LinkedIn Viral Score Calculator
A directional engagement heuristic for your LinkedIn post — not a forecast.
This is a directional heuristic, not a prediction: it scores your post against known engagement patterns — hook strength, structure, formatting, length — and flags what is holding it back. Use it as a second opinion before you post, not as a guarantee of any outcome.
What the score actually measures
The score weighs concrete, checkable factors: whether the hook is in the first line, whether paragraphs are feed-readable, whether the post has a clear single idea, and whether it closes with something that invites a reaction. It does not know your audience size, timing, or algorithm changes, so treat it as a formatting and structure check, not a guarantee of any outcome.
How to use the score well
Run your draft through, read the specific flags (not just the number), and fix the concrete issues named — a buried hook, a wall of text, a missing closing question. Re-run after edits to see whether the structural issues are resolved. The number moving is less important than which specific issues got fixed.
What it will not tell you
It cannot account for your specific audience, posting time, current algorithm behavior, or topic saturation that day — no tool honestly can. Do not treat a high score as a guarantee or a low score as a reason not to post; use it as one input, not the final call.
Using the output
If your post scores low on structure, send it to the LinkedIn Post Booster to fix the specific issues flagged. If you want to generate a fresh draft instead, the Post Generator and Hook Generator start from the same underlying formatting principles this tool checks for.
Example outputs
Weak hook, strong body
Input: A post with real insight but the hook buried in paragraph two.
Output: Lower structure score with a flag on hook placement, higher score on substance and length; suggestion to move the insight to line one.
Well-formatted short post
Input: A tight post with a clear hook, short paragraphs, and a closing question.
Output: Higher structure score across hook, formatting, and close, with no major flags raised.

Frequently asked questions
Does this tell me exactly how my post will perform?
No — it is a directional heuristic based on structure and formatting, not a guarantee of engagement outcomes.
What factors does it check?
Hook placement, paragraph structure, formatting for the feed, length, and whether the post closes with a clear invitation to react.
Do I need an account?
No, this instant tool works free with no sign-in.
Can it see my actual audience or past engagement?
No — it is a formula based on the post text alone, not your account data.
What should I do with a low score?
Read the specific flags and fix those issues, or send the post to the Post Booster to fix them automatically.
Can I check the same post after editing?
Yes, re-run it as many times as you like to see whether specific issues were resolved.
