Backlink Ranking Service?

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.

Are you familiar with SEO for Google? It's similar for Youtube. Additionally, you could try ranking videos on Google if you make the videos unique.

For these sites you can use sape and PBNs they will help you rank your videos fast. Or you can try Web 2.0s, you will find tons of sellers in BHW BST section.

Build some quality Links & Embed as much as Possible. Your title & tags should be well optimized.

To rank Video on goolge... This will help you.. But you need good Setup with GSA

Youtube Video >> T1 (web2.0 with Unique spun content, Image , Embedding your youtube video, On page SEO and Link pointing to your Video)
T1>>T2(all do follow links and contextual links from GSA)
T2>>T3(all do follow links and contextual links from GSA)
T3>>T4(Spam Links)

Thanks for the feedback everyone. I know youtube had cracked down on spammy links but I guess for T3 and T4 they're OK to use after web2.0 and PBNs.
