I know having likes is important but I was wondering who do they actually do to a video if anything?

In theory I think they do nothing more then alert people if you video is worth watching in that way a lot of dislikes or likes can both be triggering to watch your video in some way for a person.
I believe it effects your search rank as well... i dont know the actual algorithm but i think they take into account viewer interactions as well as watch time.
They count towards video engagement (likes, dislikes, shares, comments all count towards this) videos with high engagement get ranked higher in search as well as showing up in the side bar 
Ok thanks.They count towards video engagement (likes, dislikes, shares, comments all count towards this) videos with high engagement get ranked higher in search as well as showing up in the side bar
