Four copy rules the data supports
- Open with the offer as a statement. A question first line gets 64% fewer leads per impression in the same account (question hooks).
- Do not name the reader's job title in the first line. It cuts leads per impression by 54%.
- Fit the hook in 150 characters. That is how much intro text shows before "see more" (ad specs).
- One ask per ad. The form or the page does the qualifying; the ad only has to earn the open.
The examples below are written for this page to show the pattern, with placeholders in brackets. The benchmarks are medians across advertiser accounts in the Kiin Labs panel.
1. Single image ad to a landing page
Intro: Most [category] teams lose 3 hours a week to [problem]. Here is the checklist we use to get it back. Headline: The [problem] checklist, free Button: Learn more
What it should hit: single image is the cheapest real visit on LinkedIn: $13.63 per landing page click at the median account across 774 advertisers, with a median landing page CTR of 0.24%. Below 0.24%, change the image and first line before the audience.
2. Single image ad with a lead gen form, content offer
Intro: The 2026 [category] benchmark: what 400 teams spend, by company size. 12 pages, no email chain. Headline: Get the benchmark Button: Download
What it should hit: $164 per content lead at the median account, $67 in the top quarter. Templates and tools are the cheapest offer at $110 a lead; reports run $199. Keep the form to pre-filled fields: a phone number field cuts completion by 66%.
3. Document ad, gated after page two
Intro: Pages 1 and 2 of our [topic] playbook are below. The other 14 are one click away. Document: 16-page PDF, form after page 2 Button: Unlock
What it should hit: document ads get the fewest form opens of any feed format (0.14 per 100 impressions) and the most finishes: 21% of openers submit, and in the same account a document lead costs 22% less than a single image lead. The best home for a content offer.
4. Message ad with a demo form
Subject: [First name], a 20-minute look at your [problem] Body: Hi [first name], you have been reading our [topic] guides this month. If it is useful, I will walk you through how [similar company] cut [metric] by putting your numbers next to theirs. Pick a slot below. Button: Book 20 minutes
What it should hit: 41% of people who open the form from a message submit it, against 5% in the feed, and in the same account a message ad lead cost $232 against $302 from a single image form, cheaper in 46 of 65 accounts (message vs form). Send it to a retargeting pool, not a cold list.
5. Conversation ad with two buttons
Message: Hi [first name], quick one. Are you looking at [category] this quarter, or later this year? Button 1: This quarter, show me a demo Button 2: Later, send me the benchmark
What it should hit: $0.48 per send and a 40.7% open rate at the median account (190 accounts), and leads per send flat at 0.16 to 0.17% every day of the week. Bid low: the highest bid in an account paid 80% more per send for the same open rate. The full playbook is in conversation ads.
6. Thought leader ad from a founder
Post from the founder's own profile: We looked at 300 of our customers' [process]. The ones who did [one thing] closed [X] times faster. Here is what that one thing is, and the mistake we made before we saw it. [3 short paragraphs, no link in the first line]
What it should hit: judge it on engagement, not clicks: 91% of the clicks LinkedIn reports on thought leader ads never reach a landing page, and a real visit costs $25.02 on a single image thought leader ad (Report No. 1). Its job is to fill the retargeting pool that examples 4 and 5 sell to.
7. Video ad for the retargeting pool
15 seconds, square, captions on. Second 1: the problem on screen in five words. Seconds 2 to 12: one proof point. Last 3 seconds: the offer, no logo animation.
What it should hit: $40.93 CPM and $33.68 per landing page click at the median account. Video is the dearest common way to buy a visit and a cheap way to build an audience: retarget everyone who watched 50% or more.
8. Carousel ad, one idea per card
Card 1: The 5 numbers your board will ask about [topic] Cards 2 to 6: one number per card, large type Last card: Get all five as a one-page template
What it should hit: $14.01 per landing page click at the median account, close to single image, with a $54.01 CPM. Worth it when the content genuinely splits into cards; otherwise a single image does the same job for less.
9. Event ad for a LinkedIn Live or webinar
Event: [Topic] in 2026: what changed, live with [speaker] Intro: 40 minutes, 3 numbers, live Q&A. Thursday 4pm UK. Button: Register
What it should hit: $49.36 CPM and $21.61 per landing page click (75 accounts). If registration lives on your own site, a single image ad to the registration page gets the click for less and lets you retarget by page visit.
