I have vieo objects in my video pages and roperty list looks like as follows

name
description
duration
url
thumbnailURL
author
url
contentURL
embedURL
playertype
uploadDate
height
width
isfamilyfriendly

what I would like to ask here is; I have video title in the url property but thumbnail and video source urls are unique values, should they have video title in their urls.

Secondly, is keywords property important about seo, because I do not have them.
