You publish a great article, paste the link into LinkedIn, and the preview shows an old image, a wrong title, or nothing at all. Your post looks unprofessional before anyone reads a word.
This is the problem LinkedIn Post Inspector solves. It’s a free tool that shows you exactly how LinkedIn sees your link and lets you refresh that preview in seconds. Here’s how it works and what to do when it doesn’t.
LinkedIn Post Inspector: What It Does and Why It Matters
LinkedIn Post Inspector is an official LinkedIn tool that lets you preview and debug link previews before (or after) you share a URL. When you paste a link into a post, LinkedIn’s crawler visits the page, reads its metadata, and builds a preview card with a title, description, and thumbnail image.
The catch is that LinkedIn caches this information. If you change your headline, swap your featured image, or fix a typo after the page was first crawled, LinkedIn may keep showing the old version for days. Post Inspector lets you force a fresh crawl.
It matters because the link preview is often the first thing people notice in the feed. A sharp image and a clear headline can be the difference between a scroll-past and a click. For marketers, bloggers, and founders, a broken preview means lost traffic and a weaker first impression.
Post Inspector: A Tool to Optimize Content Sharing
Think of Post Inspector as a quality check for your content sharing. It helps you:
- See what LinkedIn sees. You get a live look at the title, description, and image the crawler pulls from your page.
- Clear outdated previews. Re-inspecting a URL refreshes the cached data.
- Spot metadata problems. Missing or malformed tags show up quickly.
- Test before you promote. You can check a link before it goes into a post, newsletter, or ad campaign.
If you publish regularly, building this check into your workflow takes about thirty seconds and can save a post that would otherwise flop.
How to Use LinkedIn Post Inspector (Step by Step)
Using the tool is simple:
- Open Post Inspector. Go to linkedin.com/post-inspector and sign in to your LinkedIn account.
- Paste your URL. Enter the full link of the page or article you want to share.
- Click “Inspect.” LinkedIn fetches the page and shows the preview data it found.
- Review the results. Check the title, description, image, and the last-scraped date.
- Re-inspect if needed. If the preview is outdated, click Inspect again. This triggers a new crawl and updates the cache.
- Share your post. Paste the link into LinkedIn and confirm the preview looks right.
Tip: Always use the exact URL you plan to share. A version with tracking parameters or a different slug can be cached separately.
Preview and Debug Link Previews: What to Check
LinkedIn builds previews mainly from Open Graph (OG) tags in your page’s HTML. Here are the ones that matter:
- og:title: the headline shown on the card. Keep it clear and under about 70 characters so it doesn’t get cut off.
- og:description: a short summary. Write it like a mini hook, not a keyword dump.
- og:image: the thumbnail. A 1200 × 627 px image (roughly a 1.91:1 ratio) displays well.
- og:url: the canonical address of the page.
If you use WordPress, Shopify, Webflow, or a similar platform, SEO plugins like Yoast or Rank Math can set these tags for you. Check that the fields are filled in for every page you plan to share.
LinkedIn Post Inspector Not Working? Common Fixes
Sometimes the tool itself seems to fail, or the preview stays broken even after you inspect. Here are the most common causes and fixes.
1. The old preview won’t go away
Click Inspect again, sometimes two or three times, and wait a moment. If it still looks stale, make sure you’re testing the exact URL you’re posting. Also note that posts that are already published usually keep their old preview. Create a new post to see the refreshed card.
2. The image is missing or wrong
Check that your og:image tag exists and uses an absolute URL (starting with https://). Make sure the image is publicly accessible, not behind a login, and not blocked by hotlink protection. Very small or very large files can also fail, so stick to a reasonable size and standard formats like JPG or PNG.
3. LinkedIn can’t fetch the page
If Post Inspector reports an error, your server may be blocking LinkedIn’s crawler. Review your robots.txt file, firewall, CDN, or security plugin settings and make sure LinkedInBot isn’t being denied. Pages that return errors, redirect in loops, or load very slowly can also fail.
4. Metadata is missing or duplicated
Conflicting tags, for example two og:title entries from a theme and a plugin, can confuse the crawler. View your page source and search for “og:” to confirm each tag appears once with the right value.
5. Content is rendered by JavaScript
If your meta tags are injected only after JavaScript runs, the crawler may not see them. Make sure Open Graph tags are present in the initial HTML the server sends.
6. The tool is down or acting up
Occasionally LinkedIn’s own tools glitch. Try logging out and back in, using a different browser or incognito window, or coming back later.
Best Practices for Better LinkedIn Link Previews
- Write for humans first. A specific, benefit-driven title beats a keyword-stuffed one.
- Use a custom image for every post. Generic or default images blend into the feed.
- Keep text away from the image edges. Cropping can cut off important details.
- Inspect before you announce. Run new links through Post Inspector before sharing them in posts, emails, or paid campaigns.
- Re-inspect after edits. Any time you change a title, description, or image, refresh the cache.
- Keep URLs consistent. Use one clean canonical URL instead of many variations.
Final Thoughts
LinkedIn Post Inspector is a small tool with a big payoff. It shows you exactly how your link will appear, clears out stale previews, and helps you catch metadata problems before your audience does. If a link preview ever looks off, paste the URL, click Inspect, check your Open Graph tags, and try again.
Making it part of your publishing routine means your content always makes a strong first impression, and that’s often what earns the click.
FAQs
Is LinkedIn Post Inspector free?
Yes. It’s free to use with a LinkedIn account.
How long does LinkedIn cache link previews?
LinkedIn typically holds onto preview data for a while, often around a week, which is why re-inspecting the URL is the fastest way to refresh it.
Why is my LinkedIn link preview not updating?
Usually it’s caching, an incorrect URL, missing Open Graph tags, or a crawler being blocked. Re-inspect the exact link and check your page source.
Does Post Inspector change already published posts?
Generally no. Existing posts tend to keep the preview they were created with, so share the link in a new post after refreshing.
