Design tips for 320×48 ads
- Same rules as 320×50: one object per photo, plain background, short prices.
- Keep the file under 150 KB and export it at exactly 320×48; design at 640×96 so it stays sharp on phones.
- Show a price - across all sizes, ads with prices got more clicks than the same ads without.
