One LinkedIn post preview tool. Three things you need to check.
Most people publish without checking how their post looks in the feed. This tool shows the three things that matter most.
See exactly where LinkedIn truncates your post. Desktop shows 5 lines for text-only, 3 for posts with media. Mobile shows just 2 lines.
Toggle between desktop and mobile preview. Mobile shows far less text before the fold, so your hook needs to be tighter. 70% of LinkedIn usage is mobile.
Check how line breaks, emojis, and spacing render in the feed. Blank lines eat into visible hook space, so every line break is a strategic choice.

How LinkedIn's "see more" works and why it controls your reach
LinkedIn doesn't show your full post in the feed. Every post is truncated with a "...see more" link. The amount of text visible before the cutoff depends on two things: your device and whether your post includes media. A LinkedIn post preview tool like this one helps you see exactly what's visible before you publish.
The truncation is line-based, not character-based. A blank line counts as a full line. So if your hook uses a line break for dramatic spacing, that blank line eats into your visible area. On mobile, a hook with one blank line leaves you with just one line of visible text before "see more."
Why the "see more" click rate matters
LinkedIn measures engagement velocity: how quickly people interact with your post after publishing. The "see more" click is the first engagement signal. If people scroll past without clicking, the algorithm limits your post's reach. A strong hook that's visible before the fold dramatically increases your click-through rate, which drives more impressions, comments, and shares. This is exactly why previewing every post with a LinkedIn post preview tool is worth the 10 seconds it takes.
How to optimize your hook for the fold
Use this free LinkedIn post preview tool to test your opening lines across both devices. The goal is to create a curiosity gap within the visible lines. The reader should feel compelled to click "see more" to get the answer, the result, or the punchline. Short sentences, specific numbers, and open loops work best.
Your post's reach is decided in the first 2-5 lines. This LinkedIn post preview tool shows you exactly what's visible before "see more" on every device. Preview every post before publishing. For help writing the opening line, try our LinkedIn hook generator.
Optimize your post for maximum "see more" clicks
Follow these guidelines to make your hook work harder.
Do This
Front-load your strongest line. The first sentence should create a curiosity gap.
Use specific numbers in the first line ('247 emails' not 'hundreds of emails')
Test your post on mobile preview. Most LinkedIn users are on mobile.
Keep your hook under 2 lines if you're posting with an image or document
Preview every post before publishing. 10 seconds of checking saves hours of weak reach.
Avoid This
Starting with a blank line for spacing. It wastes your most valuable visible line.
Using generic openers like 'Excited to share...' or 'I'm thrilled to announce...'
Burying the actual hook below a context-setting paragraph
Assuming desktop preview equals mobile. Mobile shows 60% less text.
Publishing without checking how your post renders in the actual feed
