Before I start I just want to say that this is information that I've tested myself. I use to make 900$ per day with YouTube on average posting 2000-3000 comments per day so I am very familiar with YouTube. I had a freelancer make me a program which comments YouTube videos by signing in and out of accounts and posting 2 comments with each account. I hired an indian here on BHW and he made me 100 accounts for 12$. In that week with my program I made about 3200$ and got SUPER screwed by YouTube. ALL my accounts were banned and so I got a new batch of accounts and they post comments , but my comments get marked as spam VERY soon and I only make about 150$ per day now. Results from my testing: -Once you are marked as "spammy" by YouTube , there's no going back. Keep in mind youtube is owned by Google , the same company which made apps like Google Earth and the incredible search engine they have. -Proxies , VPN's , different accounts and different browsers won't work. YouTube tracks EVERYTHING , mac address , ip adress , similarity in comments , accounts , track you using cookies and more which I probably don't even know about. Solution: Sorry to say but I've tried everything. Ive tried starting from scratch with private proxies only I had access to, and with accounts I created myself and completely revamping my comments and even bought a new domain. It seems as if there is no solution. I can't even create accounts with any different proxies I buy because YouTube recognizes proxies somehow and won't let me access the registration page. ( Try it yourself I'm not kidding) As for posting tips: - make your comments look realistic - don't make them too long - don't generalize them to a big niche , take the extra time to change sets of comments manually if your using a program. EG" instead of posting in the entertainment niche , try post for oprah winfrey and dr phil videos. - keep it simple! EDIT: I THINK I MAY HAVE A GOOD SOLUTION! When people were clueless about proxies with craigslist what did they do?WARRRRDRIVING. I'm getting my first vehicle since im now of legal age to drive(09 escalade) registered to my name on tuesday and so I will report back with my earnings and results. Will be changing domains , comments , accounts and even niche.
