I was using Twitter just posting(and other stuff) about my Youtube channel and to check out my new video on the Twitter feed 1/2 times per week for a while and i did not get any videos views or subscribers and i was following alot of people and getting lots of followers nearly everyday and i hope they would go on my Twitter and check out my Youtube channel/new video but unfortunately it was not the case, they did not go on my Twitter and check out my channel/new video.
Untill it all changed when i found a a very good(best) way(on Twitter) to get a lots of video views and subscribers over a month and a bt ago.
I have found DM people on Twitter telling them to check out your Youtube or new video it is the BEST WAY to get views/subscribers especailly when you are small Youtuber or just starting out on Youtube, it is working out very good for me so far, now i am getting a lot more videos views and subscribers than ever before.
1st you have to set up a Auto DM(or multiple DM's) on a site like Justunfollow.com each time you get a new follower on Twitter they will get your auto DM saying thanks for following and telling them to check out your Youtube channel or video.
But you have to follow(a least +200/800 people at a time) lots of people(followers of Small/Big Youtubers and people who likes Youtube) to get lots of followers after you set up a auto DM on Justunfollow.com in order for it work and to get lots more video views and subscribers to your Youtube channel!
After over a month since i started doing DM people telling them to check out my Youtube(or video in another DM) on Twitter I have a lot more video views now than over a month and a bit ago and i was getting 1/2 MAX subs per month and was not getting any video views for a very long time, i use to have only about 26/28 subscribers over a month and a bit ago and now i have 98(only 2 till i get to 100

) subscribers on Youtube and most of them are active subs and i checked on Youtube analytics in the last month i have gained over 70/75 subscribers.
My Youtube channel is growing a lot more now than over a month and a bit ago i am getting credit for my videos now which it is great!
And it is NOTHING like Sub4sub because if you do Sub4sub all you get is dead Subscribers and is complete garbage.
And make sure you post other stuff on Twitter, don't use your Twitter just to promote your Youtube channel/new video.
