LinkedIn Ads Copywriting: The Golden 70-Character Mobile Limit

LinkedIn is the world's #1 B2B social advertising platform, connecting brands with over 1 billion professionals and senior decision-makers. However, B2B executives browse LinkedIn predominantly on mobile devices. While LinkedIn technically allows up to 200 characters in ad headlines, headlines over 70 characters are ruthlessly truncated with an ellipsis (...) on mobile app feeds.

LinkedIn Sponsored Content Ad Specifications

  • Headline Character Limit: 200 characters max, but strictly ≤ 70 characters to prevent mobile truncation.
  • Introductory Text: Up to 600 characters (first 150 characters visible before the "...see more" fold).
  • Call to Action (CTA): Selectable buttons including Learn More, Download, Sign Up, and Request Demo.
  • Primary Format: Single Image Ads and Video Ads in 1:1 square or 1.91:1 horizontal ratios.

4 High-Converting B2B Headline Frameworks

2. Problem-Agitate-Solve (Pain Points)

3. Industry Benchmarks & Reports

C-suite professionals crave competitive intelligence. "The 2026 Executive Benchmark" positions your brand as an essential advisor.

For bottom-of-funnel retargeting audiences, direct invitations to book a 10-minute demo or start a trial convert at peak efficiency.

Frequently Asked Questions (FAQ)

What is the recommended LinkedIn ad headline length?

Keep headlines under 70 characters. While LinkedIn allows up to 200 characters, anything above 70 is truncated on mobile feeds.

How does LinkedIn Ad copy differ from Google or Facebook ads?

LinkedIn copy must be tailored to professional buyer personas, focusing on organizational ROI, risk reduction, industry benchmarking, and career empowerment rather than casual consumer lifestyle hooks.

What is an average CTR for LinkedIn Sponsored Content ads?

Across LinkedIn benchmarks, an average click-through rate ranges from 0.40% to 0.60%. High-performing ads with punchy mobile-safe headlines can exceed 1.0% to 1.5% CTR.
