My suggestion is to use an automation program. As long as you don't over spam and violate Twitters rules. Twitter is a very noisy platform and making 24-50 tweets a day is acceptable, but you've got to be a machine to be able to manually tweet that much per day. I suggest for non programmers to use Buffer. The free version allows you to queue up to 10 tweets at a time and have them posted at whatever time you want.
Other tips:
1. Use hashtags properly
2. Don't just post your content, retweet other people's stuff. I also post a lot of motivational quotes with hashtags like #MotivationMonday #FunFactFriday
3. Pin your latest video that you want to promote the most
4. Understand Twitter doesn't like Youtube links on mobile and that most twitter users are on their phone. So it's better to upload an image of your thumbnail, or a short animated Gif of your video and then put a link to your video
5. Thank as much of your twitter followers and those who retweet you as much as possible. Stand out from the crowd and video message them. They'll remember you! I admit sometimes I get lazy at this especially when you're getting so much followers daily. But at the early stages, it's worth your time
6. Add people to Twitter's built in lists system. This makes people feel special, especially those who retweet you, mentioned you, or interacts with your tweets. Put them in seperate lists.
7. Use IFTT and create a recipe that automatically adds people to a list when they tweet a certain hashtag. This will make your account easily found by others
With these tips alone, I've built a follower base of over 2600 in 3 months and get several hundred views from twitter monthly. It's not a lot compared to how much Reddit helps me, but it's still worth it as I barley have to do anything as my twitter tweets 24/7 automatically.
