My sig video is at 27% search and 18% suggested video results. Unfortunately 39% is unknown direct, which doesn't help me identify the traffic source. Overall, my videos together are at ~21%.
Unfortunately, in some cases it won't matter how good your SEO is. Some keywords are just so incredibly over saturated with other content that you can't compete. Additionally, things like total views, comments, and likes are taken into account to determine ranking as well, and unless you have a huge following, there's not much you can do in that regard.
Instead, you can research the potential keywords you will may choose. Or hell, even craft a video around a title that you think will rank well.
