Writing copy that fits and performs
Hitting the limit isn't the same as writing a great ad.
Headlines are the funnel
80% of CTR comes from the first headline. Lead with the strongest hook — ad platforms test variants regardless, but Headline 1 sets the impression.
Watch description truncation
On mobile, Google often shows only Description 1. Front-load the value prop in the first 40 characters — before users have to expand or scroll.
Copy length isn't quality
Hitting the limit doesn't make copy stronger. The best ads use 60-70% of available characters — they're scannable, specific, and easy to skim on mobile.
Frequently asked questions
What are the actual character limits?
Google Search Ads: 30 characters per headline (3 headlines), 90 characters per description (2 descriptions). Meta (Facebook/Instagram): 40-character headline, 30-character description, 125-character primary text recommended. LinkedIn: 70-character headline, 150-character intro text. These reflect 2024 specs.
Do platforms count emoji as characters?
Most do — and many emoji count as 2+ characters because of multi-byte encoding. Always test each emoji in the platform's preview tool before launching.
Should I always max out the character limit?
No. Test shorter copy — sometimes 50% of the limit outperforms because it's more scannable on mobile. The best ads use 60-70% of available characters.
Are there penalties for going over?
Yes — your ad won't run. Platforms reject ads that exceed character limits at upload, and you'll need to edit and resubmit before they enter review.
