Design tips for 300×600 ads

  • Eight tiles of 142×137: square photos fit best.
  • Group related products (one collection, one colour) - the ad reads like a shop window.
  • Keep the file under 150 KB and export it at exactly 300×600; design at 600×1200 so it stays sharp on phones.
  • Show a price - across all sizes, ads with prices got more clicks than the same ads without.
