There are loads of threads of people asking how to keep your videos alive having looked at med-high comp niches this is what i have found out. The first three are the basics most people know. 1. Use private IPs this is a given. 2. Use phone numbers - i buy mine off ebay really cheap UK people have the biggest advantage with this. 3. Upload a profile picture and a cover picture, also use a video introduction. The methods below are the ones i believe help keep your videos up longer. 4. Upload tutorials of basic stuff "how to render a video for youtube" or upload montages of gameplay "bf4 headshots" For some reason this makes YouTube believe your account is genuine. 4b. If you have a multiniche site with niches with low search traffic add them to your accounts 2-3 of these and 1 video which has a medium to high search rate your uploads should look like this. random video low keyword video -ppd random video random video low keyword random video - ppd random video random video med-high keyword video - ppd random video random video. 5. keywords spamming in the description gets your video taken down, if you don't know what i mean something like minecraft as the niche and in the description you have loads of long tail keywords. 6. words like crack and hack in the title get taken down alot faster so dont use these if you can. Thats it really.
