the performance history on YT 100

What does this mean for Gangnam Style? People are not watching the whole video. This past week at least, most people that did watch it saw less than half of it. That's less than a minute fifteen seconds. While this doesn't affect total view counts, it lessens the search rankings.
What does this mean for your oppas and unnies? it'll be almost impossible to get them on the front page and reach a wider mainstream audience through the sheer force of your refresh views unless the track is actually popular, and view bots will have to find another way.

What is the new rules on Billboard?

The same youtube that invited Psy to their headquarter... oh well

Date: 2012-10-16 09:56 am (UTC)Also OP, I'm pretty sure reason that PSY being dropped is actually a glitch 'cause his likes and comments keep continuing to grow, so I doubt so many of the views would be click throughs that it would completely drop out of top 100. Also in order your view to register you have to view most of the video. And Gangnam Style got about 60 million times during last week. So him being dropped off the chart is total BS on behalf of youtube.
