I Love YTtalk
After an upload, the suggested section is in flux for the first few hours. Yt runs countless A/B tests to determine which videos deliver the best viewer experience, and ultimately lock in suggested spots to them. If you can't get in within the first day or so, chances are you won't get in there later.
The higher your video's initial view velocity, and the better the internal stats, the greater that video has a chance to end up on suggested of a bigger channel.
The smarter Yt gets, the less that tags and all that have relevance. Otherwise for every "lava challenge" video, there would be another 10 lava challenge on the right sidebar, which may not be what viewers actually want. The suggested is tailored to groups of audiences and individuals, so what's seen on there is varied between demographics and individual viewing patterns.
