LinkedIn post checker

Paste a draft and get plain checks on the fold, the first line, length, hashtags and endings, each with its reason. Nothing you type leaves your browser.

5 to look at

This is a sample with the usual problems. Replace it with your own draft.

The checks

5 of 11 checks want a second look, 6 are fine.

  • Above the fold: fine

    The feed shows roughly the first 210 characters, fewer on a phone, and hides the other 431 behind “…more”.

    I'm excited to share that we finally shipped the new onboarding last week! It took the team four months, three rewrites and more meetings than anyone wants to remember, and along the way we learned a lot about

  • First line: fine

    The first line is 74 characters and 13 words: it survives the cut on a phone, though under about 8 words reads fastest.

    I'm excited to share that we finally shipped the new onboarding last week!

  • Opening words: look again

    It opens with “I'm excited to share”, which starts with you; open with what the reader is dealing with and let the news come later.

  • Length: fine

    641 of LinkedIn's 3,000 characters.

  • Walls of text: look again

    One paragraph runs to 282 characters without a line break, which reads as a wall on a phone; split it into one thought per line.

    It took the team four months, three rewrites and more meetings than anyone wants to rememb…

  • Hashtags: look again

    7 hashtags is more than a handful; keep the few that help someone find the post and put them at the very end.

  • Links: look again

    There is a link in the post; make sure it still makes its point for the people who never click.

  • Endings: look again

    It ends with a question, a call to action, a link and hashtags: four endings, where one, at most two, is what a post can carry.

  • Capitals: fine

    No shouting: nothing beyond the odd acronym or single word is in capitals.

  • Emojis: fine

    3 emojis in 9 lines, and no row of them.

  • Unicode styling: fine

    No Unicode bold, italic or underline, so a screen reader and the search read every word.

A tick means the draft does what our guides advise. An amber mark means look again; it is a prompt, not a verdict. There is no score: the checker cannot know how a post will do, so it does not guess.

The rules, in the open

What the checker looks at

The fold and the first line

In the feed, LinkedIn shows roughly the first three lines of a post — about 210 characters on a desktop screen, fewer on a phone — and hides the rest behind “…more”. The checker shows you the part above that line and the first line on its own. It warns when the first line runs past about 80 characters, because that is where it wraps and gets cut mid-thought on a phone, and it notes that a line under about eight words reads fastest.

Opening words

It looks for the openings our guides rule out: “I'm excited to share” and its relatives, a greeting, a date, thanks, an announcement of an announcement, and bait such as “You won't believe”. It reads the first line only and recognises wording, not meaning, so a first line that passes can still be a warm-up.

Length and walls of text

LinkedIn's limit is 3,000 characters, and past it the post cannot be published. Before that, the checker asks whether a post over 1,500 characters is really two posts, and flags any paragraph that runs past 250 characters without a line break. That is about five lines on a phone, which is where a paragraph turns into a wall.

Hashtags, links and endings

Hashtags are for discovery: a handful, which the checker reads as up to five, at the very end. A link is not a mistake; the check is a reminder that the post has to make its point for the people who never click. And a question, a call to action, a link and hashtags are four ways to end a post. The checker counts how many yours uses, because one, at most two, is what a post can carry, and it asks for a specific question where it finds “Agree?” or “Thoughts?”.

Capitals, emojis and Unicode styling

ALL CAPS and a row of emojis are patterns readers have learned to skip. The checker warns about a first line in capitals, two or more shouted words, three emojis in a row, or more emojis than lines. It also counts the letters in Unicode bold, italic or underline, which screen readers read badly: a few words are fine, more than 40 letters are not.

What it does not do

There is no score and no percentage. The checker cannot know what LinkedIn's feed will do with a post, so it does not pretend to. Every check is a rule you can read in the guides below, applied the same way each time: a tick means the draft does what the guides advise, an amber mark means look again, not that something is wrong. A draft can pass all of them and still have nothing to say. That part is yours.

Privacy

The page runs entirely in your browser. Nothing you type is sent to MediaPilot or anyone else, nothing is stored, and there is no account. If you use the button above, the draft is carried into the signup on your own device so you do not have to paste it again.

The rules come from How long should a LinkedIn post be?, How to write a hook people actually read and How to write LinkedIn hooks that stop the scroll. To see the cut itself, use the post preview.
