There are a ton of different ways to market your content/brand or even your live streams.
- Facebook adverting - You can pay to advertise on facebook
- Good ole' giveaways - This is an old technique but still proves really valuable. Buy an item for a giveaway and have subs like and share your video for a shot to win a certain prize (Check with your state about giveaways first)
- Word of mouth - if you have good content,then word will travel pretty fast
- Have your own website - You can create your own website to help with SEO searches
I will add to this. This is mainly just a content holder.
