Leave noteworthy comments on other peoples videos, make noteworthy stitches of theirs. Embrace remix culture, essentially. It only seems like an intractable problem to non power users of social media.
If those videos receive no views, then it means the concept of the stitch wasn't compelling. Practically speaking -- just do it over and over again until you find something that does work.
Some people have a knack for making content that goes viral, but for most folks, it's a muscle that needs to be learned through lots of practice, with a lot of early going seemingly bearing little fruit until the inflection point is reached.
