Stop guessing. Here's what works.
We analyzed 12,000+ LinkedIn posts from 800+ accounts with 5K–15K followers over the last 90 days. Data-backed rules for what to do — and what to stop doing — right now.
One formula. Apply it every time.
If you do nothing else from this report, apply this formula to your next post.
Image + Personal Story hook + 1000–2000 chars + Weekday at 7 AM EST
10 things to change starting today
Each rule is backed by the dataset. Relative performance is shown so you can weigh confidence.
Post images — they outperform everything
Do thisImage posts average ~40 likes, ahead of carousels (~33), video (~27), and text (~20). Over half of all posts in the data are images — and they still win. The advantage is real and consistent.
Write longer — 1000-2000 characters is the sweet spot
Do thisPosts in the 1000–2000 char range average ~36 likes. Posts under 100 chars average ~20. The algorithm rewards dwell time — give readers something worth stopping for.
Open with a personal story
Do thisPersonal story hooks (“I almost quit…”, “Last year I…”) outperform every other hook type. They average ~42 likes vs ~30 for generic statements. People connect with people, not platitudes.
The #1 combo: Image + Personal Story
Do thisImage posts paired with a personal story hook are the highest-engagement combination in the dataset. This combo outperforms every other format×hook pairing. Image + Number-led is a close second.
Drop the hashtags — zero is the magic number
Do thisPosts with zero hashtags outperform every hashtag count. No hashtags: ~34 avg likes. 4-5 hashtags: ~21 avg likes. Hashtags dilute your signal and make posts look templated.
Use line break spacing — it’s a 42% lift
Do thisPosts with double-line-break spacing (readable paragraph gaps) get ~42% more engagement than wall-of-text posts. Make your post scannable. White space is a feature, not wasted real estate.
Include links — they double engagement
Do thisPosts with links average ~51 likes vs ~25 without. This likely correlates with authority signaling — linking to a resource, article, or company page signals depth and credibility.
ALL CAPS your first line — it’s a 48% lift
Do thisPosts where the first line is ALL CAPS average ~45 likes vs ~31 otherwise. It’s a scroll-stopper. Use it intentionally and sparingly — when you have a bold, declarative opener.
End with a CTA, but never open with one
Do thisPosts ending with a call to action (“follow for more”, “check the link”) get ~40% more engagement. But CTA-led hooks (“Comment GUIDE to get…”) as the opening line are one of the worst hook types. Close with CTA, open with value.
Stop posting articles
Stop thisArticles average just ~15 likes — the lowest of any format. They take the reader off the feed, killing dwell time on the platform. The algorithm deprioritizes them. Put that effort into image posts instead.
Post when the competition is asleep
Relative engagement by day, hour, and their best combos.
Days are fairly even — consistency matters more than day selection.
All times in EST. 7 AM is the clear winner. Early morning (4–5 AM) and late morning (9–11 AM) are strong secondary slots.
All times in EST. Afternoon 3–5 PM on weekends and Thursdays is a dead zone.
Every hook type ranked
| Hook type | Relative performance | Verdict |
|---|---|---|
Personal Story “I almost quit LinkedIn 6 months ago.” | Likes Comments Reposts | Best overall |
Number-led “7 things I learned building to 10K followers.” | Likes Comments Reposts | Strong reach |
How-to “How I grew 2K followers without posting daily.” | Likes Comments Reposts | Good for depth |
Statement “This is why most LinkedIn advice is wrong.” | Likes Comments Reposts | Reliable default |
Question “What happens when you stop posting for 30 days?” | Likes Comments Reposts | Drives replies |
CTA-led “Comment GUIDE to get my free resource.” | Likes Comments Reposts | Only as a closer |
Negative Command “Stop optimizing your LinkedIn profile.” | Likes Comments Reposts | Low performer |
The exact combination for your next post
| Personal Story | Number-led | Statement | Question | |
|---|---|---|---|---|
| image | 66 | 65 | 49 | 43 |
| carousel | 66 | 60 | 41 | 33 |
| video | 43 | 39 | 36 | 23 |
| text | 37 | 22 | 26 | 17 |
| article | 25 | — | 17 | 15 |
Relative total engagement. Darker = better combo.
Small tweaks that compound
Zero hashtags outperforms. If you must use them, stay under 3.
The 1000–2000 character range is the sweet spot.
Longer hooks (101–150 chars) outperform short punchy ones.
Dense writing with substance outperforms bullet-point posts.
