What makes a LinkedIn post perform?

Three things decide whether a post works before anyone reads past the first line: the hook, the cutoff, and the reason to save. LinkedIn shows roughly three lines of your post on mobile before hiding the rest behind "see more". If your first line is a warm-up ("I think", "In today's world", "I'm excited to share"), the post is finished before it starts. The strongest hooks lead with a number, a specific claim, or the middle of a story.

Length matters less than people think, but thinness kills. Posts under 200 characters rarely give anyone a reason to save or share them. Posts over 3,000 characters can work brilliantly if the structure carries the reader: short paragraphs, one idea per line, and a list the reader can come back to.

Why do saves matter more than likes?

A like is a nod in passing. A save is a bookmark, and LinkedIn's feed treats it as a much stronger signal of value. Saves also predict the thing you actually want: being remembered. People save posts they plan to use, which means your post became part of someone's workflow.

The most saveable formats are numbered frameworks, step-by-step breakdowns, and checklists with a clear promise in the first line. If a reader can imagine needing your post next Tuesday, they will save it. That is the test this analyzer scores under "save-rate".

How do you avoid sounding like AI?

Readers have learned the tells fast: uniform sentence lengths, chains of em dashes, bullet-point symmetry, and the vocabulary of nobody in particular ("delve", "leverage", "game-changer"). The fix is not writing worse, it is writing more specifically. Real numbers from your own work. A sentence that is four words long. Contractions, because humans use them.

This analyzer checks for those patterns and penalises them, but the underlying principle is simple: if any professional in your industry could have written the post, it is not building your brand. Specificity is the whole game.

Questions people ask

A LinkedIn post analyzer is a free tool that scores a draft post before you publish. This one rates your post 0 to 100 across five dimensions: hook strength, save-rate prediction, AI-detection risk, the see-more truncation preview, and format match. It returns specific edits so you ship a stronger post instead of guessing.
The save-rate prediction uses heuristics from real high-save LinkedIn posts: numbered frameworks, tactical depth, specific tool names, save-trigger language, and clean structural cues. It is a directional score, not a guarantee. Posts that score 70 plus consistently outperform posts that score below 40 on actual save rate.
Four signals: density of common AI phrases (delve, leverage, in today's fast-paced world, etc.), sentence-length burstiness (humans vary, AI is uniform), vocabulary diversity, and em-dash frequency. The score is the probability your post reads like AI to a critical reader. Anything above 60 percent is worth rewriting.
LinkedIn truncates the feed post after the third visible line on mobile (usually around four lines on desktop). Everything beyond that is hidden until the reader taps see more. The analyzer counts how many mobile-feed lines your hook occupies and scores the cutoff dimension based on whether your strongest line lands above or below that fold.

Under 50 means your draft will likely underperform. 50 to 69 means reach but low conversion to saves or DMs. 70 to 84 is solid and worth posting. 85 plus is rare and tends to compound. Most first drafts land at 55 to 65. The point of the analyzer is to find the specific edits that move you up one band before you publish.
