How to Create a Promotional Banner for Your Online Store for Free
Practical guide for creating high-converting promotional banners for Shopee, Mercado Livre, and Instagram without a designer or Photoshop.
What makes a promotional banner convert
- Clear visual hierarchy: offer > product > CTA.
- High contrast between text and background.
- Visible urgency: discount percentage in highlight.
- Actionable CTA: 'Buy now', 'Last units', 'Free shipping today'.
- Product in focus with clean background.
Banner sizes by platform
- Shopee store banner: 1200×400 px.
- Mercado Livre banner: 1200×600 px.
- Instagram post: 1080×1080 px (square) or 1080×1350 px (portrait).
- Instagram Stories/Reels: 1080×1920 px.
- YouTube channel: 2560×1440 px.
Practical tip: Use a background color consistent with your store's identity. Banners that follow the brand's color palette generate more recognition and trust over time.
