Character Limits by Platform

Why 150-160 Characters are Optimal

1. Complete Display: Descriptions up to 160 characters are displayed completely in most cases
2. Mobile Optimization: On mobile devices, often only 120-130 characters are displayed
3. CTR Optimization: Shorter, concise descriptions often have higher click-through rates
4. Search Term Integration: Sufficient space for relevant Key Words and call-to-actions

Best Practices for Description Length

2. Call-to-Action (CTA)

• Use action words: "Discover", "Learn", "Buy", "Now"
• Create urgency: "Limited", "Exclusive", "New"
• Communicate benefits: "Free", "Fast", "Easy"

3. Readability and Structure

• Use short sentences (max. 20 words)
• Write actively instead of passively
• Include numbers and data for credibility
• Use emojis sparingly (max. 1-2)
