Scoring is fine. KAIROS writes posts that score 80+ — in your voice, on your schedule, posted when LinkedIn rewards you most.
See how it worksWhy this exists
Most LinkedIn posts get scrolled past in under 2 seconds. Not because the content is bad — because the first line buried the hook, the structure was a wall of text on mobile, or the closing CTA was a generic 'thoughts?' that didn't earn a comment. The tool measures all four of those dimensions and gives you a number you can iterate against.
The score isn't a vanity metric. It's calibrated against what LinkedIn actually rewards in 2026: scroll-stopping hooks, scannable structure, founder voice that sounds like a person (not an LLM), and CTAs specific enough that people can't help but reply. Optimize against the dimensions, not against the score.
Use it before every post that matters. Paste the draft, get the score, fix the lowest-rated dimension, paste again. Two iterations usually move a 50 to a 70 — which roughly doubles predicted engagement on the typical founder audience.
The framework
The 4 dimensions of a LinkedIn post that performs
- HookHK
- The hook is the first 1-2 lines of a LinkedIn post that determine whether the reader scrolls past or stops to read. Strong hooks are specific, contrarian, or pattern-interrupt — generic intros ("Excited to share…") get scrolled in under a second.
- StructureST
- Structure is the visual rhythm of a LinkedIn post on the mobile feed — line breaks, paragraph length, scannability. LinkedIn rewards posts that read as bites, not as walls. Two-line chunks with blank lines between them outperform dense paragraphs almost universally.
- VoiceVC
- Voice is the founder's authentic and specific style — concrete numbers, named tools, real moments. Generic startup-speak ("lessons learned", "journey", "authentic") reads as AI-generated and gets ignored. Specificity is what makes a voice unmistakable.
- CTACT
- The CTA (call to action) is the closing ask of a LinkedIn post — typically a question that earns a comment. Specific questions outperform vague ones; "Thoughts?" is the worst CTA on the platform. The strongest CTAs name a specific scenario the reader has lived through.
How it works
- 1Paste your LinkedIn draft (50 to 3,000 characters — LinkedIn's hard limit).
- 2Wait 5 seconds while the analyzer scores all four dimensions and predicts engagement against typical founder audiences.
- 3Read the breakdown — fix the lowest-rated dimension first, then the second-lowest. Don't try to fix all five fixes at once.
- 4Paste the rewrite. Two iterations usually move a 50 to a 70 — that's the leverage.
When to use this
Use it before every LinkedIn post that matters. The 5-second cost is worth it before you spend an hour writing — and even more worth it before the algorithm decides to bury a post you spent 30 minutes drafting.
Frequently asked
What's a good LinkedIn post score?
60+ is solid for a typical founder audience. 75+ predicts above-average engagement (200+ likes on a 2k-follower account). Most drafts score between 45 and 70 on first pass; resist grade inflation when you self-evaluate.
How accurate is the predicted engagement range?
It's calibrated against typical founder LinkedIn audiences (around 2,000 followers). Treat it as a directional range, not a forecast — actual reach depends on the algorithm, your network density, and timing factors no tool can predict.
Should I use emojis in my LinkedIn posts?
Sparingly. Emojis can break visual monotony but they don't lift engagement on their own. The bigger lever is structure (line breaks) and a specific CTA. Don't add emojis to every fix the tool returns — some industries (B2B SaaS, deep tech) genuinely hate them.
How long should a LinkedIn post be?
1,300 to 1,900 characters performs best for most founders. Shorter posts (under 500) work for hot takes; longer posts (above 2,200) work for storytelling but require very strong hooks. The character count itself isn't the ranking factor — readability and the hook are.
Where should I put hashtags?
At the bottom, not the top. Hashtags at the top of the post hurt the algorithmic boost LinkedIn gives a fresh post. Three to five specific hashtags at the bottom is the standard — and a single industry-specific hashtag often outperforms a stack of generic ones.
Why does my LinkedIn post get no engagement?
Three usual culprits: (1) a generic hook that didn't stop the scroll, (2) wall-of-text structure that lost mobile readers, (3) a vague CTA like 'thoughts?' that didn't earn a comment. Score the post — the lowest-rated dimension is your biggest single lever.
Does posting time matter on LinkedIn?
Yes, but less than founders think. The first 60 minutes determine whether the post gets the next 24 hours of distribution, so posting when your audience is on the platform matters. But a 75-score post at the wrong time will outperform a 50-score post at the perfect time. Quality > timing.
Should I use the LinkedIn algorithm tricks I see on Twitter?
No. Most "algorithm hacks" (pod groups, hidden hashtags, comment-baiting) get throttled within a few months of going public. The durable strategy is: strong hooks, scannable structure, specific voice, real CTAs. The dimensions this tool scores are the ones LinkedIn actually rewards in the long run.
