Frequently asked
Should I show code in the thumbnail?
Almost never as the hero — it's unreadable at thumb size. Use a logo, a stylized icon, or a final-product screenshot, and reserve actual code for the video itself.
How do I make a tutorial thumbnail click?
Logo + outcome promise ('REACT IN 15 MIN'), a face reacting, and a clean colored background. The viewer should see the value in 0.5 seconds.
What about for niche topics like Rust or Elixir?
Lean on the language mascot or logo. Smaller-language audiences are loyal — a recognizable mascot in your thumbnail signals 'this is for us'.
Are screenshots of finished apps a good hook?
Yes for build-alongs. A polished UI screenshot ('I built X in a weekend') is one of the most reliable formats in the dev niche.
