You are right that videos need more than just views to be popular. But what i've noticed with my videos at least...when i first upload them...and place lots of views on them...say 20k in a day using tube increaser.....I gets lots of hits and conversions......but after about a week...everything dies down. So i'm assuming that the recently uploaded query is what most users are using........My video is not of the "viral" type...but it does get conversions when people see it.
