What it does

Check ad headlines and descriptions against the real character limits on Google Ads (30 / 90), Meta (40 / 125), LinkedIn (70 / 600), and others. Each field shows a progress bar against its platform limit, so you see at a glance which variants still need trimming.

For broader headline scoring use headline analyzer. For email lines, email subject line tester. For plain character counts, character counter.

How to use it

  1. Pick a platform: Google, Meta, LinkedIn, X.
  2. Type each headline and description variant.
  3. Watch the per-field bars — amber = close, red = over.
  4. Copy the compliant variants into your ad manager.
