Okay everyone says you have to pick the right keywords and such... how do you know what your keywords are?? I'm NOT asking how to find good keywords... I'm asking how youtube determines which of the words in your description/title/tags are the keywords... example... the nike air Jordan lx2999 is the best shoes of 2016. How/does youtube know that I want my keyword to be "best shoes of 2016" and NOT "the nike air" or "the nike air Jordan" or even in reverse.... "nike air Jordan" would possibly be a good keyword... how does youtube know if I want it as my keyword or I don't? TTLR... How do I specify my keywords.... Like where do I specify what my keywords, the words I place into the description/title/tags, are for my video?
