A grader tells you what's wrong. Mylance helps you write it right.
Mylance is built on exactly this data. It pushes you toward the levers that win (specificity, emotional pull) and turns your real thinking into posts that sound like you. Drop your LinkedIn handle for a free positioning and content plan.
What the grader scores (and why)
Every criterion below traces to a backtest of 895 real LinkedIn posts from 37 creators, where each post was scored against its own author's median so audience size couldn't fake the results. The full method and findings are in the study.
Emotional pull
The strongest lever we found: 70% of high-emotion posts beat their baseline.
Specificity
Concrete beats abstract, 68% vs ~50%. Real numbers and named things.
Length
Don't be short: under 400 chars beat baseline only 33% of the time.
A number in the hook
A result in the first line beats 61% vs 52%.
Link placement
A link in the body beats just 41% vs 56%. Put it in the comments.
Image
Posts with an image beat baseline 61% vs 54%.
Frequently asked questions
How does the LinkedIn post grader work?
It scores your post against the levers that actually predicted engagement in a backtest of 895 real posts: emotional pull, specificity, length, whether you lead with a number, link placement, and image. It runs entirely in your browser. Nothing is stored or sent anywhere.
What makes a good LinkedIn post?
In the data, the biggest levers were emotional pull (a stake or a moment of being seen) and specificity (real numbers, named things), not polish. Say enough (short posts underperform), lead with a result, keep links in the comments, and add an image.
Is a longer LinkedIn post bad?
No. This is a myth. Posts over 2,000 characters beat their baseline 59% of the time, one of the best buckets. The real killer is being too short: posts under 400 characters beat baseline only 33% of the time.
Should I put links in my LinkedIn post?
Not in the body. Posts with a link in the body beat baseline just 41% of the time versus 56% without. Put the link in the first comment instead.
