I wanted to try and rank a few videos on youtube. I was going to create 2-3 similar videos on different accounts, and try different techniques to try and rank them. If they fail, oh well. My concern is, since Youtube is owned by Google, should I be a little more careful, since they'd pretty much know all three accounts are the same person? And also if I have my link in the description for my site, does anyone think if I use blackhat on the video and my site is in the description Google may notice that? Not necessarily penalize but connect the youtube account to my site and have it on file that they are connected?
