how Important Is video SEO for ranking a YouTube video?

Ranking depends on your channel, CTR and retention mostly.

I see young channel grow quickly with yt seo and good video content like Dan Koe, Steve Thompson and more younger channels. But most of you not go on yt to reach your target niche, you want go viral which means a lot of useless views and leads, leads who not buy from you......

Although SEO titles and descriptions help YouTube understand your video better, the long-term success of a video still fundamentally depends on quality content and a high viewer retention rate
