Don't forget to change titles to your videos that you've uploaded in August and current month is September. ( I think you get me what I mean, my English is so bad)
Description (IMPORTANT)
Make sure your description is related to your video. Be friendly in your description. Show people that you know what you doing. Don't be like this" *DOWNLOAD NOW* : your fileice link. Be cool.. explain them.. even give them (virus scan) will boost your downloads for sure. Don't put SHITLOADS of useless EXTRA TAGS that are not related to your video like "PAYPAL HACK, ALERTPAY GENERATOR" RUNESCAPE MONEY HACK and shits like that. Don't add tags like that.
TAGS
Add 5-6 maximum 10 tags related to your Title/Video. For example if you have video for Football Manager Keygen 2013 Then your tags should be like this: "football manager keygen 2013 key keygenerator"

Voice I. II.
If you use your voice in your video then you'll boost your earnings for %7-8 more for sure. Using voice making people believe you more. If you use Notepad/Word looks unprofessional and people will just leave your video.
