Tags are a set of keywords that can be assigned to a video or set of videos. For example, all of your videos with fish might be assigned a tag of 'fish'. Multiple tags can be added to a video. Tags facilitate searching through your media library and can also be used when creating playlists.
If you properly tag your videos, you will be able to search through your video library in a much easier pace and furthermore similar content will be served to your viewer base as related videos will be served depending on these tags.
We suggest that you tag your videos appropriately on any of the add video forms explained above, but if for some reason you need to change any tag, you can do this on the edit video screen which will be explained in a later chapter.
