Make sure you share your video immediately after uploading it. People like to have the most recent info out there & these days 1 week is considered old. Also include extras...music, bloopers, credits, etc. And be sure you've linked to it from your site & social media accts. Also, go from another acct. & comment on the video/channel. These things would all be secondary to your video name & tags. The name & tags are really what makes or breaks the video (besides quality content), these suggestions are just little tweaks that could help a bit. Good luck!
