There is a lot of emphasis put into the idea that YouTube relates a lot on the title and description in order to know what to do with my videos and who to show them to. So, the question is, if I upload a video with a decent decsription that is say one paragraph, but later on am able to expand on that description to give even more information and decide to change it, what does YouTube do with my video then ? Does it re-analyze my video meta data each time I save it for any changes? And if so, how long can that take?
