How to check your LinkedIn hook

  1. Paste your first lines

    Paste the hook or the start of your post. Only the first two non-empty lines are scored.

  2. Read the fixes

    Each check says what works and what to change, from length and stock phrases to missing detail and clutter.

  3. Edit until it reads well

    Rewrite in the box and watch the score change. Then copy your hook back into LinkedIn.

A weak hook and a strong hook, side by side

Weak:“I'm excited to announce that our team has been working hard to elevate the customer experience in today's fast-paced landscape.” It opens with a stock phrase, uses three buzzwords and spends a 127-character first line without saying anything specific.

Strong: “I almost fired the only engineer who understood our billing system. Here is what stopped me:” It names a real moment, stays short and ends on a colon that pulls the reader into the next line.

Try both with the example buttons in the checker to see how each one scores.

Fixes for the most common hook problems

Too long. Cut the setup and start with the moment, the number or the claim. Move context to line three.

Too vague. Add one detail you can back up: how many, how long, when or where.

Stock opener.Delete the first clause. “I'm excited to announce we launched X” becomes “We launched X.”

Stuck for an angle? The LinkedIn hook generator gives you 10 or more hooks for your topic in different patterns.

Frequently asked questions

What does the LinkedIn hook checker check?
Nine things in the first two lines of your post: [bracketed] placeholders left in, whether the lines fit in about 130 characters, whether the first line is short, overused openers like “excited to announce”, filler at the start, a concrete detail such as a number or date, a reason to keep reading, buzzwords, and links, hashtags or emoji clutter.
How is the hook score calculated?
Every check starts as a pass. A check that could be better takes 10 points off and a check to fix takes 25 points off a score of 100. Strong is 85 or more, Solid is 70 to 84, and anything lower needs work.
Does a high score mean my post will get more reach?
No. The checker looks at writing habits that help people stop and read. It cannot see your audience, your topic or the LinkedIn algorithm, so treat the score as an editing aid, not a prediction.
How long should a LinkedIn hook be?
Aim for about 130 characters across the first two lines. LinkedIn has no fixed cutoff for every screen, but short hooks are far more likely to show in full before “see more”. See LinkedIn character limits for posts, comments and profiles.
Should I paste only the hook or the whole post?
Either works. The checker scores only the first two non-empty lines, which is what most readers see before they decide to open the post.
Is this LinkedIn hook checker free?
Yes. It is free with no signup, and your text is checked in your browser. The text itself is never sent to WriteHero.
