YouTube is more likely to recommend videos with titles under 55 characters because they are less likely to get cut off.

People desire room for creativity Instead of titling a video: “Best way X on Y” Try: “How I X on Y”

This way you’re giving them a good starting point but they feel like they can tweak / innovate on it. This also enables them to take ownership of whatever workflow/system they come up with.
