So at the beginning of the year I started a collaboration project on my channel with a group of other people. We each have a day of the week that we are responsible for posting a new video. We've been pretty consistent. There has been a few days here and there that were missed, but for the most part we are putting out pretty decent videos (mainly vlogs and comedy sketches) etc. I've been buying views to boost videos. I've done a few paid FB ads from our fanpage, and used YT ads but I'm having trouble ranking our videos. I also post all over social media - tumblr, twitter, etc. I have not used any backlinking service yet because there are so many of them and it's difficult to determine which services are effective. Can anyone recommend one that is good for youtube channels and videos? I feel like we have been working really hard and putting out some good content but I would like to get some more visibility.
