Pro tips
- Keep on-image text under 5 words — it must read on a phone.
- Use one clear face and one focal object.
- Match your title, don't repeat it word for word.
Mistakes to avoid
- Tiny text that disappears on mobile.
- Uploading the wrong aspect ratio — Shorts and long-form need different sizes.
