Youtube Tags and Description Question !

[DemolitionX]

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?

This is something I've always wondered about myself. I never found a definite answer so I just put all variations of the tag, it takes more time and uses more of the tags up but then I feel like am on the safe side.

As for your last question. I am almost certain adding extra tags in the description makes no difference. I've tried putting them in the description before and I am pretty sure it didn't help with the video ranking. They only do it so they can add even more tags than YT allows them to

it used to work that way , Repeating keywords in description used to make the video rank higher . They patched that now seems like description doesn't matter much anymore.
