Recently I've read many good things about social signals.Many people say that they can help a lot in ranking youtube videos.So I decided to try it myself. First video had 7.5k HR views from BB.It was in 4th page of youtube for low comp keyword. Second video was in 4th page too with 7.4k HR views from same service. Third video - 9th page with 5k HR (same service). I gave 200 retweets to every video along with 40 fb shares.Next morning (about 12 hours have passed since I started boosting them) I open 7th page and see that first two videos are there.Third one jumped from 9th to 10th page. So I was wondering maybe this is some kind of new update from youtube, because in my opinion 7.5k HR 150 likes 10 comments and social signals should be enough to rank at least to 2nd page for 22k exact monthly searches and 12k results keyword ? Update:Added 40 more facebook shares to one of my video to make sure.And yes...After few hours it went down again.From 7th to 10 th page.Seems that social signals are worse than dislikes.Of course you can use social signals go down from first page to second or something like that if you need to.I guess that 10$ I spent on those videos went to s**thole... So my advice for people who want their videos to rank higher. DO NOT USE SOCIAL SIGNALS FOR YOUTUBE VIDEOS. Thank you!
