Mobile is where most viewers are
YouTube's mobile layout is a single-column feed with larger thumbnails and more aggressive title truncation. A title that reads perfectly on desktop might get cut off after just 40 characters on mobile.
Use the Mobile toggle in the preview tool to see exactly how your video card will appear on a phone. Front-load your most important words in the title.
