Like and dislike: how affect to video on YouTube?

Each video, i see likes and dislikes. Some has many likes and some has many dislikes. Like and dislike affect to the amount I get, don't them?

if a video has thousands of views, lots of engagement and plenty of shares, a lot of dislikes will not be the only factor used by YouTube to rank the video

I think Rebecca Black learned a lesson about YouTube. First, you need thick skin, and second, bad engagement can still turn into major views. That 53 million views number, by the way, isn’t nearly as many views as this video actually has, because it was pulled on its first go-round (probably from all the hate it generated). But someone tell me how a video that seemingly no one likes shot up to 53 million (and definitely more than that)? And even with over a million people hitting that dislike button, there’s still over 250,000 who like it. There are probably people who are liking it ironically on one side, and people are disliking it for fun on the other side. But you’re doing something “right” if this many people want to watch the video.
