Hey guys, can anyone provide me with a source explaining youtube tags, in terms of what is unnecessary and what isnt. For example, if i have the tag "win free iphone 5 now", is it necessary to put the tags "win free iphone 5" or "free iphone 5 now"? Or does the single tag "win free iphone 5 now" also cover all variations of it? I have always wondered about this and have never found a proper explanation.... ALSO: Is there any merit or point in putting extra tags in the youtube description? Every now and then I will come across a video which has "IGNORE" and then a huge load of tags related to the video in the description. is this useful or pointless?
