The hook is the only part of a post most people read. The tester shows each version the way a phone shows it, then checks the habits that make a reader stop or keep scrolling.
The checks are rules of thumb drawn from what tends to work in the feed, not a reading of LinkedIn's algorithm. The best hook is still the one your audience reacts to.
A hook has one job: earn the tap on “…see more”. Four habits do most of the work.
Start with the result, the mistake or the surprise, not the context. The context can wait until line three.
A number, a name or a date reads as real. "5 tips for agencies" sounds generic. "We lost our biggest client in March" does not.
On a phone, aim for under 110 characters, and give the first line its own paragraph so it stands apart.
Draft three angles, a story, a number and an opinion, compare them here, and post the one that sounds most like you.

On mobile, LinkedIn usually shows about three lines, or roughly 140 characters, before "…see more". Desktop shows a little more. The exact cut varies with the device, the font size and the characters you use.
A short first line that gives a reason to keep reading: a result, a mistake, a number or a clear opinion. It says what the post is about and skips the warm-up.
Under 110 characters is a safe target: it fits on a phone with room to spare. Give it its own line so it stands apart from the rest of the post.
No. The score counts how many basic checks a hook passes. Reach still depends on your network, your topic and how readers react in the first hour.
