LinkedIn Ad Copy: Character Limits, Frameworks, and What Converts
LinkedIn Ad Copy: Character Limits, Frameworks, and What Converts
LinkedIn ad copy is the written text of your ad: the intro text, the headline, and the call to action that sit around your creative. Good copy comes down to two things: respecting the character limits so your message is not cut off, and structuring that message so the right person stops and clicks. The limit that matters most is the intro text, which truncates at roughly 150 characters on desktop before a “see more” link, so your hook has to land in the first line. This guide covers what ad copy is, the character limits by format, proven copy frameworks, and the specific choices that make B2B copy convert.
Key takeaways
- Ad copy is the text of your ad: intro text, headline, and CTA. The creative is the image or video; the copy is the words.
- Intro text truncates at about 150 characters on desktop before “see more,” so put the hook and the point in the first line.
- Headlines are cut off permanently past 70 characters, so aim for 50 to 70.
- Use a proven framework like PAS (Problem, Agitation, Solution) or BAB (Before, After, Bridge) rather than writing from scratch.
- Write to one role and one pain, lead with the problem, and make one clear call to action.
What is LinkedIn ad copy?
LinkedIn ad copy is all the written text in an ad: the intro text above the creative, the headline below it, and the call-to-action button. It is distinct from the creative, which is the image, video, or document. Copy and creative work together, but they are judged separately, and copy is usually the faster lever to improve because you can rewrite it in minutes without designing anything new.
The job of ad copy is a qualified click, not just any click. That framing matters because it is easy to write copy that lifts clicks from the wrong people, which raises your CTR and lowers your pipeline.
LinkedIn ad copy character limits by format
Each format has its own limits, and going over them either truncates your message or gets it rejected. These are the current limits for the main formats.
| Format | Intro text | Headline |
|---|---|---|
| Single image | 150 recommended (max 600) | 50 to 70 (cut off past 70) |
| Video | 150 recommended (max 600) | under 70 |
| Document | under 160 recommended (max 600) | under 70 |
| Carousel | 150 recommended (max 255); card text 45 | card headlines, 45 characters |
| Conversation / message | message up to 2,000; subject under 60 | CTA buttons, 25 characters |
| Text ads | not applicable | 25 (description 75) |
| Dynamic ads | not applicable | 50 (CTA 18) |

The intro text truncation rule
The single most important thing about LinkedIn ad copy is where it gets cut off. On a single image or video ad, the intro text shows only about 150 characters on desktop (and fewer on mobile) before collapsing behind a “see more” link. Most people never click “see more,” so anything after that point is effectively invisible.
This changes how you write. Do not warm up with a slow opening line. Put the hook and the core point in the first 150 characters, so that even a reader who never expands the text has seen your message and your reason to click. Treat the space after “see more” as a bonus for the few who expand, not as room for your main argument.
Proven LinkedIn ad copy frameworks
You do not need to invent a structure for every ad. These frameworks work for most B2B sponsored content, and each front-loads the hook into the first 150 characters.
PAS (Problem, Agitation, Solution): name the problem your buyer feels, make the cost of it concrete, then present your solution. Best for cold audiences who need the pain named first.
BAB (Before, After, Bridge): describe the painful before state, paint the better after state, then position your product as the bridge between them. Good for a clear transformation story.
Stat lead: open with a surprising, specific number that reframes the problem, then connect it to your offer. Strong for buyers who respond to data.
Question hook: open with the exact question your buyer is already asking, then answer it. Useful for mid-funnel audiences who are actively evaluating.
Whichever you pick, keep it short. On LinkedIn, shorter copy inside the recommended ranges consistently beats long copy, because the feed rewards a message understood at a glance.
What makes LinkedIn ad copy convert
Beyond a framework, a few specific choices separate copy that pulls qualified clicks from copy that pulls noise. Write to one role and one pain rather than a broad audience, because specific copy signals to the right person that the ad is for them, and you can vary the message by seniority (a sharper, outcome-led line for the C-suite; a more practical one for the people who use the tool). Lead with the problem, not your product. Use concrete numbers over adjectives, because “cut reporting time by 9 hours a week” beats “save time.” Make one ask, not three. And keep the headline and landing page consistent with the ad, because a broken promise after the click wastes the spend.
The copy’s job is a qualified click, so write to attract the buyer and, gently, to repel everyone else. If you want your ad copy judged on the pipeline it produces rather than its click rate, you can book a demo.
Frequently Asked Questions
Q1. What is LinkedIn ad copy?
LinkedIn ad copy is the written text of an ad: the intro text above the creative, the headline below it, and the call-to-action button. It is separate from the creative (the image or video). Copy is usually the fastest lever to improve performance because you can rewrite it without designing anything new.
Q2. What is the character limit for LinkedIn ad copy?
For single image and video sponsored content, intro text has a 600-character maximum but is best kept under about 150, where it truncates on desktop. Headlines are cut off past 70 characters, so aim for 50 to 70. Other formats differ: conversation ads allow up to 2,000 characters, and text ads only 25.
Q3. How long should LinkedIn ad copy be?
Short. Keep intro text under about 150 characters so the hook shows before the “see more” cutoff, and headlines between 50 and 70. Shorter copy within LinkedIn’s recommended ranges consistently outperforms long copy, because the feed rewards a message understood at a glance.
Q4. Where does LinkedIn ad intro text get cut off?
On single image and video ads, intro text collapses behind a “see more” link at about 150 characters on desktop, and fewer on mobile. Most people never expand it, so put your hook and main point in that first line and treat anything after the cutoff as a bonus for the few who click through.
Q5. What are the best frameworks for LinkedIn ad copy?
Two reliable ones are PAS (Problem, Agitation, Solution), which names the pain before the fix, and BAB (Before, After, Bridge), which tells a transformation story. A stat lead (open with a surprising number) and a question hook (open with the buyer’s own question) also work well. Front-load the hook into the first 150 characters.
Q6. How do you write LinkedIn ad copy that converts?
Pick a framework like PAS or BAB, write to one role and one pain, lead with the problem rather than the product, use concrete numbers, and make a single call to action. Keep the headline, body, and landing page consistent, and aim for a qualified click rather than just any click.
Q7. Should LinkedIn ad copy change by seniority?
Yes. The same offer can need different copy by role: a sharper, outcome-led and ROI-focused line for the C-suite, and a more practical, how-it-helps-my-day line for the individual contributors who use the product. Writing one generic message for everyone converts worse than tailoring the angle to the reader.
Q8. What are common LinkedIn ad copy mistakes?
The common ones are burying the hook after the “see more” cutoff, writing headlines over 70 characters that get truncated, speaking to a broad audience instead of one role, stuffing in multiple calls to action, and promising something in the ad that the landing page does not deliver. Each one costs you qualified clicks.
