LinkedIn hook optimizer for recruiters: job posts and thought leadership need different hooks

By Charles Summers · Updated · Free, no signup

Short answer

Recruiters post in two modes that fail differently when truncated. A role post has to get title, seniority, and location past the roughly 140-character mobile cutoff or candidates never learn what the job is. A thought-leadership post fails like a consultant's does, on unproven credibility claims, not on missing facts. This rewrites your draft 8 ways and flags whether your essential job details are inside or outside the truncation point. Every rewrite gets a character count and a truncation flag.

Why recruiters need a different approach

A recruiter posting an open role has a truncation problem no other audience on this list has in quite the same form. Mobile cuts a post around 140 characters before "see more", and a candidate scrolling fast will not tap through for a job they cannot yet identify. A hook like "We're hiring!" wastes the entire visible window on nothing: no title, no seniority, no location, nothing a candidate can pattern-match against their own search in half a second. The essential facts have to survive inside that first 140 characters or the post is invisible to the people it needs to reach.

A recruiter's thought-leadership post (on hiring trends, on candidate experience, on the market) fails a different way. There, the problem is not truncated facts, it is an unproven authority claim, the same trap consultants fall into. "Here's what I've learned placing hundreds of candidates" is unverifiable and generic. This tool asks which mode you're writing in and optimises for the failure that actually applies: missing facts for a role post, missing proof for a thought-leadership post.

It runs entirely in your browser. Nothing you type is sent to a server, no account is required, and there is no usage limit, because there is no cost per run to control.

What does the output look like?

This is the exact output the tool produces from the example inputs. It is generated by the same code that runs when you click the button, so what you see here is what you get.

ORIGINAL DRAFT (59 characters) "We're hiring! Come join our amazing team, link in comments." DIAGNOSIS 1. There is no concrete number in it. A specific figure signals a real result rather than a general claim, and it is the single cheapest upgrade to a weak hook. 8 REWRITTEN HOOKS (tone: bold) 1. [Contrarian] Most advice about a Senior Backend Engineer role, remote US, at a Series B fintech, filling fast because of a hard client deadline is wrong. Here is the version nobody softens. (176 characters OK for desktop) 2. [Specific-number] I spent 12 attempts on a Senior Backend Engineer role, remote US, at a Series B fintech, filling fast because of a hard client deadline. One number mattered: 9 out of 10. (170 characters OK for desktop) 3. [Confession] I got a Senior Backend Engineer role, remote US, at a Series B fintech, filling fast because of a hard client deadline wrong for a long time. Here is what I missed. (164 characters OK for desktop) 4. [Before/after] Before: a flat pipeline. After: a different result in one quarter. Same team, different approach to a Senior Backend Engineer role, remote US, at a Series B fintech, filling fast because of a hard client deadline. (213 characters WARNING: truncated on desktop (over 210 chars), shorten before posting) 5. [Question] What if everything you believe about a Senior Backend Engineer role, remote US, at a Series B fintech, filling fast because of a hard client deadline is backwards? (163 characters OK for desktop) 6. [List-tease] 3 things about a Senior Backend Engineer role, remote US, at a Series B fintech, filling fast because of a hard client deadline nobody tells you until it is too late. (166 characters OK for desktop) 7. [Pattern-interrupt] Stop. If you are still trying to fix a Senior Backend Engineer role, remote US, at a Series B fintech, filling fast because of a hard client deadline by "post more often", read this first. (188 characters OK for desktop) 8. [Stakes] If you are guessing instead of measuring on a Senior Backend Engineer role, remote US, at a Series B fintech, filling fast because of a hard client deadline, you are already behind someone who isn't. (199 characters OK for desktop) How to use this: post one, not all eight. Pick the pattern that matches something actually true about your post, not the one that sounds best in isolation.

Frequently asked questions

What has to survive inside the mobile truncation point for a job post hook?

Title, seniority level, and location, at minimum, and ideally the single most attractive detail (fully remote, salary band, a notable team). If a candidate has to tap "see more" just to learn what the role is, most will not, because there are dozens of other roles in the same feed that did not require the tap. Front-load the identifying facts, not the enthusiasm.

Should I put the application link in the post or the comments?

Comments. LinkedIn suppresses reach on posts with outbound links in the body, and a role post already needs maximum reach to find the right candidate, so trading reach for the convenience of an in-body link is a bad exchange. Post the role, then add the link as the first comment once the post is live.

Why does "join our amazing team" fail as a job post hook?

Because it contains zero information a candidate can act on. It does not say what the role is, what level, or where, so it forces every reader to tap through purely on vibes, which most will not do. Replace the adjective with the fact: the title, not the enthusiasm, is what a job seeker is scanning for.

Does a thought-leadership post need a different hook style than a job post?

Yes, and treating them the same is the most common mistake recruiters make. A job post hook is a compression problem: fit the identifying facts before the cutoff. A thought-leadership hook is a credibility problem: back a claim with a specific placement number or a named pattern from real searches, the same test a consultant's hook has to pass.
