Free LinkedIn hook grader

The LinkedIn hook grader is a free tool that checks the first line of a post against simple rules of thumb: length, specificity, clichés and engagement bait. It explains every check so you can decide what to change. It runs in your browser, needs no login, and does not predict reach.

Rule-of-thumb score

100 / 100

  • PassShort enough to read at a glance

    The first line is short enough to take in at a glance.

  • PassSays something on its own

    The line has enough words to carry an idea by itself.

  • PassIncludes a concrete detail

    Numbers, names, places and dates make a hook specific. A concrete detail tells the right reader the post is about their world.

  • PassAvoids stock openers

    Openers like "In today's..." or "I'm excited to..." are so common that readers skip them. Lead with the point instead.

  • PassNo engagement bait

    Asking people to comment a keyword, like or tag others attracts low-intent engagement. LinkedIn asks members not to artificially increase engagement.

  • PassNot shouting

    All-caps lines read as shouting. Use plain case and let the idea do the work.

How it works

Paste the opening of your post. The grader looks at the first line, the part readers see before deciding whether to keep reading.

Each check is a rule of thumb, not a ranking factor LinkedIn has published. LinkedIn has said it treats quick skips as a negative signal and wants to limit click bait, so the grader rewards hooks that are specific and honest about what the post delivers.

Use the score to compare versions of the same hook, not to compare different posts. The real test is whether the right readers comment and start conversations.

Frequently asked questions

What makes a good LinkedIn hook?

A good hook is specific and true to the post: it names a problem the reader recognizes, takes a clear position or opens a story with a concrete detail, and the body delivers on it.

Does a higher score mean more reach?

No. The grader applies rules of thumb to the wording. Reach depends on your audience, the topic and how people respond. Use the score to compare drafts of the same hook.

Does the hook grader use AI or store my text?

No. The checks run in your browser using fixed rules, and nothing you type is sent anywhere.
