With so many options to put backlinks to your content, you need to choose carefully where you put them, and YouTube is a very good option, because it accounts for about 40% of all mobile traffic.
I believe diversification can be a strategy for online content creators who want to make use of as many platforms, social media, etc. as possible. However, time limitations can prevent the implementation of this strategy.
Another strategy could be to build a big community of followers on one or maybe two platforms for content promotion. Although this strategy also requires a certain amount of time, it can be more time-efficient than the first strategy.
All in all, YouTube can prove to be ideal to implement the second strategy.
