I will lay out 10 points on being consistent: 
 

1. - Having interviews with other subject matter experts helped me gain more traffic and subscribers
2. - Most of the hard work went into promotions than creation which led more people to explore the videos by YouTube Search
3. - YouTube Tags, Keyword research, and title helped me rank on YouTube for competitive keywords and gain more views
4. - Giveaways for people subscribing (A small growth hack for increasing numbers)
5. - Small 3-4 minute videos from long interviews made them easily consumable, hence good retention leading to YouTube recommending more of my content
6. - Organizing playlists to increase watch hours
7.  Will be honest: I also hired a famous Indian YouTube consultant to help me get more subs, eventually helping in getting my keywords right with thumbnails (I never hesitate to take help)
8. Facebook Groups: One of my biggest playgrounds. This became my biggest social media traffic source as our LIVE Interviews were conducted here.
9. - Shoutout from my friends (OTHER PEOPLE’S NETWORK) helped me get attention from different audience groups and sources
10. - My Email list contributed to my views + subs as well.
    
    overall, a game that I will begin again, and hence aiming to take it to 1000+ Subscribers very soon.
