Key takeaways
- The LinkedIn post analyzer reviews a draft of up to 3,000 characters with nine fixed rules and runs in your browser.
- The same draft always gets the same feedback, because the checks are rules and involve no AI.
- LinkedIn shows a new post to a small slice of your network first and widens the audience based on early reactions, comments and reposts.
- In one analysis of 1,541 LinkedIn posts, posts longer than the fold and first lines ending in a colon won 67% of head-to-head pairs; posts of 100 characters or less won 32%.
A LinkedIn post analyzer reads your draft before it goes live and flags weak spots in the hook, length, spacing, fold, call to action and links. Paste up to 3,000 characters into the box above and you get a labeled finding for each check.
How does the analyzer work?
There are three steps and no account to create:
- Paste the draft
Anything up to 3,000 characters, which is the most LinkedIn accepts in a post. - Go through the findings
Each result has a label and a short explanation in everyday language. - Edit and run it again
Rewrite the parts that were flagged and paste the new version.
Why do most LinkedIn posts get few reactions?
The first line gives no reason to keep reading
It announces the subject and stops there, so the reader has nothing to find out by clicking "see more".
The text is hard to skim
One thick block of words loses people on a phone screen.
Nothing invites a reply
Without an opinion to react to or a question to answer, readers move on.
Filler words water down the message
A sentence that adds nothing still asks for the reader's attention, and each one makes the post feel longer.
Which checks does the analyzer run?
It applies a fixed set of rules instead of guessing, so pasting the same text twice returns the same feedback. The nine checks:
- Hook: whether the opening line gives a reason to read or only names the subject.
- Length: long enough to go past the fold, short enough that people finish it.
- Scannability: line breaks, short paragraphs and a varied rhythm.
- "See more" fold: what appears in the first ~210 characters on desktop and the first ~140 on mobile.
- Hashtags: a handful that fit the topic instead of a long block.
- Question or call to action: something people can answer in the comments.
- Links: whether a link sits in the post body; the first comment is an option.
- Ending: a last line that asks for a response.
- Emoji and ALL-CAPS: used sparingly.
How does LinkedIn distribute a post in its first hours?
LinkedIn starts by showing a new post to a small part of your network. The reactions, comments and reposts it gets in that window tell LinkedIn whether to show it to more people. Comments count the most, because writing one takes effort and keeps people on the post longer.
That is the reason to fix the draft before publishing. The hook and the opening lines decide whether that first small audience responds at all.
Which hooks and formats hold attention?
Treat the first line as a separate piece of writing. A number, a clear claim or a concrete result works better than an opener that sets the scene. One analysis of 1,541 LinkedIn posts compared them in head-to-head pairs: posts that ran past the fold and first lines that ended in a colon won 67% of their pairs, and short posts of 100 characters or less won only 32%.
Break the text into short paragraphs with line breaks between them so it reads easily on a phone. The LinkedIn line break generator keeps that spacing intact when you paste.
How do you measure the result after publishing?
Once the post is live, track its impressions, reactions, comments and reposts, then divide the interactions by impressions with the LinkedIn engagement rate calculator. Compare the figure with your own last few posts; one industry-wide number tells you less about your account.

What should you do once the draft is ready?
Publish it and make sure the first hour has some activity. On LinkedInLikes, members react to and comment on each other's posts by hand from their own accounts, and comments are written in each member's own words.
New accounts start with 100 points for their own posts. See how it works for likes and for comments.
Frequently asked questions

No. It is a set of rules, which is why the same draft always gets the same feedback.
No. It checks the structure of the text. How people react to the idea itself depends on your audience.

If a link matters, think about putting it in the first comment instead of the post body.
