I think they are treated mostly the same by SEO, but seem to be ranked high on YouTube before the event starts, and then the comments and watch time really drive up rankings. A little update, my two biggest videos using this have over 100k views.this is really good! I never thought of doing this, or had any idea that live streams were ranked higher in seo i going to try this!
Wait... Isn't spamming loads of tags in your description against the TOS and can get you banned?
This teaches me nothing on how to boost my views on my videos through SEO, but only the livestreams themselves. I don't mean to be negative but this could get people banned...
