I know it's going to be a matter of time when this could be an issue. For instance, somebody that has uploaded a video and the content has changed years later. Maybe they have a business and moved, yet the existing video has the old location address...an employee/spokesperson has moved on...etc.
I'd prefer not to lose my current rankings and view count on a few videos, but quality needs improvement. Aside from deleting the entire video what options do I have thesedays?
i know you can edit the content in the 'more info' box; however, i you may lose ranking based on the keyword for which that text is optimized; instead of changing it just add any changes as an update in the text box with new links.
