Why 150-160 Characters are Optimal

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

Best Practices for Description Length

1. Keyword Integration

  • Place primary keyword in the first 120 characters
  • Naturally incorporate secondary keywords
  • Use LSI keywords for semantic relevance

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)

Common Mistakes in Description Length

❌ Too Short Descriptions (under 120 characters)

Problem: Missed opportunities for keywords and CTAs

Solution: Use at least 120 characters

❌ Too Long Descriptions (over 160 characters)

Problem: Gets truncated, important information is lost

Solution: Limit to 150-160 characters

❌ Keyword Stuffing

  • Important keywords in the first 100 characters
  • Short, concise sentences

Responsive Descriptions

Some CMS allow different descriptions for mobile and desktop:
